Description

Narrowband image of emission nebula in Auriga with bright SII signal. Imaged over 8 nights in January 21 although 44% of subframes were rejected due to poor observing conditions and scope problems -- It's now undergoing maintenance.

Ha 17x480s

Ha 35x360

OIII 20x480s

OIII 34x360

SII 12x480

SII 34x360

Processed in Pixinsight. Starting with noise reduction and deconvolution and then created starless tone maps for Ha, SII, OIII and enhanced luminance using Starnet. Aggressive noise reduction on the RGB and enhancedL tone maps and reduction of star halos. Used Pixelmath to combine starless RGB, enhancedL, and star image created by Starnet. Post processing to reduce noise and sharpen.
