Clavius and Copernicus reprocessed

Hi all.

Here's a couple of shots that were captured on the 23rd January 2006, that at the time were ok, the seeing was "ok". I posted them back then, but I thought I'd give them a reprocess using my new lunar processing routine..

I think they've come out much better.

The original is on the left of each "pair", and the reprocessed version is on the right of each pair.

I'm quite happy with the new processing routine - it seems to undo some of the nastiness caused by seeing.

Comments welcome.

Mike, the difference side by side is substantial - a big improvement in detail on what I already thought were great shots (I'm yet to produce lunar shots of calibre of your originals here). Amazing!

SO what's the key element of the new routine?

Thanks Robert.

My old routine was:
- Mild wavelets in registax
- New Layer->Highpass (hard light) filter in photoshop (opacity 30%)
- Flatten
- Unsharp Mask
- Contrast Adjust

My new routine is:
- Mild wavelets in registax
- Open in AstraImage
- Split colour planes
- Delete red and blue channels
- LR deconvolution on the green channel
- Mild unsharp mask (if necessary)
- Contrast adjust (if necessary)

Good one Mike, so the Green Channel is the way to go - must give that a try myself. Assume you'd have to process in Registax in colour? I often process as B&W for the moon.

cheers,

Well I've probably missed the benefit of the green channel in this case, because I captured in B&W and processed through registax in B&W, so in this case it probably wouldn't have mattered what channel I used.

Next time I'll be capturing in colour and splitting the avi and process only the green channel through registax.

Thanks guys.

They're partly dark because of the low sun angle, but the LR decovolution darkened them even more. I'll see if I can brighten them for teh next lot.
