Description

Was never happy with the original image
https://www.astrobin.com/370867/?nc=user
Could never get the Blue to show up, so decided to have a go with the Equalisation function in Photoshop and this is the result.
Looks a little unusual, but I quite like it.

Original specs:
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.
