NGC7331 and Stephan's Quintet

Recommended Posts

This image of the area around NGC7331 and Stephan's Quintet was taken earlier this month using my SW MN190 and QSI583 camera. The field is about one degree wide with north to the left.

Conditions were bad with poor transparency, and even with about 3 hours luminance and 3 hours RGB, the result was noisy and needed some brute force in processing.

Subs were just 200-300 sec. unbinned (1x1), about the limit for my milky suburban skies.

It's a work in progress: if we get some better conditions, I'd like to add some cleaner luminance data, and some H-alpha frames to bring out the star forming regions.

Good image, plenty of detail, nice to see all those galaxies in one shot, you did a good job of removing the noise!!

That is absolutely stunning, a really nice image, great detail, and lovely colours i count more than 31 fuzzys, my favourite is probably in the bottom left, lovely spiral

Thanks for the kind comments. It's an interesting field with so many small backgrund galaxies visible, but it really needs more exposure to bring out the faint stuff more smoothly.

Yes, this one seems to need a lot more data than most. I've had a few attempts but not managed anything really decent yet. I think it's a lot harder than it looks so hat's off to anyone who does get a decent result :)

Lovely. As has already been mentioned, it's so chock full of galaxies. Every time I thought I'd spotted them all I found another :)

Wonderful image, has kept me enthralled for ages trying to count the galaxies.

Thank you :grin:

Great image Adrian - good luck with the extra Ha tonight - in danger of going to sleep counting the background galaxies.... :grin:
