  1. I'm still using DBE... just how much of a dinosaur am I? (polite answers only!)
  2. Saw three in the East in five minutes a while ago... now 95% cloud, and it looks set in for a while!
  3. Canon 5DIII, Canon 16-35 series2 set at 16mm, f2.8, 2000ISO, 20 second exposures.
  4. After an hour and a half I'd just about given up waiting! I turned around and did some 'light painting' photos in a southerly direction, and then had a look back to the North... Oh my!!! ...fired up the camera and watched... my best ever from Suffolk.
  5. About forty minutes or so of aurora condensed to a few seconds. A few km North-East of Ipswich. It's a big file, but colourful!
  6. Visible to the naked eye as faint creamy colour and very faint vertical shafts. A delight!!!
  7. Since I've 'got into astronomy' I've realised that I had bought the wrong house in the wrong place...
  8. Visited Delabole quarry in the early '80's... a v. big hole! Remember the skies were good.
  9. It's 100 minutes up the A12 from the M25 when the road is clear... therefore normally much longer!!! ☹️
  10. A smashing part of the world... some excellent dark skies once the rain clears!!!
  11. A lovely visit; found it by chance on a trip to Bath a few years ago.
  12. September 17th 2017... Single shots, 5D3, Canon 16-35mm set at 16mm, 30 seconds, ISO 1600/3200.
  13. Added with permission. Same location a few years ago... Thunderstorm on horizon. It really is a cracking spot... apart from the Felixstowe glow!
  14. In Northern Norway I've seen the vibrant colours... In East Anglia (Suffolk) I've photographed the colours and seen nothing!
  15. Thread drift (apologies if offended)... A Harrison clock keyring is so 'unhip' and 'yesteryear'... A few years ago I purchased some of these for my sixth-form students so that they could become better acquainted with 'modern physics'...!!!
  16. 'Triggered' by the 'Stern-Gerlach' thread I've linked to the 'Bertozzi' experiment. When starting teaching relativistic effects I used to show this to the students... behind a few comments about gender, accents, and dress codes there was always admiration for attention to detail and rigour in this video, and a realisation of the meticulous nature of frontier science. https://education.jlab.org/scienceseries/ultimate_speed.html I believe that one of Bertozzi's daughters was awarded the Nobel prize for chemistry. There are some interesting resources from this site.
  17. Monday... 9.0p.m. -9.30 p.m. Sadly I missed Sunday.
  18. Are light pollution filters still needed? Lights just added to the garden behind me... my one piece of 'reasonable' Bortle 4 sky is gone.
  19. Is it visible in the single un-corrected frames? Does it move slightly over time such as light from a street lamp entering?
