Fantastic image. The rgb technique seems to capture very smooth color information. Could you give us a very general description of the work flow for generating Lrgb planetary images and any particular challenges it presents?

Also, could you post a single frame of the raw greyscale image ?

Thanks

Mounts for a Celestar 8

The bolt pattern for the Celestar drive base and the older Grey cast forks are the same.

Canon D20 and DSLR Focus

Posted By Joe Baldwin

Please keep us posted on this issue. I was debating whether to buy DSLR focus since I didn't think the support for the 20D was complete.

Another Saturn from the Northeastern U.S.

Ed,
Great image. That is the best 8" Meade image I have ever seen. Nice job with the processing - bands look nice.

Solving the "ringing" problem with processing

Posted By Joe Baldwin

I notice this same effect if I try to crank up the detail using Registax wavelets. It is very easy to overdo it. Use just enough to clarify the edges and then save the image and apply a small radius unsharp mask in an image editing package to sharpen. Also try using the planet limb as your alignment feature and see if it helps . A far as gain goes, more is better-just don't saturate.
