      Description

      After finishing up my Orion project, I did not have much of a target selection in terms of narrowband or RGB for my widefield setup. I was talking with @James and he said why don't you point at polaris region, never goes down and you can shoot a 1000 hours if you want . That's what I did here for the past few months, but not a 1000 hours though!

      I kept piling on Lum on clear nights and after stacking for a couple days, the lum data looked awesome after DBE. On my previous dusty targets, I think I stopped on L after 20 hours or so, but I could see fainter structures here with no decon or enhancement done. 

      Hope you like this result. Clear skies!
