Across 5 sessions during an unusually long stretch of good weather, the new cooled system (UHC filter plus first light of the ultra-narrowband H-alpha filter) produced my deepest and highest-quality image of Messier 101 to date.
On the edge of the final adjustments to my camera, this image was created.
