Been searching for info on the Astromania Field Flattener that I would be using with a Sony A7S and a Stellarvue SV80ST. I do know there might be some vignetting in this combo but not a real concern. Not interested in using a reducer/flatterner at this time and I also have an Astrotech flattener that I will test as well when the scope arrives. Heard good things with the Hotech flattener and even the SFF 3-80. BUT, I am wanting to compare it to the Astromania since the company detail notes that it generates pinpoint stars out to the edge of the frame. A pretty bold statement but if it applies to my application, I would add it to my buy list. It is on Amazon so I can test it and send it back if it is not up to snuff. I am looking for feedback from anyone who has actually used the Astromania flattener.
