While processing my M45 data from a couple of nights ago, I turned on Camtasia and just recorded the whole thing. I edited for time and added a few annotations, so this could serve as a decent demo of the whole process for folks who are new to the process.
Any feedback is welcome!

My final first draft: http://i.imgur.com/oeNgR.jpg
I think I'll give it another round at some point to try to draw out the deeper faint dust.

Haven't watched the video yet (thanks for posting) but the result is excellent!

I looked at the video, it is very good and convenient (I may need to go back and pause at time).
It is nice that you have shown some 'real-life' problems and reprocessing of history. Many tutorials give the impression that processing an image is just a linear process.
Thanks for the effort.

Jlake,
Thanks for the video! It's amazing how much information can be conveyed by this means, and it is enhanced by your pithy comments. One of these days I plan to play it again with a few pauses at places I am not clear exactly what you did. Maybe quite a few pauses.
The result is an image to be proud of.

Jlake,
That video was amazing, this is going to save me loads of time. I am very new to PI (my first post here) and just spent the last two days wondering why I have a multicoloured background and how to get did of it. You had just the same issue, perhaps this is normal? Now I have some idea on how it's removed, I hope.
If you still have the full in realtime length video, I would love to watch that through taking in all the steps, as others have said, it's just too fast to take in.
A fantastic result!

Thanks, Mike, I'm glad it was helpful (if too fast!). I think I scrapped the hour long original screencast, unfortunately.
Tell you what, if you want to host your raw data or master frames somewhere (I use Dropbox), I'd be happy to try a recorded run-through using your actual data. I'm not sure what kind of results I'll get, but I'll run it through one of the 'normal' process runs. That way, you can follow along exactly and then modify it to your own liking.
Let me know if you're interested, I'm at rootlake AT gmail.
To your finer point, yes, a discolored background with gradients is pretty normal, at least for data I've worked with. These can come from non-perfect flat fields, sky glow and light pollution, and other issues. That's the beauty of ABE and DBE in PixInsight -- they model the background variations very well and then remove them beautifully. It's always my second or third step.

jlake,
This is a fantastic offer. I have sent you an email.

Any chance you can make this new tutorial available too? It would be most appreciated.

Sure, I could screencast it when I get the master. It turns out that debayering was not turned on for the Batch Preprocessing, so he's going to do another run.
In the meantime, I made this video yesterday for the Inside Astronomy Forum: http://www.youtube.com/watch?v=1JZi63MBpMw&list=UU35JHxxroGRGZ7h8RGrD6dw&index=1
Nothing revolutionary, just following Vicent's workflow video more or less. Warning: I did not use Background Neutralization or Color Calibration on the RGB, and I should have.

jlake,
Really great videos, nice to see how fast you are able to process! Still a long way to go...
Thanks!
