I have got the 0.8 FR with my SV80 and while I do like the faster/wider set-up I do notice stars in the corners to be less than perfect to put it lightly.

I have been considering other flatteners and/or reducers. I see now that there is the SFF3-80. I haven't seen many examples of images from this flattener. I'd like something that will give me pinpoint stars to the edges of crop frame sensors or better.

Hello Dan, the SFF3-80 is the flattener you want to use for imaging with your camera. We think it'll give you round stars to the edge of your frame. If you have further questions, please call us at Stellarvue and we can explain further. Thank you for choosing Stellarvue, we appreciate your passion and loyalty.
