After much waiting,  my final scope has been installed.   This telescope just oozes quality.   I was lucky to receive a mirror with a 1/35 wave RMS.  The Astro-Sitall mirror held focus all night long.  Only a few counts of focus change from 65F down to 32F.   I used this on Friday night for my own private Messier Marathon, and it delivered in strides.   I’m still kickin’ the tires and working out the last few issues, but should be able to get some images off it soon.   Collimation was spot on straight from the factory.   I was able to get ~2 hrs of M106 Lum to test.
