My old club back in NZ has a 150mm Mak as a loaner scope on an EQ5 and tho it takes a long time to cool the views when it has are very nice , almost as good as my Chromocor'd 6inch Saxon for sharpness and overall aesthetics of the image , a nice scope if you give it at least 1-2 hours to cool before using . Or leave it in the shed
.
A vote for the Mak's as well .

ps. my C9.25 would better either on all objects .
