Title: NGC 7331
Post by: andyschlei on 2011 October 10 21:00:57

I am reasonably happy with the results here, aside from the field curvature.

This is NGC 7331 in Pegasus.  1 hour, 50 minutes LRGB (50:20:20:20 | 10:6:6:6) with the color binned 2x2.  ST-10 on a C-11 @ f6.3.  Captured with Maxim DL and CCDCommander, reduction and processing in PixInsight with minor touch-up at the end with Photoshop.   The  video tutorial (http://pixinsight.com/videos/NGC1808LRGB-vperis/en.html) on the PixInsight web site is excellent.

Thanks for looking.  Click on the image to get to a larger version.

Clear skies,

Nice Work!!

I own a C11 too, I never achieved a good collimation like yours!
What's your trick?

Regards

Lex

Despite a slight blue preference, I like this picture very much, the composition is very well balanced.
The main object is NOT in the middle and ... thank you for that.
Do we see the golden ratio?

Lex, Thanks! I collimated using CCD Inspector (http://ccdware.com/products/ccdinspector/).  It was very helpful and not too hard.

Thank you too, Hans.  This version isn't as blue as the first one.   :D  The subject is also a nice opportunity to use the rule of thirds framing guideline.

Andy,

Thanks for the info, i also have this soft but i found out that i came to a better result faster "manually"  ???

I think i simply regime it a try with CCD Inspector; and read the instructions perhaps  ;D

Thanks

Cheers
