Adapter to use with edge hd 8 reducer and celestron off axis guider
Pros: Cons: Comments:Perfect fit for using it with celestron off axis guider as it replaces the SCT adapter that comes with OAG and connects to the off axis guider body. This adapter helps you to attach a dslr camera and stay in the 105mm back focus with the reducer on it.

Jan 10, 2019Blue Fireball SCT Female Thread to M48 (2" Filter) Male Thread Ad
Pros: Cons: Comments:It does what it says. My only "complaint" - cost. Adapters shouldn't really be more than a few dollars; after all, these are a thin ring of metal with threads. But other than that, works fine.

Nov 2, 2018Perfect adapter
Pros: Cons: Comments:I had searched for this 2” to 48mm adapter for several months and thankfully found it at Agena. Fits the rear cell of my SCT perfectly and allows me to used standard 48mm/42mm extensions along with my Nikon T adapter. Arrived on time and was fairly priced. Precisely milled anodized aluminum should give years of good service.

Jan 30, 2015The bridge between two worlds!
Pros:Easy to Use
Cons:Lightweight Construction
Comments:This little ring is really a bridge between two worlds! A very easy to use, light and well made ring that enables a SCT thread to be converted into a M48 thread. It does the job fine, and although it looks well made, it seems that the threads could be a little bit longer and the metal a bit thicker. It's not very reassuring watching so much thread from the SCT visual back not being used by the ring - it seems that if I accidentally touch the imaging train a bit harder, the ring will break. Of course this is just a feeling... but, so far, so good!

Jan 25, 2014Blue Fireball Adapters
Pros:Good Quality Threads
Cons:Could Have A Thicker Wall
Comments:Astro Imagers have to buy Adapters to make their Image Trains focus. Unfortunately there exists a wide range in the quality of the threads available. This is amplified by short and too thin wall designs. I have scrapped many Adapters that have wedged on too tighly to remove.
Bottom Line: Would you recommend this item? Yes
Blue Fireball are generally good threads just as Edmund Optics sell. Edmund has a very narrow range of Adapters however.
The only problematice adapter that I have bought from Blue Fireball is the M48 1/4" long. The threads on that adapter often will not bottom out, either due to out-of-round condition or due to taper.
It is difficult to thread a short thinwall Part. The fix would be to make the wall thicker. .03" to .04 material added to the wall thickness would help greatly, while not affecting function.
In general, I find Blue Fireball to be good quality at a great price.

Aug 8, 2013Incredibly Useful Accessory
Pros:Accurate,USEFUL,Lightweight,Strong Construction,Compact,Easy to Use
Cons:None
Comments:I really didn't know this line of adaptors existed until I found them at Agena AstroProducts and I can tell you they solved all my problems. I own an 11" SCT and wanted to permanently mount a Lumicon UV Dust Seal Filter and TWO Orion 4-position 2" Filter Selectors between the SCT's Visual Back and the Diagonal. I had to go back and forth between male and female SCT threads and 2" filter threads using 3 adaptors to make it work. I don't know if I will ever be able to disassemble it without issues of not being able to re-separate all of it, but man, what a rig!
