Default Plato Craterlets

Reading Sky & Telescope on the way back from a conference, the Exploring the Moon column was about the discovery of small craters or craterlets in the crater Plato. An interesting article.

On arriving home, I decided to try and see these elusive craterlets and opened up the observatory. I found them and was able to image them. Seeing was not good, but I got one OK AVI at f30 on the C-11.

Processed in Registax, PixInsight, and Photoshop.

I wrote more about this on my web site blog.

P.S., Sigma reject on the combine helped reduce the effect of a dead pixel on my web cam.

hi Andy,

very nice plato-image!
did You use PixInsight for sharpening and/or smoothening...?
I love to use Pix IS for smoothening my deepsky images`background a lot.
but I have little experience in sharpening details.

I used the HDRWaveletTransform to sharpen the image. I did two iterations on 5 layers with a luminance mask. I then used a single iteration of GREYCstoration noise reduction to smooth out the image.

PixInsight is a very cool application. IMHO, well worth the effort of going up its high learning curve.

Thanks to everyone for the kind comments!

I did some more processing on the comparison (30 vs. 10 fps) images of Plato taken a few days after the original. The 10fps was the nicer image, its higher noise was easily handled by PixInsight.

The bright portion is still overstaturated, but it is a nicer shot.

The result is attached.

Clear skies,

--Andy
