Description

This is my first mosaic, a 2x2 primarily centered on the dust between the Cygnus Wall and Pelican nebula. It look me a few tries to get the settings right in AstroPixelProcessor; I've put what I used below.

Thanks for checking out the finished result!

-----------------------------

AstroPixelProcessor

-----------------------------

First stacked each 4 panels separately and for each filter, so 12 separate stacks. Settings left at default except LNC set to 2nd degree with 3 iterations.

Next, stitched the 4 panels together (one set per filter), bringing them in as light frames. Used the following settings:

[Registration]

- Scale Stop = 10 (increase if needed based on overlap)

- Dynamic Distortion Correction = CHECKED

- Same Camera and Optics = UNCHECKED

- Registration Mode = Mosaic

[Normalization]

- Mode = advanced

[Integration]

- LNC = 2nd deg 3 iterations.

- Enable MBB = CHECKED

- MBB slider = % of panel overlap, 18% in this case.

1. Deconvolution on Ha only.

2. TGV Denoise & MMT (Jon Rista method) used for noise reduction.

3. Masked Stretch, then Histogram slightly.

4. Star Reduction on Sulfur II using Adam Block technique with Starnett++.

5. PixelMath SHO combine:

---- Red: 70% SII, 23% Ha, 7% OIII

---- Green: 20% SII, 60% Ha, 20% OIII

---- Blue: 8% SII, 8% Ha, 84% OIII

6. Star Reduction on clone of Ha, used for Lum, then applied to RGB.

7. Color adjustments, SCNR, masks with curves, etc...

Photoshop

----------------

1. Saturation adjustment, final color tweaking.

2. Spot cleanup of over-saturated stars.

3. Smart Sharpening with edges mask.
