I managed to grab another image of the comet from Bolton last night: it's still in Ursa Major, so almost directly overhead.

The adjacent star is BD+48 1971, which is magnitude 9.0, and there was some wispy cloud around during my imaging run: that's why the star-trails appear to get dimmer and brighter.

It's getting bigger and brighter day by day: here's a composite of the latest data from Tenerife last night, using the BRT Galaxy Camera:

Hi Ross
I'm looking forward to one of your excellent colour images. APOD is worth a look today - its a time lapse from the Rosetta spacecraft as it closes in on its target comet 67P/Churyumov-Gerasimenko http://apod.nasa.gov/apod/astropix.html
Regards
Bernie

The comet is in Leo Minor now, heading towards its perihelion in August. I managed to grab a few frames of it last night:

but I noticed that each image was fainter than the last: there was no condensation on the optics, but next door's chimney was obscuring more and more of the field of view! So I'll need to set up much further down the garden the next time I have a go...

I also had a look for it through my 15x70 binoculars. Thanks to SkEye running on my Nexus7 "head-up display" (viewtopic.php?f=10&t=687). I soon found the right part of the sky, but although I could see the adjacent 7th-magnitude stars, there was no sign of the comet. However veen by 11:30pm the sky was still in twilight, and there was a bright Moon too.

It's still just possible to catch the comet, low in the Western sky once it's "dark" (i.e. after 11:30pm).
Last night I set up at the bottom of the garden, and managed half an hour of imaging, although in the last ten minutes a neighbour's TV aerial was getting in the way, and my last image had a clear diffraction-spike from a telephone line!

The adjacent "bright" star is 21 Leo Minoris, which is magnitude 4.5.

Good shot of the tail heading to Leo Minoris Ross
