Scope: FSQ-106N
Camera: SBIG STL-11000, -20°
Comments: This is my first light image from Blue Sky Observatory (BSO), my remote observatory (Sierra-Remote Observatories - ). I share a Paramount ME, FSQ-106N, SBIG STL-11000, Astrodon LRGBHa filters and a Takometer Rotator, FS-60C guidescope, and SBIG RGH with Steve Mandel. This was taken over multiple weekends on generator power as we wait on our permanent power connection. The 2nd or 3rd night we were fully functional, the seeing dropped under 1 arcsec ( according to our SBIG seeing monitor) !!! This image was taken while I was still tweaking the TPoint model and learning how to calibrate the Takometer. Now everything has settled down and startup and shutdown is in a nice routine.
