Description

Sh2-170 aka "Small Rosette" nebula: a small and faint target

Same data from early November 2022, redone from start, to incorporate BlurXT for better stars deconvolution and nebula sharpness.

35 x 240sec light subs
30 Darks, 30 Auto Flats, and 30 Dark Flats

Stacked, integrated and post processed in Pixinsight as RGB, and touched up in Paintshop Pro for clarity and vibrancy. Originally, the Stars weren't perfect as the dew heater ring kept giving me problems, but the test was mainly to assess the nebulosity capturing limit of the 8" SCT (Nexstar Evo) on the AVX mount. Full resolution and coordinates on Astrobin:
