Description

Acquired multiple frames a couple of months back for this region, ~160 x 300s images  @ -10c & 100g, 1x1 bin, ~85% were usable for Ha, ~65% for Sii, & ~85% for Oiii.

Blink / Subframe Select, Calibrated (100 Dark, 60 Flat, 100 Bias), Star Aligned all images with PixInsight. Used the Normalized Scale Gradient for integration - this knocked many Sii sub-frames out. 

For Ha, Sii, & Oiii channels: Dynamic Cropped, TGV, MMT (& duplicated the Ha here for the Lum), EZ Soft Stretch,  and Channel Combined Sii to R, Ha to G, & Oiii to B.

The duplicated Ha -> Lum was Dynamic Cropped, EZ Noise'd, Mask Stretched, STF Stretched, HDR, DSE, LHT, MMT, EZStar Reduction, and LRGB Combined with the Channel combined SHO image.

The image was Curves modified w/ masks, Resampled, and Annotated. 

Please Enjoy!
