First Crab Nebula Image

[Hawklord]

Hi All,

Just starting on the learning curve of cooled ccd imaging. Here is my RGB effort from last night. Have never imaged the crab before. 3minute subs for all, 72minutes in total. Pretty bad light pollution where I am. Vixen VC200L (with F6.4reducer), Sbig8300M, Baader RGB filters on my trusty GPDX. Processing is with a mix of Pixinsight LE, Photoshop elements 5 and bits of Noel's actions. Would like to now add some Lum data (if I can work out how) and more rgb.

Critique welcome.

Cheers

thats a super start, colour looks good, it just has a slight gradient which can be sorted quite easily

Tried to download trial version gradient xterminator, but no joy. Would it be able to remove the greenish gradient then?

here you go sorted it out

That's much better - Thanks
