Thanks guys. Id like to do proper bigger targets, but Ive done the easy ones I have in my very limited sky view right now, waiting for more interesting stuff appearing over the next mth or so.
Very interesting link Tony, thats what I was trying to describe in another post. I dont think its the same as the random dithering we do with whole pixels steps.
"With so-called pixel sub-stepping, the recording area is moved on predefined paths with a defined frequency.This "dithering", where the travel is less than the size of a pixel"
This also sounds like it would need a very precisely controled stepping device. I wonder if it still would be cheaper than upgrading to a 16meg sensor ? ;-).
I havent tried upsampling before stacking, but PS upsizing works pretty well, especially with filters.
I really should use a powermate or barlow, but the image train setup with it and OAG AO looks like a bleeding nightmare, if even possible at all.
