Description

Wasn;t happy with the results of the narrowband SHO, especially as Oiii was pretty non existent, so luckily I foresaw this and had taken some RGB.

Not much in the green channel though as that one kept catching the clouds.

What I did do though was blend the Sii into the blue channel. So this is HaRGSiiB.

3 hours Ha (Baader 3.5nm)

30mins Sii (binned 8nm)

35m RGB totalling, just over 4 hours.

Skywatcher Esprit100 and Atik460EX on HEQ5
