NGC6820 in bicolour HOO

[carastro]

My 3rd and last image from October Astro camp.   Taken over two nights. 

Dual Rig

Atik314L/WOZS71
Atik460EX/ED80
Both with x0.8 focal reducer
HEQ5
Ha 29 x 600 = 4 hours 50mins
Oiii 17 x 600 binned + 5 x 300 = 3 hours 15 mins

Total imaging time = 8 hours 5mins

Oiii taken with Atik460/ED80 and Ha taken from both cameras.
There is some blue signal in there, but it seems to be swamped by the stronger Ha signal

Disappointingly noisy for 8 hours data.
