M1 taken with Planewave CDK 500/3550mm Teleskop at Peterberg Observatory
www.sternwarte-peterberg.de.
Canon EOS450d, modified, 280 x 30 sec, 1600 ASA. 70 Darkframes.
Fully processed in PI, esp.
- Histogram Transformation
- Deconvolution (10 iterations) in order to compensate slight focus shifting during exposures.
-
HDR Median Transform with 7 linear (factor 1) Layers and adaptive noise reduction on the first 5 layers.
==>
is a really great tool, I had much more noise using ATrousHDRWavelet only.
- ACDNR with noise reduction (lightnes mask on luminance , removed 3 layers) + chrominance without lightness mask
- Saturation increased on the "red" and "green" colours.
