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.

Thank you,  Alan. There are a few images of this object posted on Astrobin recently. But imo, not many really do this gem justice.

Great result, looks like a mini M33.

Thanks. It is actually often compared to that galaxy.

I see you took it with an M/N 190, I have one sitting in the corner of my observatory which hasn't seen light for about 3 years. Maybe it's time to mount it up the CEM 60 I have should carry it easily enough.

Go for it. It's a great scope.
