Jun 24, 2017Fireball Spacer
Pros: Cons: Comments:Excellent and works beautifully. One thing with these little spacers is to try not to overtighten. They tend to lock up.

Mar 25, 2016Well made and a perfect fit
Pros:Accurate,Lightweight,Easy to Use,Strong Construction
Cons: Comments:This adapter extends a T-ring threaded assembly by 30mm. It is well made and works exactly as you would expect.

Feb 4, 2016Great fit and finish
Pros:Strong Construction,Well Machined
Cons: Comments:I purchased this to use with a 2" to T-thread adapter on my 4" f/5 short tube refractor. This combination allows my DSLR and autoguide camera to focus without having a diagonal in the light path. The anodizing is well done with now flaws, and the threading is smooth, with a perfect fit. Most importantly, Agena are the only supplier of such an item that I could easily find.

Jun 26, 2015Good Quality Spacer
Pros:Accurate,Strong Construction,Lightweight,Easy to Use
Cons: Comments:I have quite a few Blue Fireball adapters and spacer and they are all of the same high quality. A lot of spacers are made from cheap aluminium with threads that strip and chip as soon as you use them. Blue Firebll are high quality with smooth threads.

Mar 30, 2015Be Careful
Pros: Cons: Comments:I needed a small amount of increased back focal length between a ccd camera frame and another adapter. This spacer did not work; not because of the spacing but because there was only 1 full thread on the male side of the spacer and that was not enough to engage the first thread on the camera body. There are only about 2 threads on the female side. In my case, both threaded ends could have had up to 6 full threads and still accomplished the 2mm spacing while adding strength to the connection. As it is, it cannot be used.

Feb 20, 2015Be careful with the thread length
Pros:Avid Adventurer
Cons:Avid Adventurer
Comments:It is my fault that I didn't check the female thread length so that my mating component cannot thread in completely, which makes the spacing not correct. Be careful on that!

Feb 24, 2012Work as advertised but think think...
Pros:Accurate,Easy to Use
Cons: Comments:Agena seems to be the best place to order these spacer rings. I used them to get the correct spacing for a field flattener.
Bottom Line: Would you recommend this item? Yes
One thing to note - think about how to reach your correct spacing before ordering. I ordered a large one and a small one. The issue I ran into was that the smaller rings have very little thread on them due to their size. I would have been better off buying (for example) a 7mm and an 8mm to reach 15mm instead of say a 13mm and a 2mm.
I made this mistake the first time and Agena allowed me to swap out for the correct setup easily without any kind of hassle.
I always recommend Agena Astro at our local astronomy club.This review was provided courtesy of AgenaAstro.com
Oct 30, 2011One of those hard to find accessories
Pros:Lightweight,Strong Construction,Compact,Simple,Easy to Use
Cons: Comments:I needed a thin T spacer ring to assist with the use of an Off Axis Guider. The 7.5mm I already had was too long, but the Blue Fireball in 3mm and also 4.5mm fitted the requirement perfectly. Cost effective as well. Very happy.

May 28, 2011Best spacers on the market!
Pros:Ideal,Accurate,Excellent construction
Cons: Comments:I tried a lot of spacers from others but none matched the accuracy and construction of the Blue Fireball...highly recommended. Two thumbs up for Agenaastro.

May 2, 2010[...]
Pros:Accurate
Cons: Comments:I needed T-thread spacers to achieve the correct separation between a field flattner/focal reducer and my CCD camera. The product descriptions were accurate and I got exactly what I needed.

May 1, 2010Excellent craftsmanship
Pros:Accurate,Strong Construction,Compact
Cons: Comments:I bought the 40mm spacer ring as an extension tube for astro photography (eyepiece projection) use. It works beautifully, it is a well crafted piece and since it is all black inside, there are no unwanted reflections.
Bottom Line: Would you recommend this item? YesThis review was provided courtesy of AgenaAstro.com

Jun 15, 2009Solid, but inaccurate
Pros: Cons: Comments:I purchased this to gain proper spacing between the Baader MPCC and a CCD camera. The problem with this item is that although it is supposed to give 3mm spacing, such a narrow body does not allow the "male" threads of the MPCC to screw in all the way. Thus, in the end, the ring actually ends up extending the imaging distance by about 7mm. On the positive side, the finish of this piece is exceptional, the threads are smooth. I also purchased the 10mm and the 20mm versions, and am very pleased with them. So, the quality of this piece (and of all the Blue Fireball spacers that I bought) is great; just be aware that with the 3mm version, you will probably end up with more than 3mm of spacing unless what you are attaching has a very shallow male thread.
Bottom Line: Would you recommend this item? YesThis review was provided courtesy of AgenaAstro.com
