Sharpless Sh2-170

[Tom How]

Not far from my previous CTB1 target is Sh2-170 from the Sharpless catalogue. This is about 20 arc minutes across, so a bit of a squeeze on my setup.

Didn't clear last night until gone 11pm but I was about to get 12x1200s frames with the Astrodon 3nm Ha, Skywatcher 200 and the homemade telescope mount.

Not very good star shapes - but I had the mirror off yesterday for the annual clean, so anything could be out of alignment. I'll fiddle with that when we get one of those full moon clear nights!

I like this one Tom, always reminds me of a 'baby rosette' nebula.

That looks a difficult target Tom - on the growing list

Nice one, Tom!

That 3nm filter is starting to look irresistible.
