This is by no means a masterpiece, but wanted to share an image I got of the ISS transiting the moon, taken from my back yard on 10/8/2019. This was shot through my 8" LX200, with focal reducer, and my Canon 600D. It was around 8 pm, so I wasn't able to get the mount aligned as the stars were not visible yet. I was manually guiding the scope through the viewfinder, with the camera taking continuous shots as the ISS approached the moon. I had to shoot JPG, since the buffer fills after 5-6 RAW shots, but the camera seems to handle JPG just fine continuously. Or at least for the 30 seconds or so I had it firing.
I took the 15 frames that showed the path of the ISS, aligned them in Nebulosity 4 with the automatic/non-stellar alignment process, then stacked them to show more detail on the moon. I then brought the aligned frames and the stack into GIMP and used layer masks to bring the individual shots of the ISS onto the stacked image. Full disclosure - I only captured two of the images of the ISS in the portion above and to the right of the moon. The frame was too narrow to capture more of the field. I artificially increased the canvas size and copied the four images of the ISS above and to the right of these. I think it makes a prettier picture, if not authentic. If this bothers you, please feel free to ignore the top of the image...
I haven't done much with stacking or compositing lunar images, so any suggestions for how I could do this better would be appreciated.
Thanks in advance!
