Dennis,
You got a great shot at this object. Congrats!

When I did this object, I got the amorphous blob.

Thanks guys for the comments..

Ivan, I think there are just not a lot of these Artemis cameras out there. They come in kit form and I think that scares a lot of people off. Atik now has a fully assembled version of this camera.

M42 with New Eyes

Posted By Jim Thommes
Dan,
I've always admired your images on your website. I guess I really don't see "warts" that well.

Anyway, your posted M42 is a great image - it does appear a bit dark on my monitor. I can turn my gamma a up pretty high and it still looks good. If I do the same for my images, the warts really pop out.

A rediculously simple question... *grin*

Posted By Jim Thommes
Paul,
I agree with Dan and Mike. If I have a limited time or a time budget, I will generally favor longer/fewer than shorter/more. I think this will generally apply to all but lunar and planet imaging.

However, the 8-bit Atik will offer some challenges balancing the sky noise, read noise and pixel saturation. It may mean that there is a narrower "optimum" exposure time range than with that of a 16-bit camera.

M81 through a gap in the clouds

Tom,
Really nice image... But I really like the Wide field shot with M81 and M82 - Cool.

Now for something completely different.....

Posted By Jim Thommes
HA! Got me curious... Glad I looked. Congrats Vince, really good job in the core area and the full nebulosity as well. Great depth and color on the stars and a nice natural look.

I have one of these in the oven for this year too. I will be using this image as a benchmark.
