Here's the link for 'Iris" Paul:

I haven't used it very much myself, but it appears to offer many powerful functions. You might be particularly interested in the tutorial "Remove the gradient of the sky background" (the author is not a native English speaker) here:

I'd be interested to know how you get on with Iris.

Cheers,

Nice. Especially like the widefield of Orion & Taurus. Hopefully tonight will be similar.
