Comet 2017 T2 (PanSTARRS)

Post by rwilkinson » Sat Nov 30, 2019 9:14 am

This comet is now around 10th magnitude, moving between the constellations of Auriga and Perseus, so it's well-placed in the evening sky.

It's already showing a tail, and will be brightening over the next few months - potentially to binocular visibility...

The following night I tried it with a colour imaging system: a Sony mirrorless camera on the back of my 80mm refractor.
This is more convenient as it all runs off a battery - I don't need a laptop nor a mains cable.

This comet isn't brightening much at the moment: it's still around magnitude 10. Hence the revised prediction is that it will peak at just 8th magnitude in May.

The Open University's team have recently fixed a scheduling problem with their robotic COAST facility, so last night I was able to catch this fast-moving comet in the small field (33 arc-min) of the C14 SCT. Yesterday morning I'd set the co-ordinates of the comet's position at midnight and when it came to run my job (at 3:45am) the target was still well within the field of view.

Towards the end of this month the comet will pass close to the famous Double Cluster.
This is its position on 27th January:

Sadly the comet is only around 9th magnitude, so it will be difficult to spot even in binoculars; but it should present a good imaging opportunity.

I caught the comet again from my garden last night.
It's a bit brighter than it was in November, but the tail is not as prominent:

Last night I was hoping for an opportunity to catch the comet close to the Double Cluster.
There was a brief clear interval, but once I'd got the 'scope set up and aligned I only managed a single exposure before the cloud (and later fog!) descended again. :(

Last night I used one of the Takahashi FSQ-ED 4" refractors in New Mexico to get an image:

I had another go last night, and managed to get both the comet and Double Cluster within the same field:

But the bright moonlight reduced the contrast, so I didn't catch any of the comet's tail.

This comet is still around 8th magnitude and is well-placed in Cassiopeia.
I took advantage of the clear conditions last night to get a new image:
