  1. @ksastro interstellar medium average density is 10^6 atoms/m^3, so you must be talking intergalactic. Is that Voids, or in the local group? 12:05 AM Nov 29th from web in reply to ksastro
  2. @ksastro re: 3 atoms per m^3 - is that somewhere in the thermosphere, heliosphere, interstellar space, intergalactic? Or is some average? ;) 11:13 PM Nov 28th from web in reply to ksastro
  3. Support The Space Tweep Society, add a #twibbon to your avatar now! - http://bit.ly/3Zpwlp 10:20 PM Nov 27th from Twibbon
  4. @oceanchick99 This person doesn't like the Celestron CG-5, does have lots of useful info - http://www.astropix.com/HTM... 9:00 PM Nov 27th from web in reply to oceanchick99
  5. @oceanchick99 The tube seems to be pretty similar to the Orion @CatherineQ and you were talking about earlier. 8:14 PM Nov 27th from web in reply to oceanchick99
  6. @oceanchick99 the Advanced GT series C8-NGT looks like a good Tube/Mount combo - $1019. 8:13 PM Nov 27th from web
  7. @oceanchick99 I am becoming a fan of Celestron. Their "price conscious" equatorial mount is the CG-5. $749 by itself. ... 8:09 PM Nov 27th from web in reply to oceanchick99
  8. @oceanchick99 For astrophoto a good equatorial mount is as or more important than the optical tube. And likely to be more expensive. 6:59 PM Nov 27th from web in reply to oceanchick99
  9. @rockteacherjan A person trying to cure their ignorance never drives me crazy. A person who is ignorant, knows it, and does nothing...UGGH! 7:32 PM Nov 25th from web in reply to rockteacherjan
  10. @rockteacherjan GMT based on average Sun straight up at noon from obs. Their atomic clock is UTC. Leap seconds used to keep them close. 7:29 PM Nov 25th from web in reply to rockteacherjan
  11. @rockteacherjan UTC and GMT are same for time zone. GMT is based on Greenwich observatory, UTC is based on atomic clocks; up to .9 sec diff. 7:18 PM Nov 25th from web in reply to rockteacherjan
  12. Just observed ISS and shuttle in binocs. Made out shape/orientation of ISS. 6:27 PM Nov 25th from web
  13. @flighthyperbola Airport asked us not to test on the 7th. They don't have enough people to provide adequate coverage. 11:49 PM Nov 23rd from web in reply to flighthyperbola
  14. If there are microbes in Enceladus plume, thus a second tree of life, what new discoveries about biology and medicine await? 11:35 PM Nov 23rd from web
  15. That would be so awesome! RT @Unstrung if there are microbes in the plumes, could be first time a human machine touched alien life. 11:12 PM Nov 23rd from web
  16. Awww, they aren't going to cover the rest of the burns? :( Goodnight all. LOS, see ya over the hill... 11:18 PM Nov 22nd from web
