Simeis 147 (Sh2-240) supernova remnant - 3x2 mosaic
After 4 month I finally decided to en this project.
Initially I thought I would take 10 hours per panel, so total of 60 hours, but in the end I got 'only' 45 hours.
Weather in Spain (where we have remote observatory) has been unusually poor this winter, hence the long project. Also this was a joint project with Aarni who also used his imaging nights on this.
Sky-Watcher Esprit 100ED, 10 Micron GM 1000 HPS, Atik 460EX, 1400min Ha, 1400min OIII (so HOO palette).
Some words on processing.
Most likely I did processing the 'wrong way' to save processing steps, but luckily I had so good data that I got reasonable result.
So I make 2 processing runs. One for each channel.
I just loaded all 95 files for all 3x2 mosaic pieces together with calibration files and let APP do its magic.
It took over 3 hours to process for each channel, but I think it was lighter task (for me) than process each mosaic panel individually.
Hope you like the result.
Myself I'm glad I have now done this and go forward to normal 'easy' project.
This is very nice! I admire your great effort in doing this image. Thank you for sharing.
Superb result @einari 🙂
