M27 LRGB 28 Aug 2019

Here's a look at the Dumbell Nebula (M27) taken a couple of nights ago through my C14 with an F7 Optec Telecompressor in train, captured using a QSI583wsg camera and Astronomic LRGB filters

Data was captured using SGP, guided by PHD2/LodestarX2. All subs were 300secs binned 2x2.

L=21 R=8 G=8 B=7.

I wondered whether I'd be able to get the outer halo, which I could just about see in the L stack with a very aggressive stretch, but I don't have enough data to do that justice, so maybe I'll add more later.

Thanks for looking.

Love the scale of the image.  Makes mine look rather wee.

Olly suggested collecting additional data in Ha and OIII to get the outer halo.  I've started on that and will continue as the cloud allows.

Thanks James,

Unfortunately I don't have an OIII filter, just Ha, plus my QSI camera is the 5 FW version, so not easy to incorporate NB anyway. I sometimes shoot Ha for added R, so maybe I should take a run with that as that is loaded in the FW, but I think maybe it's primarily the OIII that's needed.
