Much thanks to Lloyd for providing excellent Lum data from Deep Sky West.
It's impressive the difference a really good site makes. I dare say this image is held back by the CCA-250 / Aspen 16 data.
Excited to collaborate more with Lloyd, Hytham, and others at DSW in the near future.
The Lum data is a combination of DSW 60/120/600 second data and 300/900 second data from Prairie Sky Observatory (PSO) in Bloomington, IL.
All remaining data was captured at PSO.
