I started this project more than one year ago.
I threw in a lot of the data that I had available.

Last season I first tried to capture 3 panels from the belt to the M42 with the Esprit 80 and a Canon 6D. Goal was achieved and I got this:

This season I continued and I added ~20h with the Esprit and the 6D in multiple panels with "portrait" and "landscape" orientation. Meanwhile, when I didn't travel to dark sites, I captured from home the same area in Ha with the 72ED and the ASI1600. ~18h of various orientated panels.
After capturing at least 3-4h of DSLR data for each panel combination, I figured out I still had some time to try to shoot some luminance with the 72ED and the ASI1600, covering the same area I did for the hydrogen. So I managed 1h x 9 panels of luminance too which I combined with the luminance extracted from the RGB.

6h with the 130PDS and ASI1600 were used for the M42 area. Original processed image:

With all my efforts to keep things well organized, I find it very hard to describe in detail how all the panels were planned, combined and processed.
In total I spent over 100h exposing this area and not everything went in the final image.






Description: 9 panels of 1h of luminance with 72ED and ASI1600.


Description: "portrait" and "landscape" panels of Ha with 72ED and ASI1600. 17.5h
