i will get a image up as soon as the rain stops for long enough for me to snap one. As for some more info. the focuser on the primary scope is a crayford one, and on the refractor it is a rack an pinon. The guide scope is piggybacking. The mounting plate and guide plate are both losmandy and the rings on the primary are also quite solid construction. The guide scope is held by rings with plastic screws (should i change to metal ones or just make sure the plastic ones are tight enough). As for polar alignement i have done a fairly decent (well i believe so) drift alignement and can leave it for 30 mins with minimal drift (not noticable to my eye) only drift i see is PEC related on the east-west axis (as i beleive a polar misalignment would result in north south drift i have been led to believe). Also on closer inspection at high zoom you can see slight trailing in the stars of subs from the DSLR.
