Product Info

Manufacturer Description

New, improved design - Now with two large thumbscrews!

This high-quality Blue Fireball extension tube can be inserted into any 2" telescope focuser to gain an additional 35mm (1.38") of back-focus travel. With this, eyepieces and accessories that you may not have been able to use because your telescope tube was too short are usable again!

Lack of sufficient back-focus travel is a common problem with many of today's fast f-ratio telescopes, especially if you have a low profile focuser or a short telescope tube that is optimized for binoviewer viewing. The 35mm extension tube alleviates this problem. This tube can also be used with 1.25" accessories with the use of commonly available 1.25"-2" adapters (sold separately).

This practical and superb quality adapter is made from precision machined aluminum and is black anodized. It includes a brass compression ring that clamps around the inserted eyepiece or accessory. Because the set-screw does not come in direct contact with your eyepiece or diagonal, their barrel will not be scratched or dented. The inside surface of this tube is black-matted to enhance contrast by reducing stray light reflections and is threaded to accept standard 2" telescope filters. 2" barrel is smooth-sided.

Total length = 70mm (2.76"), Extension provided = 35mm (1.38"), Weight = 3.6 oz.

      I needed the Blue Fireball 2" Eyepiece Extension Tube with 35mm extension when I changed focusers on my C80ED. It fit like a glove and does the job perfectly. It is a very well made product, but doesn't cost a small fortune.

      5.0 great accessory for a mak-newt

      Pros:

      Cons:

      Comments:

      most mak-newts are really designed for imaging - the focuser does not have enough out-travel for many eyepieces, especially 2” eyepieces. If your mak-newt did not come with a focus tube extender, this one is just what you need.

      Cons:

      Not much to say other than this worked well to establish the correct focal length to support the change from a 1.25" to 2" focuser in my Astroview 6 OTA.

      I use it to achieve focus with a 2" EP in a Crayford focuser on a f/6 dobsonian. Works great. Quality construction and finish. I wish BFB made one with 20-25mm extension as well.

      Pros:

      Well Made,Light Weight

      Cons:

      Comments:

      The Blue Fireball 80 mm. extension tube replaced three shorter extension tubes I'd been using. This was necessary for imaging with a DSLR camera body and a 2X power tele-extender lens. Now I only have one connection to worry about, and the two thumbscrews are a big advantage.

      5.0 80mm Extension Tube with Brass Compression Ring

      Pros:

      Quality Construction

      Cons:

      Heavy

      Comments:

      Some cameras like my Sony Alpha 6000 need an extension tube to get prime focus. The length of the extension tube depends on the focal length of the telescope and camera combination. The fact that the Fireball Extension Tube comes in 3 lengths if very helpful. There are two large thumbscrews and a brass compression ring that won't make screw marks on you camera adapter. This is a quality product that's much better than the last one I had.

      5.0 Another great tube from Blue Fireball

      Pros:

      Compact,Strong Construction,Easy to Use

      Cons:

      Comments:

      I bought this extension tube as I needed more back focus in order to use a focal extender I had purchased. I had a 40mm Blue Fireball I had previously used but it was unable to provide enough back focus. This 80mm extension tube did the job well. The tube is completely black with threads to accept filters or other accessories. It has a compression ring that is tightened with two screws that uniformly tighten to any accessory inserted into the tube without the problem of leaving screw marks.

      I would definitely recommend any Blue Fireball extension tube.

      I purchased the Blue Fireball 80mm extension to use with my Williams Optics 90 mm Megrez telescope when doing astrophotography with my SBIG 8300C camera. The 80mm extension provided the exact amount of extension to achieve focus with the SBIG 8300C when not using the OAG or filter wheel.

      The dual set screws and brass clamping ring result in secure attachment of the camera to the scope.

      I am very pleased with this accessory.

      Easy to Use,Accurate,Strong Construction

      Cons:

      Comments:

      I bought this after taking delivery of a William Optics ZenithStar 71 ED refractor and discovering that it would not come to focus with a DSLR camera attached. They assume you will use a 2" star diagonal with eyepieces, which generally takes up about 80 mm of back focus. Live and learn. In any case, this well - made extension tube worked like a charm to bring my camera to focus.

      5.0 Ordered Sat night. Arrived Monday Morning

      Pros:

      Lightweight,Easy to Use,Strong Construction,Accurate

      Cons:

      Comments:

      I needed to focus on close (30 yds.) objects needing to extend the focus mechanism. This extension tube is perfect.
      It has a brass tightening band inside tube where eye piece fits. It keeps tension screws from damaging tubes.
      Fit and finish is perfect.
      Plastic caps for both ends of tube.
      1.25 adapter ring is excellent fit and finish.
      **** Oh, and don't forget Agena customer service. I ordered at 11:15PM on a Saturday night and the unit was delivered (by US MAIL) on Monday morning @ 10:30AM! That's the best delivery service I've EVER had, close to what my pizza man does on his worst day.

      5.0 High Quality at a Good Price!

      Pros:

      Strong Construction,Accurate,Easy to Use,Lightweight

      Cons:

      None

      Comments:

      I have several telescopes and a wide variety of eyepieces. Often, a longer focal length eyepiece will need extra focal travel to achieve a perfect focus. I always add a 35mm extension when building up the "business end". It keeps me from fooling around in the dark when I decide to go with less magnification and a wider FOV eyepiece.

      These Blue Fireball extensions are very well built and serve the function very well. Nicely machined with large thumbscrews, they are a pleasure to install and use.

      Pros:

      Lightweight,Accurate,Strong Construction

      Cons:

      Comments:

      This extension tube was needed because I made an innocent error in calculating the position of the focal plane when I was designing my Newtonian reflector. It was easier to add a small amount of back focus with the extension tube than to reposition either mirror. This extension tube is nicely finished with a compression ring and large thumbscrew to grip typically heavy wide-angle 2" eyepieces.

      Cons:

      Comments:

      Actually purchased this to use as a 2" filter holder in the optical train, and it works very well for that. It even has a brass compression ring to protect your eyepieces/ equipment. All parts are finely machined and well finished for excellent precision and function. One of the rare great values in astro equipment, well worth every penny.

      Pros:

      Compact,Accurate,Easy to Use,Strong Construction,Lightweight

      Cons:

      Comments:

      I purchased this extension tube for my new 80mm Lunt ED refractor to use on top of my C-14. I am using 20mm to 40 mm 2" eyepieces to include the 30mm ES 82 degree, 20mm ES 100 and 40mm MK-70. The Blue Fireball Extension is of high quality black anodized construction (inside and out) with brass compression ring and two finger screws for tightening. The extension tube is machined well and holds well in the focuser and the oculars hold well in the extension. I would highly recommend this unit as it fulfills its purpose very well.

      Nice extension. Fast delivery and as usual no complaints with Agena. When looking for a product for my Astronomy needs I normally check to see if Agena stocks it.

      Strong Construction,Easy to Use,Extra Set Screw,Lightweight

      Cons:

      Comments:

      This one of the few extension tubes I've seen that has all of the best features big-name competitors have in one item, such as light weight, rugged build, brass compression ring, and stepped mounting tube. It has a second optional set screw, which is a nice touch. It helps to center the eyepiece and further prevents marring the tube. The price is competitive, being much lower than many competitors.

      Comments:

      My Orion XT10 did not have sufficient back travel for a number of my 2" eyepieces. The 35mm extension adds just enough distance so I can use my 13mm, 8mm, and 4.7 wide angles in 2" mode.

      The Fireball 2" extension is perfect when you need more back focus for your CCD camera on DSLR. Simple to use (you just slide it in your focuser) and robust. There is no slippage or play and it will old even the heaviest camera out there.

      Pros:

      Strong Construction,Easy to Use,Compact,Lightweight

      Cons:

      Comments:

      I use both the 35 and 50mm extension tubes with my refractors which are very useful when using EPs that require substantial backfocus (eg Vixen LVWs). Using the extensions provides the ability to focus on very close-up terrestrial targets that would otherwise be too close to obtain focus without the extension. And having the brass compression ring puts them in with higher end ewuipment.

      5.0 Blue Fireball 2" Extensions

      Pros:

      Strong Construction,Accurate

      Cons:

      Comments:

      I was very impressed by the quality of this extension. It's robust construction makes it one component that I don't worry about in the focusing train of my homebuilt cassegrain telescopes.

      4.0 Good product

      Pros:

      Strong Construction,Clumping ring

      Cons:

      None

      Comments:

      It's very useful thing when you've got a short focuser. Clamping ring doesn't scratch Your eyepiece.

      Very robust,Strong Construction,Accurate

      Cons:

      Comments:

      Was looking for an extension to bring my DSLR to focus from a 2 inch focuser. Very good build quality and not to heavy. Very stout with no sag at all. I especially like the dual set screws that really locks it in place.

      5.0 Blue Fireball To The Rescue!

      Pros:

      Quality Lenses,Strong Construction,Well Made

      Cons:

      None really

      Comments:

      I needed some extra focus travel for my 2 inch Orion 40mm Ultra Scan EP, when using it with my new XT8i Dobsonian scope. The Blue Fireball came on a high recommendation from a friend, so I tried it. The fit is excellent, and it really solved the problem.

      Cons:

      Comments:

      Light weight and well made with tight tolerances, the only suggestion for improvement is to make the thumbscrew a larger diameter keeping it low profile. That would make it easier to secure eyepieces more securely.

      Cons:

      Comments:

      This a great solid extension tube. Some 2" eyepieces will not focus in my 8 inch dob. This extension fits the bill perfectly. The only complaint is the set screw is very small. Other than that I am pleased with the product.

      Cons:

      Comments:

      A necessity for astro imaging when not using a star diagonal on most refractors. Handy to have in your kit at star parties, too! Would love to see one with 3 thumb screws, for use with heavy gear.

      4.0 Quality Extension Tube

      Pros:

      Strong Construction

      Cons:

      Comments:

      I'm reviewing the 80mm variety here. As an owner of an APO refractor with only 70mm of outward focuser travel, I sometimes have issues coming to focus with the myriad of accessories I'm known to attach to the scope - two binoviewers, (each with different focal points), OCS Optical Corrector, 2" EP, 1.25" EP's, 2" ED Barlow, DSLR + adaptor, etc...

      This unit gives me some additional configurations that wouldn't have been possible without it. One simple config that comes to mind is increasing my GSO's 2" ED barlow's 2x magnification power to somewhere closer to 3x by putting the barlow directly into the diagonal and then the extension tube into the top of the barlow, and then the EP into the top of the extension tube. It makes for a very odd looking and somewhat precarious configuration but gets the desired magnification result while still coming to focus. Just make sure to tighten everything down since the further the EP is from the focuser tube, the easier it is to swivel on its own and try to find a resting spot on the ground (to the possible detriment of your equipment!)

      The unit itself is solid aluminum with great black anodizing. The compression ring holder and recessed saftey groove in the barrel were both requirements for me. I deducted one star from my rating due to it only having one set screw for its compression ring holder instead of two which would have given me more confidence in securely holding some heavy accessories. Overall its a solid addition to my equipment arsenal.

      Pros:

      Economical,Strong Construction

      Cons:

      Comments:

      I needed an extension tube for my 8mm Ethos on my AT80LE ED80 scope, since it wouldn't come to focus without it. I also wanted some 2" extensions for my astrophotography setup to provide clearance for the camera cooler I'd added to my DSLR. These fit the bill at a great price. I really wanted the safety ring on the barrel as I'd had problems with adapters in the past where my camera fell off due to thumbscrews working loose. I also like the brass compression ring as opposed to the single point contact of a screw. The only thing I'd like to see on this that would make it better would be a second thumbscrew on the compression ring. Still, overall a great piece for the price.

      Pros:

      Nice Finish,Accurate,Strong Construction,Compact

      Cons:

      Safety under cut

      Comments:

      Great product. I have all three sizes (35-50-80mm) and love the construction and finish on these extensions. I don't particularly like the safety undercut on the nose piece, but for the average user this won't be a problem at all. The EP tightening knob is a nice size and comfortable to use even with gloves on.

      Cons:

      Comments:

      I needed an extension for a 2" focuser on a recently acquired 120mm f/8.3 refractor that had been shortened for use with binoviewers. The Blue Fireball was a perfect solution with tight tolerances and a brass compression ring. It is easily the equal of some much more expensive extension tubes.

      4.0 Add 35mm to your available out-focus

      Pros:

      Strong Construction,Accurate

      Cons:

      Comments:

      This adapter is made of precision machined aluminum with a black anodize finish. It has a brass compression sleeve, and threads on the inside to cut reflections. The threading also allows for attaching a 2" filter. It adds 35mm to the focus out distance, good for scopes meant for use with diagonals but you want to use in straight-through mode. My only suggestion would be to add a second thumbscrew to grip big 2" eyepieces a little more securely.

      Cons:

      Comments:

      Great bang for the buck.

      The only improvement I can think of is that the thumbscrew could be a bit larger. If it weren't for the fact that my 1.25" adapter is a helical compression type, which means that I twist a ring at top in order to clamp the 1.25" eyepiece, I don't think this wouldn't be an issue at all. It isn't that big of a deal but if the thumbscrew were bigger it would be easier to tighten down on the 1.25" adapter so it wouldn't twist in the extension barrel when I change 1.25" eyepieces.

      Pros:

      Quality Construction,Nice Finish,Strong Construction

      Cons:

      Can use bigger thumbscrew

      Comments:

      Provides that additional back focus, often needed. Eliminates the need for a diagonal when doing eyepiece projection imaging. This allows the imaging equipment to lined up straight through, minimizing balance problems and reducing rotational strain on clamp screws. The only negative... could use a larger thumb screw, but is slotted for use with a screw driver.

      With only days remaining until my 600 mile trip to the Nebraska Star Party, I found I needed a tube extension in order to reach focus with my new Crayford focuser. I was very pleasantly surprised by the high quality of the piece, it's light weight, and very smooth, quality finish. The cost was less than half of the cost of a similar item from some of the "big name" companies.

      This extension is a perfect fit for my new GSO dual-speed focuser. It's nice to have a compression ring and know that it won't damage any of my eyepieces. On the other hand, an eyepiece with an undercut will get caught on the brass ring which can, at times, be annoying. Overall great product.

      5.0 2" 50mm Extension

      Pros:

      High quality fit finish,Low cost

      Cons:

      Issue with filter thread

      Comments:

      I bought this extension for use with the GSO Low Profile Crayford focuser. The low profile focuser is great for imaging, but is a little short for some eyepieces in my telescope. The 50mm extension fixes that problem. It allows all of my eyepieces to comfortably come into focus while using the low profile focuser.

      The 2" barrel fits into the focuser without excess play. The brass compression ring holds eyepieces in place adequately even though it only has one thumb screw. It has a safety groove cut into it to avoid falling out of the focuser. The extension tube is threaded for filters, but the 2" filter threads did not mate well with my Orion Skyglow filter (but can engage enough to be used). There are known issues with not everyone using the same threads for astronomical filters.

      The inside of the tube is black and machined with grooves to reduce reflected light. This item is of good quality and available at a much lower price than alternatives.

      5.0 Amazing piece - 50mm Extension

      Pros:

      Compact,Strong Construction,Accurate

      Cons:

      Comments:

      I bought the extender for my Equinox 80ED because its focuser tube is too short for me to reach focus with my Canon 300D. The color and build really match my 80ED! The build quality is excellent, the weight is light. Before I placed my order, I was not sure about the product quality; but after buying the piece, it totally changes my mind.

      5.0 Perfect Hyperion 2" adapter

      Pros:

      Strong Construction,Safe,Accurate

      Cons:

      None

      Comments:

      I have Baader Hyperions and this adapter allows me to use the 2" section of EP and maintain perfect focus in my 10" Dob. I now can use 1 1/4"filters on EP and 2" filters on the extension without interference unlike with the other set-up. If you have used the 1 1/4" to hold this heavy eyepiece when you have a 2" focuser, feel more secure and get this adapter!

      5.0 2" Extension

      Pros:

      Compression Ring,Lightweight,Great Price,Strong Construction

      Cons:

      No cons on this product

      Comments:

      I received my 35mm 2" extension. I opened the box and was pleasantly surprised at the quality of the piece. My main reason for purchasing the extension was the fact that I have a low profile GSO crayford focuser and in using my Hyperion 13mm eyepiece in the 2" format I didn't have enough outward travel to bring it to focus. The extension is very well made of all aluminum, and is extremely light as to not add much unnecessary weight to the eyepiece chain. The extension has a brass compression ring so it will not damage the barrel of my eyepieces and it holds them really snug. All in all for the price I am extremely happy with the look, feel and quality of this extension. For [$] it's a deal! I recommend the extensions to everyone in need of one!
