Noisy galaxies from the city
Ok, I know that its probably not a good idea to take Luminance data of galaxies from the suburbs of Melbourne (and with a bit of the moon out), but I needed to play with the new EQ8.
Attached are a rather noisy pair of NGC253 that had 70min of L and an NGC1365 with 100min of L - no sky glow reduction filters.
I tried taking more data of 253; it got smoother, but no deeper. The one thing that this exercise does, is to make you brush up on your flat fielding skills....
VC200L at f/9, QHY9, ASI120MM guider @ 270mm, EQ8
Poor seeing, so binned 2x2
Comments welcome..
Cheers
Maurice
