Tried to polar align my mount finally and just had issue’s
I’m going to go back out again tonight I hope and try again.
after homing the mount I slewed to Rigel and it was nowhere near where the scope was pointing, it was in the right part of the sky but was many degrees off, this seemed strange, I check my Lat/Long and date/time all where good. went into the TCS control panel and reset all the mount settings and still no good. after several hours and loosing all feeling in my fingertips I gave up for the night and fired up the SBIG ST-i (which I got as a guide camera) and took this shoot. nothing special but at least the camera worked
10 Light Frames @ 90s each and dark subtracted
Quick post here to get up some images I took tonight
Spent some time tonight capturing more images of M45 including some basic color as seen here
All Images were done through the AT10RC with the STL-11000M2 Camera. Images are Binned 2×2
First up is a redo of M45 – The Pleiades This is 6 x 360 second exposers @ -20c + 1 x 360 for Red, Green & Blue Stacked and Aligned in MaximDL then touched up In Photoshope CS 4
Next is a redo of M37, again more exposer time but no color on this one This is 5 x 360 second exposers @ -20c. Stacked and Aligned in MaximDL then touched up In Photoshope CS 4
Finally Here is something new M33 – “The Triangulum Galaxy” This is 6 x 180 second exposers @ -20c. Stacked and Aligned in MaximDL then touched up In Photoshope CS 4

After spending hours workin on Polar Alignment, PEC and pointing on the Paramount I finally settled in to do some basic imaging. the following are 5-6 minute, unguided exposures thru the AT10RC/STL-11000M
Pixel scale is .92arc/sec per pixel measured through PemPro. Tracking was great but polar alignment is still not quite right.
I just spent a nice cold night out measuring the Periodic Error on my Paramount ME and can say I’m very happy
Assuming I did everything correct I measured my PE at +1.1/-1.5 or just shy of 3 arc/sec peak to peak (2.6arc/sec) and PemPro Shows it can get this down to +0.4/-0.5 arc/sec
I measured for 12 Work Cycles with 1 second exposuser on my AT10RC with a STL-11000M2 Camera MaximDL was driving the Camera and of course TheSkyX the Mount.
