NGC 2403

David says: “This galaxy is rich in colour, hav­ing many HII star-form­ing re­gions, which ap­pear pink in the im­age. Cloud meant I had to take fewer ex­po­sures than planned; the outer spi­ral arms are faint and stretch­ing the im­age to get them to show meant there was quite a bit of back­ground noise to deal with.”

Equip­ment: Starlight Xpress SXV-H9 mono CCD cam­era, SkyWatcher Ex­plorer 130P New­to­nian re­flec­tor, Sky-Watcher HEQ5 Pro SynS­can mount.
