May 8, 2022: 7-pane, 72 Mpixel Lunar Mosaic under good seeing conditions


Recommended Posts

I got the C8 out last night, and before hunting the supernova in NGC 4647 I had a bash at some lunar imaging with the ASI183MC camera. I took 7 1000-frame SER files and stacked them with AS!3. Seeing was so stable I could stack 50% of the data. I feel I pretty much nailed focus as well. I stitched the panes in MS-ICE, sharpened the result and applied curves in ImPPG, and combined the unsharpened colour version with the sharpened grey-scale version in GIMP, by doing an LAB decomposition of the former, replacing the L channel with the sharpened grey-scale image, and recombining the channels.

For some reason SGL doesn't allow me to upload the whole image, so I have posted a link to Flickr. By all means check out the full resolution version.

I may play around with saturation a bit for a mineral-moon version.

Very nice! I was looking at the Moon last night (only visually). The seeing was poor but at lower powers it was a nice  view with dramatic shadows on the terminator.
