NGC7009SaturnNeb_Roy_3X500s_Sep_4_2013_XCubeRtLog_Blowup
NGC7009 Saturn Nebula taken with Royce 10in f6 Newtonian at Baader MPCC Coma Corrector with Orion Starshoot Pro V1 Camera - Schneider 486 UVIR Filter. 2013:09:07 17:07:01 TIFF Image File by GateSoftware. Scope mounted on Orion Atlas EQ/G mount, with PEC correction and autoguiding with an Orion Starshoot Autoguider on a Lumicon short Off-Axis Guider (OAG). A stack of 8 x 500 sec exposures. Luminance compressed by the log(cube root) functions. You can see why early observers thought they were looking at a distant version of Saturn!
