Focal Reducer - Should I or Should I not?
I've pulled the trigger on an ASKAR FRA 400 F/5.6 72mm refractor and I'm unsure as to whether I should lash out and invest in a focal reducer.
ASKAR has a 0.7X flattener/reducer which shortens the focal length from 400mm to 280mm and the focal ratio from f/5.6 to f/3.9 which retails for over $400.
Am I going to gain much by going down this path? Most of my imaging is carried out from my Bortle 6 - 7 backyard in Brisbane and I normally shoot with a guided ASI533 MC Pro cooled camera and an Optolong L Extreme dual band filter.
Comments/suggestions please.
