I have had a HyperStar for my C8 for several years and I love the fast, wide view but I have been pretty lazy lately and haven't wanted to muck around on the front of the scope...so I decided to try a small fast refractor. I got an AT60ED with the reducer/flattener. It is f4.8 with a whopping 276 arc-min view when used with my 294MC Pro. I really wanted it for sweeping views of the milky way, the Cygnus loop, etc.
Here is a shot from last night of the Small Sagittarius Star Cloud. So much to look at and it was fantastic to view on my large flat screen at full resolution. Mesmerizing and so much to look at.
I had to butcher it and shrink it to upload so just imagine at full resolution!
The AT60 is tiny but really performs. With the reducer/flattener, stars are great all the way to the edge. I never really appreciated good star quality until now. My C8 never gives perfectly sharp stars like this little refractor. And you can insert a 2" filter in the imaging train.
SharpCap RAW16, gain 316, Exp 27 seconds. Total time ~5 minutes. Darks but no flats. 294 MC with IDAS LPS P2.
The short focal length also makes it really easy to do a long exposure. I didn't even polar align or balance my mount this time.
