Interesting Clive. I have the Canon 1-18mm, and like it a lot. I took my milky way shot yesterday with it.

 

I've not used IRIS before, is it free? I did have stacking issues in DSS with that shot..

Yes it's free (you can download it from http://www.astrosurf.com/buil/iris-software.html). It's old (last update 2010) and I believe it to be the precursor of SIRIL. Althoght not entirely, it's mainly command line driven (so is different to today's point and click software) but it has some useful tools (gradient removal, noise filtering, deconvolution etc). I used the QR3 command which is described here http://www.astrosurf.com/buil/iris/tutorial2/doc11_us.htm

Brilliant Clive, I'll have a look later in the week

For an experiment that came out rather well Clive. 👍

A useful exercise, for the real thing (weather permitting) I will now use my tracking mount to save all the phaffing about manually aligning images (unless you know of some freeware that will do it automatically - not an easy job for 'distorted' images seperated by a significant time period).
