Comet 2019 U6 (Lemmon)

Whilst waiting for another opportunity to observe Comet NEOWISE from Bolton, I've bagged another "new" comet using an iTelescope in New Mexico:

Comet Lemmon on 27-Jul. 5x 180-sec with 250mm f/3.4

I might be able to get it from Bolton too over the next few weeks: it's low in the West, heading towards Arcturus.

Re: C/2020 F3 (NEOWISE) - an exceptional comet!

Last night I had another go, this time with the 'scope on my EQ5 mount - after I found a site for the tripod where I could see it "underneath" next door's telephone line (although I had to take our washing-line down!): c2020f3_20jul.jpg By 11:30 the sky had darkened enough for me to use 30-sec expos...

Re: C/2020 F3 (NEOWISE) - an exceptional comet!

Now here's my processed data-set from last night (as the 'scope was operating on a motorised alt-az mount, I first had to do a stellar registration to take out the field-rotation, before stacking on the comet.): c2020f3_19jul.jpg The straight (blue) ion-tail is just about visible, as well as the mor...

C/2020 F3 (NEOWISE) - an exceptional comet!

At last - a bright comet with a proper tail! I got my first view of it last night, low in the twilight in the North. I went out with my binoculars around 10:30 and had a look at Jupiter and Saturn low in the South, but to the North the sky was still very bright. However by 11pm it was dark enough to...

Re: Watch Starlink launch live - at night

The 8th batch of Starlink s (postponed from last month) were launched overnight - if you missed them at 2am you can review the video feed: https://youtu.be/y4xBFHjkUvw?t=773 This is the first night-time Falcon 9 launch I've seen - and even the recovery of the 1st stage rocket on their remote-control...

Re: Imaging comets in the twilight

As it turned out, by the end of May Comet SWAN was fragmenting and so had faded considerably, as shown in this image from 28th May: https://fg-kometen.vdsastro.de/pix/2020F8/2020F8_28052020.htm It took me four attempts to find a location for my tripod where I could aim low enough to reach the comet'...
