It's taken a week to put together, and about 100,000 frames of video, but finally here's my Clavius image from data taken last Sunday.

The image posted here is half-size. If you're feeling brave you can get the full size image here:

Capture: 9 panels, each 11000 frames, 40fps @ fl=14,000mm
red filter (Astronomik).

Oh snap! :eyepop:

That image is fantastic! That looks like the kind of image you'd find on the internet from the Lunar Orbiter probes or Clementine! Fantastic shot! Definitely submit it to LPOD!

B R I L L I A N T !

Just beautiful, Anthony. Well worth the effort I'd say.

How long did you spend recording?

Recorded from 9:32 until 10:13, so just over 40 minutes (with small gaps to reposition) at about 40fps. :-)

cheers, Bird

Thought you Lunar guys might be interested in Retinex Image Processing.

Some samples here
http://dragon.larc.nasa.gov/retinex/Lunar_Orbiter/

I put a before and after below from a Lunar Orbiter. They look almost as good as Bird's images.

And you can get the software here. There is a free trial available.

Bert, I had a go at processing the before image you posted here, I was curious how my system stacked up against the commercial one...

Here's what I did:

- Load before.jpg image into Astra Image, rescale 2x
- Convert to greyscale
- deconvolve Maximum entropy, 10 turns, radius 1
- save

Load image into The Gimp:
- selective gaussian blur
- levels adjust (Gamma increase to 1.9)
- unsharp mask, radius 1, power 0.5
- scale down to 50% (ie back to original size)

And this is my result. Comparing it to the "after" image from Retinex, I think it's a close thing, maybe I like mine better :-)

If I'd started with a lossless image instead of the before.jpg then could likely improve it a bit more.

cheers, Bird
