Manufacturer Description

Here is a very versatile adapter from Blue Fireball that can be used for prime focus and fixed or variable eyepiece projection photography with your telescope.

Separate the two parts and the smaller lower barrel by itself is a standard 1.25" Prime Focus T-adapter. Insert the 1.25" barrel into your diagonal or telescope, attach your D/SLR camera to the male T-thread (via a T-ring that is specific to your camera; not included), and you are ready to take photos as prime focus with your telescope or spotting scope. In this set-up, the optical chain will be: 

Telescope/Diagonal > Prime Focus T-adapter> T-ring > D/SLR camera

Or you can use the complete adapter for fixed/variable eyepiece projection photography. Just insert the 1.25" barrel of the adapter into your diagonal or telescope, and then insert an appropriate eyepiece into the upper barrel. Your camera can then be positioned to shoot the magnified image created by the eyepiece. Again, the camera attaches to the male T-thread at the top of the adapter with an appropriate T-ring for your camera that you provide. In this set-up, the optical chain will be:
 
Telescope/Diagonal > Eyepiece Projection T-adapter (adjust length as desired) > 1.25" Eyepiece > T-ring > D/SLR camera

But that is not all. The magnification in the image you shoot depends on the distance between the top of the inserted eyepiece and the camera. This combination eyepiece camera adapter has a sliding barrel design that allows variable projection distances for eyepiece projection photography. This eliminates the need to change eyepieces when different magnification or additional projection enlargement is desired. All you need to do is to slide the outermost barrel away from or towards the telescope and the projection magnification increases or decreases. This additional projection range is particularly useful in high-resolution Lunar / Planetary photography. Of course, you can still change your 1.25" eyepieces to gain an even larger range of magnifications.

You will be able to use many, but not all, 1.25" eyepieces with this adapter. The adapter barrel can accept 1.25" eyepieces up to 38.5mm (1.52") in maximum outside diameter. The length of the upper barrel of the eyepiece (above the eyepiece shoulder, excluding the lower 1.25" barrel) cannot exceed 72mm (2.83") in the shortest setting position of the adapter or 106mm (4.18") in the longest setting position of the adapter. Please check your eyepiece dimensions before ordering to ensure that it will fit inside the adapter.

The prime focus adapter end is threaded to accept standard 1.25" filters so you can use your favorite photography filters as well. The adapter is precision machined from aluminum and black anodized, and weighs 7.1oz. The total length of the adapter can vary between 118.6mm (4.67") and 152mm (6") depending on the eyepiece used and the projection desired.

The lowermost single silver screw visible in the photos is used to secure the 1.25" eyepiece inserted into the adapter. The two other silver screws are used to lock the sliding barrel in place over the inner barrel.
 
The use of this adapter is not limited to D/SLR cameras. It can also be used to image with webcams and video cameras. For this, you will need to attach your webcam to the male T-thread on the adapter via a webcam-to-T thread adapter. Similarly, you can connect a video camera via a C mount-to-T thread adapter. This adapter cannot be used with point-and-shoot cameras.

      5.0 Nice Solid Product

      Pros:

      Cons:

      Comments:

      This is a very solid product, which holds firmly once the screws are set. No wiggle here. I use Celestron Omni XLT plossies for projection, which fit well inside the barrel with very little play, and which fit snugly once the eyepiece screws is tightened. Overall a well machined and good adapter.

      The fireball is so well made, I may just buy two so I can display one on my wall. It’s solid, precise threads, overall an excellent product!

      5.0 Only Way to Image with a PST

      Pros:

      Cons:

      Comments:

      This device made it possible to eyepiece projection images with the Coronado PST and Skyrys 236M camera. You will also need a Blue Fireball V-02 "T to C" adapter.

      4.0 Very Good, but...

      Pros:

      Cons:

      Comments:

      Needs some improvement. Build quality is very good as is functionality. Eyepiece support however- not so much.The eyepiece holder tube is just a hair too small. It is really only acquire to hold an eyepiece that is. Couple millimeters larger than the barrel. You are looking at orthodontist or standard plossl at focal lengths 26 mm and below. I have a couple gso plossl's and the 9 mm and a 21 mm Keller I had laying around d work great, but it is just a hair too small for the gso 32. Just a couple mm more and many more eyepieces would be viable. I also have a 6mm agena swa(I think these are the same as Orion starguider) that fits fine. I can understand that it is impractical to make it so my Meade 5.5 has would fit, but I was expecting the 32mm gso plossl's to work, but it is just a mm of so too small.

      5.0 Very impressive

      Pros:

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

      Cons:

      Comments:

      Was looking for a good adpater for eyepiece projection. The description of this was just what I was looking for. My only concern as other expressed was eyepieces fitting inside. This turned out to not be an issue at all. The construction is very good, the variable focla length adjustment makes it great, I was worried about flex with it extended. I have used it on 32mm, 25mm, and 12mm eyepieces and have provided great images of Jupiter and Saturn. Still trying to get the right combination for some of the brighter DSO, but that is a challenege of my lack of knowledge, not this product. If you want a great cheap way to do eyepiece projection then you can't go wrong with this. The eyepiece arrived in only 3 days so that was impressive shipping, so I recommend this, and with the fast shipping you will have it fast to see how easy this is.

      5.0 Better than I expected.

      Pros:

      Easy to Use,Strong Construction

      Cons:

      Comments:

      Been doing prime focus with a Celestron t-adapter. Was good for DSO, but for planets there was very little maginifcation. This was just what I needed. The shipping was very fast, had it in 2 days. The construction is better then I thought it would be, the t-ring screwed right in perfectly, the eyepieces all fit in with no issues, even the 6mm with the rubber eye guard. I was concerned about flex in the assembly with it fully extended, this also proved to be a non-issue, the whole assembly is extremly strong. I have seen a drastic improvement in the quality of the images I take instantly. I was researching this type of photography and all I can say about it is they make it way harder then it sounds, this adapter makes it all so simple, drop in your eyepiece, fasten it all to the camera and telescope, and your off and running. Only drawbacks I see in the whole process, make sure your alignment is perfect, and focusing can be a bit tricky at higher magnifications. But this adapter is perfect and I see no reason to spend $80-100 when this is so good for so much less.

      Pros:

      Strong Construction,Easy to Use,Lightweight

      Cons:

      Comments:

      Great product. Tried a lot of cheap chinese t-mounts and fittings before with a lot of bad threads, poor finishes, etc., and was expecting something similar. What a surprise, clean threads, perfect finish, works great. Excelent product overall.

      5.0 Very versatile

      Pros:

      Strong Construction,Compact,Accurate

      Cons:

      Comments:

      This is a really universal adapter. Not only it does 1.25", I take out 2 screws for the bottom barrel and it becomes a 2" adapter which fits right into my 2" crayford focuser ( although little bit longer than the regular 2" adapter ). I was playing with it because of cloudy weather and did some really macro photography with my 25mm eyepiece, like zooming into snowflakes.

      4.0 Very nice product

      Pros:

      Strong Construction,Compact,Accurate

      Cons:

      Difficult To Focus,Unstable

      Comments:

      With this adapter you can do very nice photos at Moon and at other bright celestial objects. The eyepieces fits perfectly inside the adapter and you can reach very high magnifications. It's a bit difficult to focus, but if you have live view in your camera it will be easier. I use the adapter to join my camera (pentax k-x) to my 700mm telescope and it works pretty well. Since my camera is heavy, the telescope become a bit unstable.
