wimvb Posted February 19, 2022 Share Posted February 19, 2022 (edited) Ngc 2403 is a liner galaxy in the constellation Camelopardalis. The galaxy has a diameter of about 70 000 light years, making it somewhat smaller than the Milky Way. It is about 10 Million Lightyears distant. The galaxy is a member of the M81 group of galaxies. Capture data: Telescope/camera: Skywatcher 190MN + ZWO ASI294MM-Pro with Optolong LRGB filters and Baader 7 nm Ha filter RGB: 220 x 4 minutes exposures L: 270 x 3 minutes exposures Ha: 80 x 4 minutes exposures Captured 26 January - 11 February. Total integration time, approximately 2010 minutes (33,5 hours). Processed in PixInsight. I just (20 feb just after midnight) put this version on Astrobin. I added Ha to luminance to get better definition in the Hydrogen clouds, and dialed the blue back a little. To get this image where I wanted it, I had to experiment with LRGB combination, using the channel weights to increase colour.

There are a few images of this object posted on Astrobin recently. But imo, not many really do this gem justice. Link to comment Share on other sites More sharing options...

Maybe it's time to mount it up the CEM 60 I have should carry it easily enough. Alan Link to comment Share on other sites More sharing options...
