  1. So I take it any extension tube would be ok. Would this one - https://www.astroshop.eu/extension-tubes/orion-extension-tube-1-25-extender/p,14075 - fit into the existing low profile 2" to 1.25" adapter?
  2. Ok, thanks for another confirmation. Time to source the extension.
  3. The highlighted advice worked wonders last night! I racked the focuser fully outwards and then pulled the eyepiece as far as possible and the moon was in-focus with my eye in the correct position. I pushed it back in again and it was out of focus. So as you said it looks like I need the longer adapter - but at least I can start using it. Is pulling the eyepiece out a 'normal' focussing technique? Many thanks for everyone's help!
  4. How did you find that? Your google skills are strong! I can't even find it on there site - I'll contact them tomorrow!
  5. Thanks but £35 for P&P takes the total price up to almost 50% of what I paid for the scope...
  6. Thanks again, everyone! I'm going to try and source one online (who deliver to France). Edit: The seller actually showed me the old focuser and it looked like this - https://www.rothervalleyoptics.co.uk/skywatcher-1252-rack-pinion-focuser.html - which doesn't appear to have the long adapter. So giving him the benefit of the doubt (seemed like a nice guy!) it looks like he swapped over the focuser and perhaps didn't test the new one?!
  7. Hmm, the seller said he's replaced the "old rack & pinion focuser with a Crayford 2" with 1.25" adapter" - maybe he forgot to include it ... Edit: It would make sense why I have to keep my eye at a distance if it is missing the long adapter. Damn! Thanks everyone!
  8. Last night I tried my new (to me) skywatcher 8" dob on the moon. The problem was I couldn't really get the standard 25mm eyepiece focussed on it. I extended the eyepiece focusser all the way out but I then had to keep my eye 10-20cm away from it and at an angle to actually see detail (which was very sharp but almost like looking through a pinhole). Am I supposed to touch or nearly touch the eyepipece with my eye (glasses in my case)? The finder scope seemed aligned as the EP pointed at exactly the same point. The scope was outside for more than an hour before use. The focusser lock was screwed in and the EP was actually moving in and out. I tried with and without my glasses - it seemed better without and I could get closer, but with glasses I had to be more than 30cm away. Is this normal? Do I need a different (LER?) EP? I assumed I would be able to put my eye close to the EP and have a good look at the entirety of the slowly moving moon and not get glimpses of portions of it by moving my head around at an odd angle to the EP?! Hope you can shed some light on this!
