Description

This is my second ever 9-panel mosaic. This time of the Bubble Nebula region in the constellation of Cassiopeia. Images captured over nine nights in a two week stretch of hot weather and in between smoke filled skies from wildfires. All frames were Astrodon HaOiiiL and Astronomik Sii filters.

All 1,161 frames totaled 35.37 GB of raw data to process. In all, 39.42 hours integration time.

135 x 60s Lum

342 x 144s Sii

324 x 161s Ha

360 x 90s Oiii

This was a difficult project to try and balance the light and gradients between panels. Each panel was processed using current mosaic construction techniques including dnaLinearFit process but still had some light balancing issues evident in the overall mosaic's bottom three panels. I'm going to make another pass at this one to balance the panels some more for a revision. Stay tuned
