55+ hours I think that may be a record for one frame without combining several scopes or archived data on IIS, anyone gone longer? Not sure it was really necessary but if you can, heck, why not?

Personally I'm too not fussed on the diffraction spikes, they look fake, I would suggest making them much thinner and more subtle

You must be wrapped with the new Observatory when you can do this sort of project

Thanks Mike!
The diffraction spikes were kind of an after thought, but I quite like them.
I will see if I can make them look more natural.

also one of the major stars in the Rosette cluster is yellow

Trevor,
Thanks for the feedback!
Oh and d) read entire post before making comments!

The attachment is in relation to the text part of the post

Thanks Martin,
I do have the full NB set, and yes that will be on my next thing to do list.

Cam,

55 hours sounds long, but given the subs were 30 mins each, thats only 20 or so subs per channel.
I also used 5 minute subs to bring out the star colours, but even at 5 minutes the bright ones are saturated.
