imaged NGC 2403 (Halifax)

I really didn't want to go for galaxies with the Moon out. Alas, BGO imaged NGC 2403 (aka Caldwell 7) for me. A big spiral galaxy in The Giraffe. One of the RASC Finest NGCs.

RASC Finest galaxy NGC 2403 luminance

Luminance only, 60 seconds subexposures, 10 stacked shots. FITS Liberator, Paint.NET. North is up; east is left.

Seems soft or dim. Gradient coming from the right (west) edge. Maybe I'll try again later...

An interesting feature of this canted galaxy, even though over 10 million light-years away, is the very large nebula visible. That's NGC 2404. To us, it appears just east of the core.

Quickly assembled the data for a colour image.

While updating ST3P, I found this NGC in my "edge-on galaxies" list. Ah, no.

Forgot that I quickly imaged this with the SLOOH system back in Feb 2011.

Collected better data on 3 Feb.
