OK, I am going to revise my opinion of the 150mm Mak on a Polaris GEM.

I recently fitted a 2" Crayford focuser and 2" diagonal to the back of my Orion, and when used with a heavy eyepiece (e.g Vixen LVW in a 1.25"-to-2" convertor) seems to have pushed it over the edge when riding on my Polaris. It is fine at mags up to 25-30x/inch, but above that I am less tolerant of the vibration.

The Crayford is a valuable addition as I no-longer have to deal with the infuriating mirror shift. In order to retain the steadiness I have previously observed with my Orion/Polaris combo, I will replace the Crayford with a 1.25" Borg helical.

It took 10 lbs of 2.5 lb ($2.00/ea) barbell weights in addition to the original 6.5 lb counterweight to balance my iOptron 150 Mak on the Vixen Polaris. Used Lowes purchased 16mm nuts and washers to secure them.
