Alex,
I have now downloaded Registax V4 and the 48 page manual. A lot of reading here in order to understand something of what is going on. I have got a few days to get some handle on the program as the weather forecast for the next 7 days are not too encouraging for a repeat shoot.
Info for uploading an image into a post is in my post #4 in the ' Manual macro on the cheap ' thread.
Superb images in the gallery btw. Something not quite right with my pc settings. Unable to add a comment unless someone else has.
Unlike yours, my scope Nikon ED82A is a fieldscope, well corrected for Astro viewing at 1/10th wavelength, but not good for this sort of thing. See attached pic and laugh
. With the camera adaptor on it is effectively f13. So at the moment I am limited to photographic lenses. 12mm - 300mm, so widefield is the better route.
