Re: Online Tonight

Yes, Bill and I joined Carl on the "BAS channel" and watched the progress with his home-made auto-guider.
Meanwhile I kept nipping out to check how my comet imaging session on C/2019 Y1 was going: viewtopic.php?f=1&t=1045

The other Comet ATLAS (C/2019 Y1)

Apart from C/2019 Y4 (reported in another topic http://www.boltonastro.co.uk/forums/viewtopic.php?f=1&t=1040 ), the ATLAS programme discovered another comet a couple of weeks earlier, last December. This one is also around 8th magnitude, but not so well-placed in the sky at the moment: it's sinking ...

CG5 tripod head repair

Last night I had a problem whilst trying to polar align my Celestron CG5 mount on its tripod: no matter how I adjusted the Azimuth-setting screws, the mount head didn't move. I eventually realised that the two screws were tightening against each other , rather than the registration pin which protrud...

Re: Comet 2019 Y4 (ATLAS)

I had another look at this comet last night, this time using my vintage Starlight Xpress Mx716 camera on my C8 telescope. Things didn't start too well, with a mechanical problem on my tripod (the registration pin had sheared off, but I soon replaced it with a piece of studding and was up and running...

Re: Starlink's "string of pearls"

Tonight may provide a good opportunity to look out for the train of satellites which were launched on 7th January. They will be passing almost overhead in the early evening, with predicted magnitudes around 3-4. For example, this is for STARLINK-1119 : PassSkyChart.png Look out for it passing Venus ...

Re: Comet 2017 T2 (PanSTARRS)

This comet is still around 8th magnitude and is well-placed in Cassiopeia.
I took advantage of the clear conditions last night to get a new image:

Comet 2019 Y4 (ATLAS)

This comet was discovered by the ATLAS program ( https://fallingstar.com/home.php ) last December and has recently brightened up to 9th magnitude. It's in Ursa Major at the moment, having passed close to the M81 & M82 galaxies last week (when it was cloudy!). Last night it finally cleared, so I mana...
