  1. Artificially keeping the earth spin at a constant rate by use of hypothetical rocket devices could indeed spare the need for such leap seconds, but it would not not prevent the moon from drifting away from the earth in terms of distance. If we could move the moon closer to the earth so that the moon's orbital period is equal to the earth's rotational period, and have the moon at geostationary position above, say, the mid-pacific ocean , then a] the earth would not slow down in rotation as much ( ok there are other factors other than lunar tidal friction, but they're relatively minor, such as Sun's gravity effects on earth, and the mean frictional forces exerted by dust/meteors/other natural debris falling to the earth) b] the moon would be out of the sky all the time, as viewed from Greenwich line of longitude c] but alas, you'd still have to travel to the mid-pacific ocean to see any eclipse ... so no change to what we're already used to then ... and it would be a very dark eclipse too.
  2. It will help, but often the storm cells are isolated and only cover a small area a few km/miles wide, and not as effective as a cold front passing over. This page might explain the effects on astronomical seeing conditions ... http://rosecityastronomers.org/resources/see_general.htm By the way .. thunderstorm is one word.
  3. Yep, same here in the Netherlands too (I am latitude 52N). It seems the "Summer" months are just cloud, warm rain, and hardly any darkness. The occasional break in clouds always coincides with a full-moon. We tend to get warm sunny April followed by rain / low pressure systems, then October we have nice sunny weather again. Definitely looking forward to Autumn. By the way, only 25 weeks to go until the shortest day of the year ; then the days will start getting lighter again.
  4. hmmm, not sure we'll be as advanced as many of you make out. After all, back in the 20th Century, passengers could fly from New York to London in about 3 hours. With fuel costs spiralling upwards, and less and less people affording the luxury of their own back yard, and continued public apathy to anything that's not on TV, as well as councils being able to turn nightness into daytime using even more power-efficient lighting. I do wonder if there will be any astronomy interest in 100 years or so. I hope I'm wrong.
  5. Well done TractionMan. The wisps of cloud in your pictures seem to enhance the pictures in a way, it kind of brings it into reality. I was clouded out over here.
  6. I guess you mean the forecasted weather *where you live* looks rubbish. Thanks for the link, I'll definately be following that. Cheers, Chris
  7. Yes, looks smart, as David mentioned. Me likey.
  8. hmm, sounds a bit like me, and a few other good people on here. Maybe I'm Neurotypical after-all, but we can still be very rational-thinking, so I guess that would make us a 'neurorational-neurotypical'. hmm, I like the sound of that. On the other hand, you don't have to have aspergers to use stuff like, say Pixinsight (like I do), but I think it helps. Cheers everyone, and Clear skies
  9. I've decided to go ahead and do the mod on my EQ6. Just received the parts, but during the manufacturing of the 12T pulleys, the holes were not centered. I received wobbly pulleys from the factory. Hopefully it was just a one-off, and that others on here recieve good parts. I am going to see if I can send it back and get it exchanged. Annoying because I have it post it back from Netherlands to UK. I'll let you know how my mod goes when I've finished. By the way, did anyone use a reamer to get the bore diameter to fit snugly on the shaft, or did most of you just use a standard drill bit on a lathe? Clear skies
  10. Well, it was this old post with a OSC that convinced me that I must get one of those (at the time)... http://stargazerslounge.com/showthread.php?t=79020 I've since tried Atik 314L mono (lovely camera) and also borrowed an 8300 mono once (which was a disappointment in terms of sensitivity), but I still use the QHY8 OSC most.
  11. Two Hydrogen atoms walking along. 1st atom says, "I've lost an electron!" 2nd atom responds,"are you sure?" 1st atom says, "yes... I'm positive!"
  12. Oh yes, thanks for posting that. Made my day.
  13. Well put Geoff. I was reading through all the replies on this thread and I was thinking to myself "yes... yes... yes, been there, worn the T-shirt , and Oh My Goodness yes, that too". Through my club experiences I've met some very intelligent, witty, fun, interesting people. However the leadership, direction and strategy of some clubs are very, let's say "20th Century". It's interesting to note the rise in popularity of informal observing groups, using the internet and smartphones for coordination. Definitely found myself a home at SGL ; so welcoming, and so refreshingly devoid of the "follow the leader" mentality that is enforced in some clubs I've been to. I think the "health & safety" thing is something that many of us might underestimate when imaging setting up a society. Once after pressuring a club to do more for informal observing sessions and more reaching out to the public, and fighting against a snooty chairman who would talk down his nose about his million $$$ imaging setup, I got frustrated about the lack of action and support for the newcomers and the rest of the community, and one of my friends started doing rather well at starting up some informal observing sessions, gaining popularity very quickly. The local club chairman told us not to mention the name of the local astro society. Interpret that as , 'if you guys have an accident in one of your silly amateur conquest thingeys, make sure nobody sues the local astronomical society.' Sad times indeed.
  14. With the exception of dobsonians, I would imagine that now most scopes are sold for the imager in mind ; and portability too.
