I went really long with this one using
the MTO 1000mm f/10 mirror lens I have on semi permanent loan. To get it to mount to my camera and maintain infiinty focus I have to use a teleconverter and the only one of those I own is a 2x so here's what I got at 2000mm and f/20. On a crop sensor I can only get about 2/3 of the moon in the frame so I had to stitch the images and figured why not shoot a pile and stack them and try doing a super resolution shot of the moon.
So here is my stitched stacked 2000mm shot of the moon from last saturday Feb 8:
Camera: K-3
Lens: MTO 1000mm f/10 + soligor 2x telephoto converter
1/40s
f/20
ISO 100
Individual frames were developed in RawTherapee and upscaled 2x using nearest neighbor
Frames were aligned using Hugin
Stacking of the frames was done using Hugin from the command line using the default settings for sigma clipping average
The stacked image was 12000x12000 and final edits were done in RawTherapee using its wavelet editing functions.
