  1. Astronomy - Stack Exchange If any of you, like me, use Stack Exchange a lot then you'll know it's very useful. Well, now there's a stack exchange for Astronomy questions too! I thoroughly recommend the knowledgeable on SGL to get involved if you're interested. It's no SGL, of course , but could prove to quite valuable to beginners and pro's alike.
  2. Celestron Nexstar 130SLT on eBay (end time 02-Jul-11 22:14:30 BST) Celestron 130SLT Nexstar for £150 on eBay. Collection only otherwise I might have had a bit of this myself. Nothing to do with me, but someone might like it.
  3. SW 200P Newt is my big scope, and today I received an ETX70 bought for portability. As for which I'd use for a quick session - I only expect to use the ETX70 on its own away from my house, otherwise I'll still use both. The other reason for the ETX is the GOTO mount. I plan to use the ETX70 in conjunction with my SW to assist me in locating objects - something I'm not doing as well as I should be.
  4. Hi All, sorry for not getting back sooner. All other EPs work fine and the focuser itself is a RnP type (although it does have a lock screw underneath). Checked that, but not the problem. I have now tried the 6mm in a couple of scopes and it seems the EP itself is must be set in the holder at a certain distance (by which I mean not fully inserted, pull up a bit and then screw the EP locks down). As previously said, I dismantled a 2x Barlow and used it as an extension and that pretty much enables adequate focusing in a refractor - due to the clouds I haven't yet tested this method on the newt.
  5. @Simms - I'd really appreciate that! PM me nearer the time if you think it's possible and we'll try to arrange something. Genuinely and pleasantly surprised by the level of support and character of the SGL members!
  6. Quick update. I tried the 6mm in a 70mm Meade refractor I had lying around. The EP would give me focus once I had adjusted it's position in the holder. The amount I had to pull the EP back was very different to that on the SW200P - giving me reason to accept that the position in the holder is dependant on the scope. I then took the optics out of an old 2x Barlow and used it to extend the distance from EP to scope. This worked, taking the focus from the outer most extreme on the refractor to about half out. Next time I'm out with the newt I'll test the arrangement there too - if it's a matc
  7. Being a muppet hasn't been ruled out! There can't b any elements missing from it as it's quite a simple design (Celestron) and I've never had it apart. I tested the magnifying glass technique on your smiley face above and it works to resolve the RGB elements of a pixel - surprising clarity actually. I tried the focus every which way. I've ordered a parafocalising ring from AstroBoot and that should be here early next week. I'll just have to use it something like the moon to achieve the correct focal distance. While that should solve the problem - it's still a mystery to me why all of a sud
  8. Appreciate the tutorial! I'll get around to making one soon I'm sure.
  9. Here it is: http://stargazerslounge.com/beginners-help-advice/142903-light-pollution-maps.html Depressing.
  10. Equipment is in my sig, but according to a LP map I saw on here a couple of weeks ago I'm in a terribly light polluted area. I'll try and find the LP map and post a link in here.
  11. Odd indeed! I'll try it in another scope as soon as I can. I'll also look into a parafoc-im-a-bob ring too No change in my eyesight, no dropping either (unless somebody else did, if so they're in a bit of bother themselves ) Thanks for your help!
  12. Appreciate everything you have all said, but when I mean 'focus bother' I mean a complete inability to get any kind of focus at all. To demonstrate, here's a quick example of what I mean (through the 6mm): The seeing was awful last night and I wasn't expecting much at all. The above illustration is a when the 6mm is correctly placed in to the scope, only by pulling it p out of the scope a bit could I resolve the shape of Saturn. So, while I expected the view to be rough, I'm concerned that the EP is no longer able to sit properly in the scope. It needs to pulled this way and that to be ab
  13. Hi all, Somewhat optimistaclly I set my scope out earlier banking on clear skies. Ithas since clouded over (boooo) but I was able to get a quick Saturn view in. Trouble is, my 6mm has suddenly decided it won't focus. I've had focus out of it before (I sometimes go mad and stick on a barlow too, not so good focus) and it was fine. All of a sudden I get the light from saturn but no where near focus?!? It resembles a star when you defocus for collimation. And for the record, I haven't collimated. Ever. I have no means for collimation. Could that be the problem? Other EPs seem fine, albeit
