There are some mistakes here, for example, I realized after according to my fits data my light, darks and bias are gain 129 and the flats are 139, however the field seems flat enough.  took a while to proc in PI as each file is a whopping 91.3 megabytes so with my laptop calibration and registration processes chug along like an early steam train.  These were un-binned for higher resolution as would be the binning of choice for galaxy season. I think the Bodes duo is a simple target to get a good image from, but a rather challenging target to make exceptional.  For to to do so I would again likely draw back my integration time, and of course pile on more data. In any case this was more a casual shakedown session w my new camera.

 

I am thinking maybe 240 second lights is saturating the well, as there are no star colors here.  I likely will draw my lights down to 180 seconds.

 

 

Ballyhoo always welcomes C&C.

Here is a L light frame, 240 seconds. Yes there appears to be some vignetting. Maybe larger filters would fix this. Not sure yet.  Seems to proc out ok though.

Great image! I just shot the same target with the same camera at 2x2 binning and I also had stars without color when I integrated it all. I found that using the "Increase Star Color" action in the Astrophography Tools action set for photoshop went a long way to getting the color back into the stars. I applied it maybe 2 or 3 times before I was satisfied. I'm not sure if you use Ps but if you do that would help. See my image here: https://astrob.in/l79p9v/0/

I just ordered the Antila SHO filters for this camera. I am on the fence about which LRGB to order, or whether w LRGB it really matters that much.

It's not just Ha it's LHaRGB
