Iris Nebula Under Less Than Ideal Conditions

[StuartJPP]

It was predicted to be clear, not that I taken them too seriously, but on the night I could barely see Megrez at magnitude 3.3 (Big Dipper) due to very thin cloud. But I still carried on regardless, otherwise at this rate every time I use my kit it would be like learning it all over again.

I was testing out a new head configuration which allows me to actually point my camera up to image this object as previously I couldn't get anywhere near zenith.

Canon 7D With Canon 500mm f/4 L IS @ f/4

AstroTrac TT320X Mount.

50x 60 second subs @ ISO 1600.

A fair bit noisy and not ideal. Will revisit this when conditions are a bit better.

Looks very nice all the same.

Do you know what all the verticle streaks are in the image?

Noise

Ah yes, summer pop concerts and trendy young people playing their transistor radios and phonographs very loudly in their back gardens!

Nice image Some of the vertical streaks I can see are my monitor - it's not the best quality but it works

Nah, I think I stretched the data just a bit too much and the noise crept in. I was really trying to get some of the dark stuff which is slightly visible though the vertical stripes

I like this a lot, It's one I attempted once and found my alignment was off so not even worth processing. Great stuff
