I did some research on mirror flop and I'm not impressed.

There seems to be a lot of work and expense in working around it if it exists and seems to be inherent in this type of scope, from minimal to severe.

I do like reflectors for their light gathering ability, I might just get a Skywatcher SW252 and upgrade the focuser and motorize it. Then if I need to I can use EQMOSAIC but I think the SW252 is f4.7 anyway. Whaddaya reckon??
