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...

Re: Watch Starlink launch live
