Description

9 panel mosaic in hydrogen alpha, each panel is made up of 45 x 2 minute exposures, so total mosaic is around 13 1/2 hours of exposure. This was my first mosaic larger then 2 panels. I used 10% overlap which created many challenges and caused issues getting good alignment. Next time I will use 15% overlap.

I also took SII and OIII but there unfortunately I did not take flats for these and they suffer from issues in the field so I was unable to use them. I still think looking at this region in Ha is still very interesting though. I may add RGB in the future and go HaRGB vs SHO I think it will look better that way.
