Last night was a mixture of high cloud and a reasonable wind, but as everything was set up, and gave the tarantula a go.
Ended up with 60 min of Lum in 10 min exposures and 20 mins in RGB in 10 min subs. Processed, aligned and stacked in CCD stack and edit, slight crop and general processing in CS 3.
Comments / criticisms / tips appreciated.

Darren,
It's good to see some of the red Ha? appearing in this image. A lot of tarantula shots seem to only show the blue.

Not bad Darren from the scale I'd say you used the 120 (attached is one I did with the ED80 a while ago using a 350d, 15X3 min), colour looks good, some star elongation appearing in corners much like in my first attempt.

Thanks Peter and Yes Trevor, through the 120.
There are so many variations with mono imaging, I'm still doing lots of different processes and figuring out what I like.
Also looking at lots of other images and trying to end up with something similar. It's just nice to out and getting data!

This has come up very nicely Darren. The only thing I would do to make it pop a bit is to lift the red channel a little and maybe the blue using a selective hue and saturation increase.
The big mass of stars surrounding the nebula are quite blue and the rich Ha base of the nebula appears a bit more red.
Looking good though. Looks like the camera is a winner in the 120.

Yeah Yeah I suppose it's all right :zzz2:
Hey Dazz, it needs to be copy/pasted to a new copy, printed out, framed, and made ready for display at Camp.
Then you can really show it off :lol:
Good work mate :thumbsup:
It is a nice image Darren, maybe a little over cooked, so to speak but a job well done indeed.

Thanks all, appears a little over cooked Leon, but I was shown a couple of new blending tips tonight, so hopefully the clouds will go away and I'll get some more data and have another go at processing tomorrow!

Looking good Darren, make some short exposures to get the core not burned out and blend that in :thumbsup:
The tarantula is pretty hard to process and easy to get the core burned out.
PS: the next best thing to get is a HA filter :)

Thanks very much Marc, and Yes Martin, the Ha filter is on the shopping list!
