A decade on the Board!

I've just noticed that I first registered on this Forum in October 2009, when we set it up (before that we had a rather clunky YahooGroup ). Glad to see that it's still thriving - and not yet been supplanted by other social media outlets! And a big thanks to Carl for keeping it running all that time...

Re: Comet 2018 N2 (ASASSN)

Now it's tracking through Andromeda, and last night was very close to Mirach:

Re: Transit of Mercury

Bear in mind that the Transit starts in the early afternoon, when the Sun is only 18 degrees above the Southern horizon.
And by mid-Transit around 3:30pm it will be down to 5 degrees, so you'll need to be somewhere with a very good horizon to the SW.

Comet 260P/McNaught

Another night, another comet! This one was discovered in 2005 by prolific comet-spotter Rob McNaught (see my article in this month's Bolton Astronomer ). Last month I caught it close to C/2018 N2 in Aries , but now it's moved into Perseus , where it will remain for a few weeks. At last night's Works...

Comet 2018 N2 (ASASSN)

Last night I took advantage of a short spell of clear sky between all the rain-clouds. After its conjunction with 260P last month, 2018 N2 has moved in the constellation of Triangulum , so I had to wait until after 9:30 before it cleared the tree-line. By this time some clouds were coming over, but ...

Re: Comet Africano (2018 W2)

Last night I had another go, this time using my Sony NEX5R camera on my 80ED refractor:

Comet Africano (2018 W2)

I got another image of this comet last night. It's now up to 9th magnitude, and moving quickly through Andromeda.
So quickly that I had to re-point my 'scope mid-way through the imaging run!

Re: Two comets for the price of one?

Last night for once, whilst it was cloudy in Spain and New Mexico, the skies were clear in Bolton!
So I set up a little imaging system pointing through an upstairs window, to catch the comets as they cleared the tall trees in the Park:

Re: Two comets for the price of one?

I've just got an image from an iTelescope in New Mexico:
2comets.jpg
Comets 260P & 2018 N2 from iTelescope T5. 3x 120s with 250mm f/3.4.
2comets.jpg (252.42 KiB) Viewed 674 times
260P is the one near the centre of this field.
This time I was operating the telescope "live", rather than waiting to get the data back from a pre-submitted job.
