Description

The Worm Moon of 2022, imaged on 20220319 0001-0103 GMT. Definitely check out the full resolution version! This is a mosaic of 46 individual images, each stacked from the best 25% of 3000 frames. The total raw data captured was 276GB, though I captured more than that to ensure there were no gaps. The pixel scale is 0.22", i.e. each pixel of the image represents 410m x 410m on the moon.

This was my first big mosaic and it was a grind to process, even just stacking and preparing the individual panels took over a day, and while Hugin gives great results its control point generator can be a bit quirky. It certainly didn't like being given all 46 panels to stitch at once! I found it was best to add a "stripe" of panels and generate control points for that before adding the next stripe of panels and re-generating the control points, and so on. It was also fiddly working out the exact horizontal field of view for each frame, sadly Hugin doesn't let you just specify a pixel scale for all images.

Overall I'm pretty pleased with the detail I wrung out of a 6" telescope.
