Description

I have spent several months learning and acquiring my first rig. This was the first successful color integration via my third shoot (in my backyard). Process listed is for final image after 3-4 attempts at new method.

Process details:

- Blink: Removed one heavy streak sub, two off target subs

- WeightedBatchPreprocessing Script: Calibrate only

- Cosmetic Correction: Auto Detect ~1000 hot, ~1000 cold pixels from sample frame, apply to all subs

- SubframeSelector set weighting to:

(15*(1-(FWHM-FWHMMin)/(FWHMMax-FWHMMin)) + 15*(1-(Eccentricity-EccentricityMin)/(EccentricityMax-EccentricityMin)) + 20*(SNRWeight-SNRWeightMin)/(SNRWeightMax-SNRWeightMin))+50

- StarAlign: Use L ref for all subs

- LocalNormalization

- ImageIntegration: Generate drizzle

- DrizzleIntegration

- DynamicCrop: Set crop on L, drag to other frames then apply to L

---- Update - New process picks up here for final image versus original process for version C below ----

- ABE (for linear gradation from left to right): Interpolation and output = 2, Correction = Subtraction

- EZ Processing Suite->EZDecon (L only)

- EZ Processing Suite->EZDenoise (all channels)

- EZ Processing Suite->EZSoftStretch (all channels)

- LRGB Combination: Set Chromanance Noise Reduction, join all 4 channels

- Curves: rough RGB/K, S adjustments

- HistogramTransformation to kill background on L mask, Convolution: Apply 2-3 rounds to blur mask

- ColorSaturation : use with mask and toggle mask as needed for fore and background adjustments

- HDRMultiscaleTransformation

- ACDNR

- Curves to darken background

- ColorSaturation touch up galaxy

- Use Gimp for minor touchup of few stars missed in EZDecon

- Topaz Dezoise entire image

-------- Update -------
New process from Steve at his "Entering Into Space" YouTube channel - "Processing M81 with New Techniques!!" was used for the latest final version and picks up right after sub frames are dithered and cropped.
