Celestron EdgeHD 1100 and the QSI-583wsg

This gallery is for displaying images produced using the 11" Celestron EdgeHD telescope and the QSI 583wsg CCD camera equipped with Astrodon Tru-Balance Generation 2 E-Series - LRGB 1.25". The QSI 583wsg has an internal filter wheel and an integrated off-axis guider, both of which eliminate crucial sources of flexure.

The mount is a Losmandy G11 with the Gemini system which has been upgraded with Maxon motors and the Ovision precision worm assembly on both the RA and DEC axes. Currently, the uncorrected periodic error is +/- 3.5 arc-seconds. Autoguiding is performed with Dr. Craig Stark's PHD Guiding autoguiding software and the Starlight Xpress Lodestar autoguider attached to the integrated guideport of the camera. Processing is performed with a combination of Mike Unsold's ImagesPlus - Automatic Image Set Processing and Craig Stark's Nebulosity2.

Optec Lepus .62x focal reducer yielding 1848mm, f/6.6 and an image scale of 0.60 arc-seconds/pixel when unbinned.
