moonshot redone...

I agree. Very nice detail, and the contrast stertch seems about perfect. Really an amazing amount of detail here. Nicely done.

Kodak sensor engineering grade

Posted By Ron Wodaski
There is a huge spread in the quality of engineering grade chips. Some of them are very close to regular grade; some of them are just horridble. Unless you can see the defects in the chip in an image, you won't know what you are getting into. If you can check it out, then you know and you can make a good decision.

Softwere for Realigning RGB?

Posted By Ron Wodaski
Photoshop can do this without even having to break the color challens out separately, but it's very expensive. There are two clones of Photoshop out there, PaintShop Pro and Picture Window Pro. Both presumably offer similar feature.

And I would think that Mike Unsold's ImagesPlus program, which is designed around astro image processing, would be one an excellent choice for this problem because it would give you so many astro-specific options.

Beautiful image, Jeff. The color in the Trifid is really sweet. And all those stars!

First Jupiter image TEC200

Gorgeous images, but some serious blue fringing! Have you tried realaigning? Or was the rotation of the planet just too fast to keep up with?

ngc 6894 planetary nebula in Cygnus

It may be small and faint, but you've captured it nicely. I can make out details on the ring very easily. Nice work.

Beginner's Equipment Choice

Posted By Ron Wodaski
The ST-237 is the better imager between it and the STV - the STV has lower dynamic range and higher read noise. The STV is the better guider from a convenience standpoint (no laptop), but the ST-237 is an excellent guider. My own choice was to use the ST-237 as my guider, and to dedicate a cheap P150 laptop to it.

The ST-5C is used by a number of planetary imagers, but it has large pixels and is only well-suited to very long focal lengths. it has a larger dynamic range than the other two cameras, and that is what makes it good for this purpose.
