Race against the Moon:
« on: 09:35:23, 18 December, 2005 »
Hi everyone,
Got out at 5.45 p.m. last night to start imaging the core of M31 before the Moon got too intrusive.  Managed to get 77 minutes total with 15 second subs (yep that's a lot of files to process).  Result is not quite as good as I was hoping for (I was hoping to see more of the brown squiggly bits Rob Gendler got in his M31 core shot).  Oh well, if I can get the other 4 frames it should make a nice mosaic.
All the best,
Greg

Thanks guys,
I think with the other 4 frames it will be quite nice, but I don't think even then I'll be able to capture the whole thing (it's a bit big!).
All the best,
Greg

Excellent contrast there, and the centre's not burned out!

Hi guys,
Thank you.  I kept the centre from burning out Dave by using short 15 second subs - this guarantees that even a single sub isn't burnt out in the core - but it was still getting pretty close.  I used the same "trick" on the lower half of Orion image.  By using short subs and a long total exposure time you get both the depth of the long exposure, together with a resolved trapezium which comes about from using short subs.  It means I don't have to merge a short exposure core with a long exposure image - a process which although it gives detail where it would be missing - leads to an unnatural looking image IMO.
All the best,
Greg
