For me the International Space Station passed in front of the moon for 0.6 sec last night. It was 527km away. Stacked video frames from a 6D on a 127mm Mak. #spotthestation

Looking forward to hopefully a successful 7 minutes of terror for NASA's Perseverance Mars Rover this evening. My last Martian 7 minutes of terror was between 5.10 & 5.17am on August 6th 2012 at Natural History Museum. Apologies for shaky camera work! youtu.be/fNXxLiR5dfw

Very surprisingly my 127mm Mak (on a camera tripod) image of the 6.5 day old moon has been shortlisted in the 2021 Royal Museums Greenwich’s "Astronomy Photographer of the Year" competition. #APY13

Whoever at The Times and The Sunday Times who selected this image has never attended a lecture online. Generally lecturers screen share rather than stand in front of a hand written whiteboard.

Very glad the Boeing Space #starliner has docked. The view through my 12in Dob telescope in my back garden at 22.12 UT. It was about 200m from International Space Station . Manually tracked. #spotthestation

So my coffee Huel subscription has been upgraded to coffee caramel. That’s nice. Nicer still to have been informed it was happening in advance. Wonder if I’ll like it? Wonder what I’ll do if I don’t?

Might amuse you, anyone want to try? I’ll give you a clue, quasar is KUV 18217+6419. 3.5 billion year old photons. Taken with #seestar 9 min 10 sec worth of exposures.
