M17 Swan Nebula using Duoband Filter

Further experimenting with my new ZWOASI2600MC and ZWO Duoband filter under Sydney Bortle 8 skies last night
Not a good start , didn’t realise the power pack cord to my laptop was not push in home so the laptop was running on battery and of course I was set up , framed , focused , guiding and capturing M17 whilst inside watching the footy. Came outside an hour later and the Laptop was dead , mount still tracking but lost APT , Stellarium, PHD2 etc . I thought what’s going on here , replugged the power back in and realised what had happened “ dopey always check your power connections”
Anyway captured 2 hours worth of dithered guided subs and darks
Camera cooled to -10C
6” f6 newt on an EQ6-R mount
Orion 60mm guide scope with helical focuser and ZWOASI120MM-S USB3 guide camera
PHD2 guiding around 1 arc sec error
Stacked in DSS
Processed 3 different images in Startools V1.5
Linear RGB
Linear Mono
Linear Compose

One drawback from using a OSC Duoband Narrowband filter is that you loose star colours but at least you get good detail in your DSO.

Early days yet , so still experimenting and learning with this new camera , filter and capture software

Comments most welcome !
