Trevor,

Cheers.

Not sure what's the cause of the halo other than perhaps severe stretching? I could have masked it out, but, meh. I'm not too fussed with this effort. Pity Orion doesn't present itself as a winter object!

whats the cause of the large halo though on the brightest star

high temp does plays havoc on uncooled DSLR's I'm just hanging in there until I can afford a COOLED CCD although a dark site helps
Doug,

Thanks, mate.

Yeah, the banding is visible in shadow regions. I can't see any through midtones or highlights.

I do have my eyes on an ST8300M, but, will have to wait a while. Got some other products to buy and holidays to go on! Mind emailing me at octane2 AT optusnet DOT com DOT au -- would like to have a chat re: Snake Valley.

I see the horizontal banding near the bottom of the image and can offer no sugestion what would have caused this. Had you been using USB to transfer the image I might have thought it could have been a USB delay problem.
Noise is a big problem with DSLR's and hot weather. Need to get yourself something cooled.

Nice image.
Thanks for looking and commenting, guys.
