Hi Alistair, Thanks for the encouragement; I use an 8"f5 Newt on an
HEQ5 Pro with 1100D camera. Sometimes I use an 80mm refr.
I have been astro imaging for well over 50yrs, but high quality digital
imaging [actually, the processing] has proven to be well beyond what
my poor old brain can cope with; and my wife gets fed up with all the hours I spend on the computer trying to nut it out, let alone actually doing it. I know I need a coma corrector, but I can't afford one. I can't afford an auto guider either, but I'm actually glad because I can do without the agro of learning to use it and it's associated software.
Incidentally, I know how to embed images, but have no idea how to apply the embedded changes later. The image with embedded changes
shows up in the appropriate file, but is in original form, so I am
having to save images with changes applied.[ I haven't worried about
accurate PA for longer exposures until I get everything else working right,
and no I'm not guiding, although I did manually guide for many many years].
