Description

Bubble In Space! Abell 39.

I was capturing more data on my primary target, SH2-290, but it dips below my trees by 2AM, so what to do next with the rest of the evening?

So I found that this small planetary nebula called Abell 39 rises to the east just as Sh2-290 sets. So I programmed NINA to swing the scope over to capture this second target. I got about 90 minutes on this before the clouds rolled in.  Some of it shot through haze, but I got enough for an image.

Shot on the Orion XT12G Dob, ASI2400MC camera, Optolong L-Ultimate using 6 second exposures at gain 400. Image cropped down a bit.
