NGC55 - An (now HaRGB) Irregular Whale

Here's my take on NGC55 (The Whale) - an irregular galaxy in Sculptor, and one of the closest of our local group neighbours. At a measly 6.5Mly away, there's plenty of lovely detail to observe, with pockets of Ha, dusty tendrils and a plethora of new bright blue stars.

My shot from the Sydney suburbs is over 2 nights, over 2 new moons, to end with a total of 5hrs of data in somewhat below-average seeing conditions. Taken with the asi2600mc, I haven't added any additional narrowband data at this point, so the Ha regions are not as pronounced as some of the excellent deeper shots by others.

Still pretty happy with how things have come out, and maybe might invest in a Ha filter down the track to enhance things further. As always, happy for your constructive criticism too!

Thanks for taking a peek!
