  1. So, to follow up: This thread can be closed. I did the job - dead-easy, thanks John - but immediately realised that the focus rod is stiff. I'd never noticed before, but now it was obvious. Torsion would build up in the cable until it was enough to overcome stiction and then suddenly it would make a half-rotation in one jump. Gear cable wasn't even strong enough not to uncoil in the one direction. The brake cable fared better, but I think flexifocusing is out of the question until the focus itself is smoother. I'll see about stripping down and regreasing sometime soon. Looks like the back of the OTA will unscrew once it's deforked. But that's getting a bit off-topic for the classifieds.
  2. Thank you John, that helps a lot. I was wondering if brake or gear cable would do the job. I'll get the cable cutters out tomorrow.
  3. Looking for a flexifocus for my ETX-105. Thanks, Douglas
  4. Down here in the southern Alentejo, Portugal at more or less 37 degrees compared to southern UK 51 degrees North, Sirius is way up high right now, and sparkling like crazy anyway. I love the interaction with the atmosphere, with or without a telescope, but most of all through a telescope way off focus, like a plasma ball, so beautiful!
  5. I can't stand the suspense! How come it's still for sale? I just want to look after this lovely little scope but I'm not so often in London. I'll send you a PM in a bit with some ideas how I could get hold of it. At least then I can rest easy one way or another...
  6. Hi, Looking for a vixen (or other) 36.4mm to 1.25 inch adaptor please - to fit to a Prinz 660 drawtube. Thanks, Douglas
  7. So, if anyone one day needs to know... I'm pretty sure it's actually a B50K 12mm radio potentiometer. About a dollar including post from Aliexpress. Will only know for sure if it fits when it arrives by China Post in a month or so.
  8. Hi, Does anyone know where I can find a suitable potentiometer to replace the brightness control on a GP-DX polar axis illuminator? It's an 850k ohm pot according to the text printed on it - I guess logarithmic - but it needs to be the same size as the original to fit on the PCB and I just can't find one... If someone can tell me what this style is called it should be easy, but they come in a bewildering range of sizes and forms! It needs replacing as a previous owner of the mount left a leaky set of batteries in it for too long. Thanks in advance
  9. Hey welcome Eduardo! I'm also in Portugal - near Odemira, Alentejo. Not into astrophotography though, purely visual. So far I didn't find many amateur astronomers around here. Might help if I spoke a bit better Portuguese! Anyway, welcome to the forum.
  10. Only have a 15mm. And I'm keeping it! But 40 pounds sounds quite fine. Will pm you tomorrow morning for payment details if that's okay?
  11. PM'd you. I'd like this eyepiece please. Douglas
  12. Looking for Bob's Knobs for a C8 (standard 6/32 for Fastar compatible C8 with silver phillips factory screws) 29 dollars seems a bit much for 3 screws, and so does 23 pounds. On the other hands, they would make life so much easier... Anyone have an spare set hanging around, before I checkout?
