(slight reprocess and rotation to better see "the wizard") Description from NASA APOD: Located only 8,000 light years away, the Wizard nebula, pictured above, surrounds developing open star cluster NGC 7380. Visually, the interplay of stars, gas, and dust has created a shape that appears to some like a fictional medieval sorcerer. The active star forming region spans 100 about light years, making it appear larger than the angular extent of the Moon. The Wizard Nebula can be located with a small telescope toward the constellation of the King of Aethiopia (Cepheus). Although the nebula may last only a few million years, some of the stars being formed may outlive our Sun. All sub exposures were acquired from my backyard on Oct, 1-4 2013. - 25 x 30m Ha (5nm) - 25 x 30m OIII (3nm) - 25 x 30m SII (3nm) Total exposure time: 37.5 hours Equipment: Main Camera: QSI 583 WSG Guide Camera: SXV Lodestar (on OAG) Mount: Astro-Physics Mach 1 Scope: Celestron Edge HD 8" with 0.7x reducer (FL: ~1480mm) Image Aquisition software MaximDL Registed, Calibrated and Stacked in MaximDL Post Processed with PixInsight 1.8 and Photoshop CS6
A weather front has arrived form the pacific Northwest, which means no more imaging for at least three night. So I got tired of waiting and just used the data I had: Exposures so far: - 25 x 30m subs in Ha (5nm) - 20 x 30m subs in OIII (3nm) - 10 x 30m subs in SII (3nm) total exposure time: 27.5 hours. In this rendition, I have mapped SII To Red, Ha to Green and OIII to Blue. I have then extensively tweaked the hue and a/b ratios in L-ab mode to get a yellow/red over blue color scheme.
