Finally got my dodgy EQ6 guiding decent last night. Gave it a challenge - C925 with 6.3 reducer/flattener fitted. Seeing was good, not great but still impressed with how the big SCT performed, and my DEC was always around 0.3rms. I still have some work to do on the RA which was around 0.6rms but spikes going to 2 or even 4 occasionally, which the DEC didn't have.

ASI533 and 300 sec exposures. 200 mins total.

Lots and lots of wee galaxies there too

Again, lighter and darker background. Neither clipped. Which to you prefer  ? I still like darker myself.
