What's the best focal reducer for RC8? My camera is Canon T5 modified with APS-C sensor.
                  I only used my RC8 for 2 nights. First night only camera and telescope. Second night  I used with flattener 1.0x for refractors and the field improved a lot.
                  Thanks!

I just began using the Teleskop Services 2" flattener for RC scopes.  It seems to work well as I am happy with the stars in the corners.  I chose it over others because of the long distance between the flattener and sensor.  With others, I would not have been able to fit my existing OAG and filter wheel in the required spacing.

HTH,
Ron

This seems to be the most common focal reducer used by other RC 8 users. I just started using it.
