This is a two shot mosaic of
Mare Nectaris taken last Tuesday night. The large crater at the bottom of the mare is Fracastorius. I found a great on-line
Moon map that helps me find these details.
The two images were stacked in Registax, 400 frames each, then combined in Photoshop. All other processing was done in PixInsight. Both images were shot through a C-8 at f10. Seeing was not good as the Moon was low in the sky, maybe 2-3/5. I could see the image swirling in the AVI. I used 4 align points in Registax for each image.
In processing this image, I learned, from a practical rather than mathematical perspective, the differences in resampling algorithms. I upsample the image by 2x at the start of processing. Bilinear increases noise, Bi-cubic is better, cubic has less noise but softens part of the image.
Thanks for looking.
