      4.0 Blue 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.

      5.0 Perfect 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.

      4.0 The 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!

      4.0 Blue 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.

      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.

      I am a Mechanical Engineer by Trade, with over 40 years of work experience in Machine Tool.

      5.0 Incredibly 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!
