Yes really? Just wan't to say I received my cgem, free sheeping from astronomics, 1 (one) day after ordering! They've always been fast, but here that was the fastest.
RA and DEC are butter smooth. The head is heavy. I could have balanced my c9.25 with a single 11lb counterweight, because it came with the long shaft, but i prefered to put an additional 8lb counterweight from my cg5 instead. Anyway, I easily balanced the ota in both axis.
The hard part was to replace the vixen-style dovetail of the C9.25 by a losmandy plate, which put the ota about 2" away from the saddle. Also the bottom of the losmandy 'dovetail' (i originally bought it as part of a piggyback ring system, so i am not sure it qualifies as a dovetail) does not touch the bottom of the saddle, and therfore the dovetail is hold only by the sides. The OTA is not easy to install, but i couldn't find any new D dovetail since my C9 was the 'old style'. Anyhow, I could still put the ota on the mount and there we go.
I Used it first with an old jump start battery, which despite the fact it was not fully charged, didn't cause any error or weird behavior. Then I used the new 5 amps AC celestron powersupply. It worked perfectly.
The mount feels very smooth and very quiet (not noisy at all) during the star align.
I didn't used it much, but I still had time to perform a PolarAlign routine, it rocks! My target seemed pinned on the same pixels of my dsi pro2 at f/10. It probably moved no more than 10 pixels during more than 1 hour.
I have to image more to evaluate all that, but so far it's a huge upgrade from the cg5. I am not disapointed and next steps will be to push the accuracy of the gotos to get small targets (planetary nebulaes) and image them at f20....
