N90 Nebula in Narrowband 41 hrs

Hi Guys

Again a bit rare and dim. Ive not processed too much this time so some noise left.

Also in the pic is young NGC602 star cluster and the top right Nebula N89 crept in due to bad composition.

Nebula N90, in the SMC, click here for big

Ha,Ha,synthetic Green,OIII mapped as LRGB. Ha 27hrs, OIII 14hrs hrs Ha 40min subs bin1, OIII 40min subs bin2.

Taken on an RCOS 10" RC Scope at f9, SBIG STXL6303E Camera and PME mount at itelescopes Siding Spring Observatory.
