This is my first attempt at a mosaic and I'm pretty happy how it turned out. This is an amazing part of the sky, there's so much going on in the surrounding areas it could easily be extended by several more panels in any direction.

As it is, this is three panels of about 8-10x900s Ha exposures each. I didn't manage to get them all to line up exactly so this is only about 80% of the total captured area as I had to crop the images a bit more than I would have liked. I'll also get some OIII and SII data when the opportunity arises.

I used this excellent tutorial from David Ault to put the mosaic together in PixInsight.
