  1. When an eyepiece undercut is a problem, I use some black tape (the type that is used by electricians) to make the barrel flat. That's it.
  2. With that focal ratio, I wouldn't get anything longer than 31mm focal length. If money is a concern, I would go for a 24mm 82 deg (e.g. Explore Scientific). Alternatively, 31mm TV Nagler, 26mm TV Nagler (second hand market), ES 30mm 82 deg), APM/Lunt 20mm HDC 100deg. If you really don't mind the cost, you could consider a TV Ethos 20mm. Many people love it. Personally, I'm very happy with the APM UFF 30mm.
  3. Hi @foffof, I have both the 3.4mm and 2.4mm Vixen HR on Sale, if you are still interested.
  4. That's quite a long wait! Glad to hear that it's all working well.
  5. Great report Gerry! I was out with my dob on the 30th Dec. Really pleased with the views of M42 and other targets. Also glad to hear that the pushfix adapter is working well with you.
  6. When an eyepiece weighs more than 1 pound, I personally prefer that the barrel is 2". It feels safer on the focuser to me. Having the whole eyepiece set with the same barrel size also eliminates the need of reducers.
  7. +1 for the wheelbarrow handles! My 12" f6 has them too. It is a pleasure to take the cannon outside and inside easily.
  8. As part of my equipment reduction, I'm selling the following items: Vixen HR 3.4mm (like new) £200 Vixen HR 2.4mm (like new) £200 1.25" Lunt Herschel Wedge (prism, ND filter, and wedge housing structure like new. Locking screw requires tapping and threading. Hence the discount) £80 SOLD The Vixen HR are the best eyepieces I have ever owned. A few members on CN matched them with the Pentax XO. No light scattering and incredibly sharp. In my opinion colour tone is neutral and sits in between the Docter UWA and my Zeiss Zoom eyepieces. Eye relief is comfortable if spectacles are not used (which should not at high magnification). The Lunt Herschel Wedge is an excellent tool for white light solar observing using a refractor. It works even better when combined with a Baader solar continuum filter in my opinion. The hole of the locking screw of the solar wedge requires tapping/threading. Apart from that, everything is in excellent conditions, essentially indistinguishable from new items. Caps and boxes (hard case for the wedge) are included, of course. Price includes 1st class RM signed-for. Payment via PayPal (as friends) or bank transfer. Collection from Cambridge also available if preferred. Thanks for looking, Piero
  9. I used the milk carton solution on the central bolt for smoothening the az axis of my SW 8" dob. It works well. Off topic, but something similar can be done to improve the movement of the thumb screws adjusting the secondary mirror.
  10. Interesting thread and I agree with the points raised so far. I bought both new and used in the last years, and never had a problem with items bought in the second hand market. Sometimes, selling can be frustrating though. I find a bit irritating when I advertise something at a honest price and buyers still want to make offers (e.g. large discounts or £5/£10 discounts to cover the shipping costs). Thankfully, most of people just accept a "no", but some can be rather persistent. I remember a member who repeatedly sent me PMs saying that I would never have sold my items at that price, that they would have stayed there forever, etc. I almost had to blocked that person.. Astro gear has become more expensive since June 2016 (.. no comment on causes..), so prices in the used market increased too. To me, this is the main reason why buying/selling in the second hand market has slowed down.
  11. Hi John, I sent you my details. All the best Piero
  12. Sale pending: Ronchi eyepiece and colour filters.
