Vallis Alpes

Hello everybody

This image taken Sept 1, seeing arround 4 - 5 so I was surprised to see the small rille.show up in some of the avi frames. The stacked image confirmed I got it. A first for me.

Sequence taken with handheld and unguided afocal sony handicam / GSO 10 inch / 10 mm Plossl .

135/200 hand picked frames stacked in Registax.
Exported aligned avi from Registax for further alignment using ImageJ and Stackreg plugin (stackreg can align x,y and rotation ) to reduce field rotation effects, note the image border hasn't been cropped out - it worked well.
Final alignment, stack and wavelets in Registax
Deconvolution using ImageAnalyser (not sure of the algorithm it uses but seems to work)
A Trous noise reduction in PixInsightLE and final tweaks in Gimp.

I have tried MAP processing but I don't think I gain anything perhaps due to residual field rotation or noisy data drowning out the result. I will keep trying anyway.

Thanks for looking

Mike
