Ken, I respectfully disagree.

Image processing (in my opinion) makes up 70% of the final result. Yes you have to use the right capture settings and a well collimated telescope at ambient temperature, but once you get the avi on a hard disk, there's a thousand different ways to process the same data.

And how you process that data can make a huge difference to the final result. If playing around with different processing methods can give me a 5% better image, then in most cases it's worth the extra effort.

If it means I post some images that "go backwards" while i'm testing out different methods, that's fine too. I've no problem with posting less than my best images, if it means:
a) I can find the best method to process my images
b) Others can learn from my experiences

I'm not beating myself up at all. I'm very happy with my original image. These images are simply an experiment, trial and error, to see if different processing methods can yield the SAME result, or a BETTER result.

Very true Steve. I guess you like the VC deconv image because it has a more "eyepiece-like" look about it, where as the others show greater contrast and sharpness than what you see in the eyepiece.

No problems, will do one soon and post it later.

The 1.4x resample used LR, not VC. I agree though that VC can be very harsh. On the VC image I used default 5 and 2.
The "swirly" patterns in the 1.4x is (I think) due to lack of data in those areas, not enough frames stacked or not good enough seeing to increase the image scale.

Thanks for your comments and opinions.
