Comet C/2013 X1 (PanSTARRS)

Post by rwilkinson » Sun Nov 01, 2015 7:30 am

Not to be confused with the other Comet PanSTARRS which is currently in Ursa Minor, this is an earlier discovery from the same project which is in Perseus.
It's now around 10th magnitude (rather brighter than the predicted mag 13), and well-placed in the evenings. Last night I managed to detect it from indoors (through my NE-facing window) during a gap in the clouds (though it was still a little hazy):

This comet is heading for perihelion next April, before which its path takes it through Andromeda and Pegasus, so there should be better opportunities to image it over the next few months...

Nice one Ross which mount did you use for tracking?

Cheers Bill

It was a Celestron LCM clamped to my windowsill, the same as I used for testing our new Infinity camera:

But this time holding my TS70ED refractor rather than the telephoto lens.
Even operating at an effective focal length of just 273mm, I had to sit very still whilst taking the images, othrewise every vibration was transmitted through the floor and caused noticeable trails on the picture.

Imaging the comet - inside & out!

Post by rwilkinson » Sat Nov 07, 2015 9:19 am

Last night I took advantage of a couple of breaks in the weather to collect some more data on this 10th-magnitude comet.

First I used my "windowsill observatory", imaging through a double-glazed window:

C/2013 X1 on 6-Nov. 33x 45-sec, using HX916 on TS70ED at f/3.9 on alt-az mount indoors.

But when the clouds cleared again, I set up my tripod and CG5 mount in the garden:

Ross, the Heavens Above website currently shows this comet to be in Pegasus. When I enter the name in the search box in Stellarium it does not recognise it. Is this maybe because Stellarium database is not up to date.

Yes Peter, if you've not updated your comet database since March 2013 it certainly won't be in there.
Here's a link to our previous discussion on this topic:

Thanks Ross,
Every thing up and running now.
I didn't know that I already had asked this question a couple of years ago.

At last, some clear sky! :D
I managed to image the comet for an hour last night, before it disappeared behind a neighbour's roof:
c2013x1_14jan.png
Comet 2013 X1 on 14-Jan. 35x 90-sec using HX916 on SW80ED at f/4.7.

And so I was able to get packed away in time to watch Brian Cox et al on BBC2. 8-)

Re: Comet C/2013 X1 - under the Microscope!

Post by rwilkinson » Tue Jun 14, 2016 7:11 am

I managed to get some images of this comet from Bolton over the winter, but since it passed perihelion in April it's been better-placed in the Southern sky (during their own winter, of course).
It's currently around 6th magntiude, in the constellation of Microscopium, and after a week of failed attempts (due to wet & windy weather in New South Wales), I finally managed to get an image of it from Siding Spring:
