NGC 2403

[Star101]

From WiKi

NGC 2403 (also known as Caldwell 7) is an intermediate spiral galaxy in the constellation Camelopardalis. It is an outlying member of the M81 Group and is approximately 8 million light-years distant. It bears a similarity to M33, being about 50,000 light years in diameter and containing numerous star-forming H II regions. The northern spiral arm connects it to the star forming region NGC 2404. NGC 2403 can be observed using 10×50 binoculars. NGC 2404 is 2000 light-years in diameter, making it one of the largest known H II regions, even larger than Tarantula Nebula in Large Magellanic Cloud. This H II region represents striking similarity with NGC 604 in M33, both in size and location in galaxy.

Taken this morning, 21 Sept19,  I think it requires Ha adding when I compare with other images online. I also found it difficult to process considering how much data I had. A very dark image.

That's another I haven't seen before, nice image you have taken but I personally feel it needs a bit more contrast Dave.

I agree. I will reprocess and se if I can alter that.

Thanks Alan.

Reprocessed....Maybe over processed, but reprocessed to give it more contrast

Only after I took a good step back and looked properly at this galaxy that I noticed how BIG it really is. I should have used a focal reducer to get the whole galaxy in FOV. Adding some Ha may have helped too! And here I was trying to remove the faint spiral arms thinking it was cloud  

The larger circle is NGC 2403.
