Full resolution image here https://www.astrobin.com/full/400167/0/?nc=user. Taken 09th April 2019, around 21:00 BST.
Equipment: Celestron AVX mount, Skywatcher 127 MAK, QHY5LII-M, TS 0.5x reducer.
Capture: each panel was captured in SER format, 1280x960, MONO16, 2ms exposure, gain=6, offset=10, 1 minute (~800 frames). Sharpcap 3.2 used for capture, with histogram set to 60% saturation. Capture was at 15fps.
Processing: each panel was stacked in Autostakkert 3, best 20% with 'Sharpened' selected. The 4 panels were stitched using Microsoft Image Composite Editor (ICE). Stitched image was loaded into Nebulosity, applied Curves > Contrast and Sharpen > Laplacian sharpen filter.
Offset was set to the minimum value possible and exposure adjusted to give ~60% saturation of the histogram.

Re: Lunar 4 panel mosaic,
These are the steps taken in Microsoft Image Composite Editor. Stack the SER files first, then stitch, then enhance the final image.
Step 1 > Import
Step 2 > Stitch
Step 3 > Crop
Step 4 > Export

Very nice Dave!

Cheers Wickett.
A good return on 4 minutes of capture with modest equipment. Stitching with Microsoft ICE is effortless.
