CSW! It is interesting you say you don't want to pursue MMA but you are talking about mixing your martial arts. :) Maybe you mean you don't want to fight in a cage for money?
Note that the gold reflector will shift the colour temperature of everything it hits, so if you're photographing a model wearing white, and that white has to look white in the final picture, you're just going to have to put things back the way they were in post anyway
The main problem involving reflector telescopes is the spherical aberration, which is caused by the focal length not being the same for wider parts of the mirror. This can be corrected by using parabolic mirrors instead of spherical mirrors. What is the difference between refractor and reflector telescopes?
