Two more Emission Nebulae
Nov 21, 2014 04:34:37 #
Here are two emission nebulae in Cassiopeia. The first one is IC 1805. The star cluster NGC 1027 is at the left edge of the photo while the cluster near center is Melotte 15. The nebula NGC 895 is at upper right corner. The second object is IC 1848 with it's cluster of stars near right center.
Both objects were shot through a 72mm dia Astro-Tech telescope operating at f/5.6. IC 1805 data: ISO 1600, stack of 167 exposures each 30s, total exposure time 1 hour 23 min 30 sec.
IC1848 data: ISO 3200, stack of 63 exposures each 30 sec, total exposure time 31 min 30 sec.

Algol very nice work. I do so enjoy your artform You have been busy as a beaver here of late.
Great job. Where are you that you get all these clear skies or are you processing earlier work?
I have a stack of folders I should work instead of complaining about the bad weather :roll:

I live in a heavy light pollution environment just 30 miles from Atlanta (pop 4 million!!!!!). The only thing I do is that I use a light pollution filter to get my dark skies. It has been clear here, which is usual for October and November but most other months it is the typical south, hazy.Where are you that you get all these clear skies or are you processing earlier work?
