imaged comet C/2017 T2 near galaxy (Stillwater Lake)

Heard through the grapevine that the Mini-Ralph observatory would be running which was intriguing. I knew comet C/2017 T2 was very near Messier 109. 

When I checked SkyTools, I found it moving away, unfortunately. But another galaxy was nearby. I asked the MRO robot to aim at star GSC 03833 00845 in Ursa Major. A wee bit of multi-tasking...

comet C/2017 T2 near galaxy NGC 3953 in luminance

Luminance only, 60 seconds subexposures, 10 stacked shots. FITS Liberator, GIMP. North is up; east is left. Full frame requested.

Spiral galaxy NGC 3953 is to the south-west, equal in many ways to the comet. About the same shape, similar brightness.

Beyond 3953 is a tiny smudge. That's MCG 9-20-19.

NGC 3931 is a round little patch.

Then there's a needle galaxy further out still. NGC 3917 is at the bottom-right of the image.

East of the comet lies MCG 9-20-51, a very small dim fuzzy.

Lots of teenie galaxies here...

M109 is to the north, out of frame.

That was fun.
