#103 - My 3rd and painful M42 :-)

Recommended Posts

Hi all,

before going any further...Merry Christmas and a Happy New Year.

This is my 3rd M42 (second with the Luis Campos 450d MonoMod Canons. I've blendes H-Alpha with RGB, after going through a painful learning process with PI's HDR Composition, since both RGB and Ha images had to have HDR done with their different exposures to cover M42's huge Dynamic Range.

So the method in short was:

Ha + Ha

RGB + RGB

HaHDR + RGBHDR (PI's NBRGB script)
