[BAA Comets] C/2017 T2 visual/imaging opp

[Dave McCracken]

Hi,

I saw the David Swan alert and had a go. This is my first try at a faint object like this. I think the stacking process over approx 45 minute  period has smudged the comet, but it was too faint to use the comet option in DSS.

Also attached, is a Plate Solve screen shot using an Altair ED70 refractor to confirm I was in the right ball park.

David,

Thanks for the reminder. I noticed that it was getting close a few days
ago. It just fits in my field of view. A nice clear, moonless night here
in Chelmsford.

Nick.
