A couple of months ago I acquired an Askar 107PHQ scope, fantastic piece of equipment, love it.
Now I'm thinking of adding the reducer (Askar 0.7x Reducer for Askar 107PHQ / 130PHQ / 151PHQ), however in this case the few reviews are not so positive. There are a few videos on Youtube and one or two online comments, all talking about chromatic aberration and oval stars.
Is there any first hand experience around? At the moment I will use it from the 533MM small format camera, but at some point I plan to go for the big brother, the 2600.
