Hi all,

Two days ago i went out, the sky was clear, and i took the chance to shoot the moon with my Canon A710 IS.

I used a standard tripod, and used the Fast Intervalometer script to make as much shots as possible in the shortest
amount of time.

I set the cam to manual mode, continuous shooting, ISO 80, shutter speed 1/125s, maximum zoom, manual focus set to infinity, and set the script to run for about 3 minutes.

Because on my memory card it takes about 2 seconds to write a single RAW file, that time was enough to take 95 pictures.

Then i converted the RAWs to DNG using the DNG4PS-2 (DNG4PS-2), and then using UFRaw-Batch (UFRaw - Home) i converted them to PNG.

Then i used RegiStax v4 (RegiStax V4) to stack the images together to get an image without noise and with all the details combined from all the images, so more details could be extracted from that picture using wavelets. (you can read about this in the RegiStax manual)

The results are simply astonishing comparing it to the original frame taken with the camera.

I have converted the final image to greyscale to remove the cromatic aberation (the colour is not needed anyway because the moon itself does not have color), and resized it to 200% so you don't have to put your nose in the screen to look at individual craters  :)

I would like to see your comments on this, suggestions, questions, and also your similar images made using CHDK.

CHDK is an excellent piece of software and without it this picture wold not have been possible (to be this detailed at least).
Keep up the good work on CHDK, and if i have more time, i will join the team in making new features and improvements because i am a programmer myself (i work full time as a C++ programmer).

Regards,
Dime

This is a 'lucky imaging' stack (Registax4 multipont registration with 25 points) of 30 jpegs (alas, I forgot to set the superfine quality) taken by my S3 at the maximal digital zoom. With the better seeing and RAW photos I am sure the result would be better.
