  1. A Skywatcher 10" solid tube on the NEQ6 Pro is a beast and not really stable enough for observing even on the stillest of nights - it vibrates at the slightest touch - for AP forget it all together. A 12" would be worse still and a Flextube 12" pretty much unmanageable. You really need a much beefier mount for anything over 10" is my experience. Hth
  2. This is the stuff I use on my 16" dob - Formica Pattern range StarDust HGP Quarry F1782 CW - see here: http://www.idsurfaces.co.uk/c-3379-international-decorative-surfaces-f1782-stardust.aspx It's around the same price and works a dream - see Mapstars 22" dob build thread in the DIY section. If you get some I'll split it with you happily. I need about a third but if there's no other takers I'll do 50:50 with you.
  3. Extenders and barlows do the opposite of reducers - so it wouldn't make sense to use them together. Hth
  4. Great result Paul! Glad your gonna get sorted - and it saves you all the effort of stripping the mount down which you don't need right now.
  5. The thing is - its main purpose is not just a filter holder. It's a self centering T-adaptor with an easy to use twist lock action and non marring compression ring. It just happens to have a thread for a filter inside it too. So that's four features in addition to your single feature requirement. Filter holders tend to be circular and hold multiple filters typically five or seven, and they allow you to change filters for any eyepiece or camera attached and usually used for imaging. Some are mechanical, other electronic. The filter holders for newts are are typically on a sliding tray that fits inside the tube and holds three or four interchangeable filters. There are other designs too that are included in some specialised focusers like e.g. Moonlite. What I'd advise is to surf around the different astro websites to find a more simple eyepiece adaptor. You want a low profile one (so you don't push the eyepiece out of the field of focus) which is threaded for 1.25" filters. Or a 2" to 1.25" one where the 1.25" piece is threaded for filters as well as the 2" part - then you have the choice of both sizes. FLO have a good selection and so too do 365-Astronomy. Hth
  6. Yup - the polar alignment is more important than any of your 4 variables.
  7. That's pretty normal for most average scope instructions Mark - but it's still exciting eh? Congrats again!
  8. Amazing shots - thanks for the link Stu.
  9. Great combination - Congrats Mark and let us know how you get on with it.
  10. I started with the 150P (plain old one) and it was great but I wished I'd had a PDS version at the time. I say go for it but make sure to use it on a steel tripod rather than the wobbly ally ones. I had an ally one and it took 15-20 secs to settle the vibrations down before looking through the eyepiece. Even then you had to be careful not to touch it and start it off again. But it's a smashing ota for observing with, it just needs a solid mount/tripod for imaging.
  11. Very nice first attempt John - clear spiral detail in Bode's, and the Cigar is hard to get detail at the same time - so you done well there!
  12. A few years back my missus pointed out that with the money I spent on fags I could buy a used Ethos eyepiece every month or a new one every two months. So I gave up smoking two years ago. I guess that can be regarded as a big booboo!
  13. You might find what you're looking for on astroboot : http://www.astroboot.co.uk/AstroBoot/bolts-screws-and-knobs-for-telescopes.html Hth
  14. Good luck Scott, and look forward to seeing you back when the time is right.
  15. Yup - a basic EQ5 mount with steel tripod (but no motors) should be in the £125 approx region. The motors will be around £95 for both brand new or £65 for an RA only - but check for online bargains too on the motors - they do come up from time to time. When you see a mount you fancy going to look at - post a link up here and we'll give you some pointers. It might be a good idea to pop down to your local astro soc and have a look at some scopes and mounts so you get an idea of "condition". Hth
