I took a quick pic of the Christmas Tree Cluster (I only had a limited time before it went behind the house).  The parameters:

 

Scope: Z81 w/ the reducer (448mm)

Mount: EQ6-R Pro

Camera: ASI071MC Pro

Computer: ASIair Pro

Guidescope: ZWO 30mm

Guide Camera: ASI224 MC

Exposure time: 3 min

# of Subframes: 19

Filter: L-enhance

 

I am really liking the ASIair Pro, goto is super trivial with platesolving (it feels like magic to me, this is the first time using platesolving).  I was guiding an average of ~ 0.65" RMS (combine RA and DEC).  I only dithered 1px, perhaps I need to increase this value.  By the way, this was first light for the new imaging rig. These are under Bortle 7 skies with a floodlight in the background (which is not LED at least).

 

I processed this entirely using Pixinsight (except when resizing it to upload it here).  Please be gentle on the processing part, I just downloaded and started using Pixinsight last week (there is a bit of a learning curve here).  I used WBP to preprocess, DBE (wow this works well), I played with some denoising, and did some histogram stretching and curve changes.  I really like Pixinsight, I hope to get better at it.

Fine image!  It's nice to see the neighborhood around the Christmas Tree.  Most posted images are cropped closely and show only the Tree.  It's an interesting area.

Did you use dark, bias, and flat frames?
