Venus in the Pleiades

The planet Venus is tracking through Taurus at the moment, and this Friday it will transit through The Pleiades Cluster . I've just been looking at some recent images from the MicroObservatory remote telescope facility: https://waps.cfa.harvard.edu/microobservatory/MOImageDirectory/ImageDirectory.ph...

Re: Online again

What a useful facility this is! Yesterday Keith and I spent a few hours on the channel, talking throught the processing of his comet images. He was sharing his screen so that I could guide him through the required steps in IRIS . And Cheryl joined us for a while, with an update on her use of the DSL...

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 ...
