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

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

I did manage to catch this comet last night - but only just!
It took me two attempts (including carrying the tripod fully-rigged with 'scope and counter-weight!) to set up in a position where the comet was above the roof-line - and even then I only had ten minutes before it "set" behind a chimney!

It's faded down to 11th magnitude now; looking low in the sky through faint cloud, I could hardly detect the comet on my individual 1-min exposures, but my "invisible comet-stacker" came to the rescue and revealed it as a static blob against the trailing stars:
Comet Lemmon on 9-Aug. 9x 60-sec with Mx716 on C8 at f/3.5

This comet has faded down to 12th magnitude now, although it's higher in the Western sky than last month.
Last night I caught it between the wispy clouds, before it disappeared behind a neighbouring roof.
Comet Lemmon on 17-Sep. 17x 90-sec with Mx716 on C8 at f/3.5.
