  1. A (UK) seller at abebooks.co.uk has it for £132 which is a little less expensive, although still one too many zeros for my liking!
  2. I found this in the wikipedia discussion for that page: Which would give approx 1.2 billion km, which is nearer to your initial suggestion of Jupiter's orbit!
  3. That wikipedia page bothers me, because it quotes over 1000 solar radii, which is a lot more than 134 million km, then it quotes the 134 million km figure.
  4. UY Scuti's radius is assumed to be approx 1.2 billion km with a margin for error of a couple hundred solar radii, so it's more like somewhere between Saturn and Neptune!
  5. Nicely done Gav, next job, go wider for more faint stuff! As for colour balance, for me you've got it pretty much where it needs to be.
  6. Very nice Avani, as always! You've caught the dome by Promontorium Laplace as well.
  7. Nicely done Charl, nothing but clag here.
  8. Mine is simple, the same as it is most years to be honest. Spend more time observing/Imaging than this year. Tick at least one item off the gear wish list. Read/study/research more. Observe/image at least one new (to me) type of target. Do some outreach. Survive the Meteorological horrors of Lucksall in October. It's intentionally vague to avoid disappointment, and in recognition of the fact that my 'lists' (there are many as with all here present) will always grow in both size and volume, in spite of my efforts to reduce them. Pipe dreams!
  9. That makes sense, I see it now. The 'double' craters are easy - Main & Challis (middle pair) for example, I think the apparent section of double limb is a cluster of craters that normally hide around the other side, including She Shen and Petermann. Notice that Mare Humboldtianum is fully visible as well.
  10. Thanks all. I'm not seeing it (which doesn't mean it's not there). It's definitely not an AP problem whatever it is, I used c. 20k of 'em.
  11. Nice shots, especially the last one. You've captured Plato A, B & O quite clearly and hints of C&D.
  12. Having not captured anything for a month and a half due to a busy schedule and hideous ever present clag, not only did I get lucky with 46p last night I also managed to grab 100 frames on our nearest neighbour. I do love this time of year (when it is clear) with the cold temperatures you have at least a fighting chance of a steady atmosphere and last night was no exception. I stacked 75 frames of the 100 and the result is reasonable. Best viewed full size.
  13. Thanks everyone. I went out and took advantage of the rare clear sky again later as the Pleiades were transiting. Same settings but 100 subs. I've caught a little nebulosity this time as well and the comet colour is more accurate. That nebulosity has brought more noise though so I may reprocess with some masks. I had a good look at 46p with binoculars too.
  14. 50 frames with the Nikon 50mm, 3s, ISO 800, F1.8. It was all rather low down in amongst the local light pollution so I'm rather pleased. I made a hash of blending the foreground though.
  15. Not often one says nice bokeh to a moon image
  16. Handheld, so patiently
  17. And here’s one just after sunrise with the iPhone. ?
  18. Fantastic Neil, love the part where it flies over the Vallis Alpes.
  19. Sadly not, I think I'd need more data to ID them with confidence, which sadly I didn't capture.
  20. until
    After seeing tonight's (11/11/18) close encounter I had a little browse to see if there were any occultations due. There are a few others in the meantime but this one is the first one due that's at a decent altitude. Hope this is enough warning
  21. Here's my one frame that's half decent i wish I’d got it sooner while it was closer but that’s British weather for you
