the importance of collimation and flats - NGC253 from Astrofest
This is a real good example of not what to do – bad flats, bad darks for that matter, poor collimation of the hyperstar system and very average processing. One year I might actually get something right – until then practice; practice; practice.
Its only 13 x 150 sec, murdered with a celestron Nightscape camera and a C11 with hyperstar ona eq8 which is nowhere near that poncy 1hr single exposure well focussed and tracked stuff from Allan Gould
Been trying to process old data using different sets of flats and bias (don't use darks routinely with the SXVR M25C, as per Terry's suggestion) - I cannot find the proper matching set. Time to redo a bunch, especially now the temps are increasing again.
Still better image than I have gotten in a long while. GREAT potential there sunshine
I recon that's not bad Dave, at least the stars are white. What you need of course, is more gear. You can't front to a star party unless well equipped , that's the only way to take better pics, and look damb good doing it. More gear Dave

I reckon that Dave needs a pantechnicon for the next Astrofest. And a police escort Not a bad NGC 253, BTW, all things considered

Ah like Marcus has for his motto " he who has the most toys wins"
