Well, I managed to get about 2.5 hours of data for NGC253 this time despite all the smoke hanging around Sydney (third light for my home made 200mm Newt). I'm still learning the ImagesPLus software, but I think this is looking a lot better than before, although I think it may be a little blue overall.
- 25 subs (from 31 taken - 6 discarded) at 6mins each - unguided on Paramount
- 200mm at f6.9 / 1380mm (f6 native x 1.15 power Paracorr)
- Canon 400D (unmodified) at ISO400
- ImagesPlus processing applying DDP, curves manipulation, colour balance, wavelet smoothing and unsharp mask.
I have also included an enlarged crop of the galaxy.
