Kinda spooky looking.
Awesome image.

A wonderful image Tom, I love the colours and details.

i'd be interested in how you determined the colour balance for the final image. i've tried G2V star calibration previously but on a test shot of this region last month i ended up with colours that seemed way off to me? what's your process?

I generally use G2V calibration and then adjust from there. I also use gradient removal plugins on most of my images, but this likely alters the G2V calibration. You may want to try Bob Franke's eXcalibrator to see if it helps your colour balance. I have not used it but I know that many of the "big" astroimagers use it. http://bf-astro.com/eXcalibrator/excalibrator.htm

For object ID and framing I use TheSky6, Desktop Universe, Aladin, Wikisky.

Once again thank you everyone. This really is the friendliest, most neighborly astroforum on web.

Thanks Tom.. I use TheSky6 for scope control and especially mosaic planning but will need to learn to use its databases at a deeper level. Will have a look at eXcalibrator and the other data sources as well.

Keep sending us your very inspiring work!
