Thanks everybody for your comments - I appreciate them.

Hi Jim,

I guess you can scratch that question from my response to your M63 image. Who makes this camera? Nice, looks like you have a potential winner there with the SXV-H9 chip camera!

Eric
Fellas by the names of Steve Chambers, Jon Grove, and Arthur Edwards designed and build these cameras. They have a website with a lot more info on it:

M13 (Third with Artemis285)

Posted By Jim Thommes
Thank you all for the comments.

Denise, the reference given is indeed the website of the designers / suppliers (kit form).

Stuart, the camera I was using is the monochrome version. So I do 4 exposures a luminance and R,G,B each with R,G,B dichroic filters). I combine them in postprocessing to form a color image.

M64

Posted By Jim Thommes
Eric,
Nice luminance - looks like it has promise and warrants some color data.

Funny how things can turn out well that you don't have much expectation for during the exposures. And unfortunately it works the other way too sometimes - you can get excited about exposure data when you are taking it only to have your expectations somewhat disappointed after processing.

Anyway, this one looks like one of the more pleasant results - good image!

Brian,
This is an impressive image. I have to say I don't usually see M101 in this wide of a field - its quite attractive, congrats.

Galaxy NGC 3628

Posted By Jim Thommes
Well, thank you all for the comments on NGC 3628.

I do enjoy using the webcam - bear in mind, the SC3 mod with RAW firmware makes this a highly modified webcam - like an Atik-2HS Camera.

But after using the Artemis285 (other recent posts), I really do enjoy a 16 bit 1.4 Mpix camera a little better than the webcam.

Thanks again for the comments.

Steve,
This is a great image. Very good detail on the galaxy disc. Great tracking too. Thanks for sharing.

Globular Cluster M10

Posted By Jim Thommes
Greg, Ivan,
Thanks for the comments - much appreciated.

Ivan,
I think I will be upgrading to something at some point in time - probably sooner than later. Yes, the ToUcam may see little use at that point. But selling it - ouch! perhaps I am too sentimental and have grown to attached to it. It seems too much like an old friend.

Very nice, Jim! It looks a little too magenta on my monitor, however. You might try tweaking the color a little bit.

What is this Artemis285 camera--I am not familiar with it.

Excellent focus and guiding, BTW.

Jeff,
Thanks for the comments and input on the color balance. I had actually rebalanced -8 on red and 8 on blue in the midtones from the original which I though was a little too yellow. I might try to play with it a little more.

The Artemis camera is a kit camera. You can get more info here:
