Have you considered a 4x or 5x barlow/PM for increased image scale?

Yes, I've considered a 3x Powermate or barlow but I think a more cost effective option is to get a ToUCam! I will get an extra 40% of image scale just by going from 8 micron pixels to 5.6 micron pixels. All at less cost than a decent 3x Barlow or Powermate (or 4x or 5x). If I go for a higher power Powermate with the LPI, the image will be dimmer and I will need longer exposure time - for Jupiter I am taking 0.25 sec exposures now, with a longer focal length I might need half a second exposures which I think will be too long in all but perfect conditions. If I get a ToUCam, not only will I have larger image scale, but I will be able to reduce the exposure time and get more frames!
The only problem is that, after spending up big to get my LX200 last year, and buying some eyepieces, a Powermate, various books, and a 2" diagonal since, the astronomical budget is pretty much depleted - might have a little while to wait for a new purchase!
I hate waiting, but I'll use the time to improve my collimation (still not perfect!) and my processing. I've only been getting decent images for the last couple of weeks since getting on top of capture settings in Envisage and cooling and collimation for my scope. At least now I've got some images that I can try different processing workflows on and maybe approach some of your efforts!

Looking forward to getting the avi to give me something to do when it's cloudy

I'll zip up all the files and upload but I'm a bit hamstrung at the moment. The laptop I use is a 'shared' laptop and is pretty full. I am only processing one directory at a time due to space problems - I split into RGB, process, then delete! I'll zip and upload the ppmcentred files (280x280) - hopefully by the weekend.
