Here's my first image of the year. We finally got some decent weather starting at Easter so I spent a whole week collecting narrowband data on a few targets. The acquisition and processing skills were a bit rusty
Scope: Ceravolo C300 @ f/9 = 2760mm FL, Atlas focuser
Mount: AP900
Camera: U16M
Filters: Astrodon 3nm Ha, OIII, SII
Guiding: Lodestar / MMOAG
Image scale: 0.67 arcsec/pixel
Exposures: 14x1200s Ha, 16x1200s OIII, 23x1200s SII
(Over?) processed in PI. Constructive criticism appreciated as always...
