  1. The SX2 is still of interest :-)
  2. That might be, but one would not even think about upgrading the focuser of a 500€ scope with a 500€ focuser. Focusing a 2,4mm eyepiece in a loaded turret which weights 1,5kg is "When only the the best will do!"
  3. Recently I acquired a second-hand FC-100DC with MEF-3. I don't think that the MEF-3 is the optimum, because there is some flex in the sheetmetal plate that attaches to the housing. I expect the FTF micro pinon to be more precise due to less backlash. But certainly since Tak focusers vary quite a bit one might be equally satisfied with his/her copy.
  4. Using a dovetail which is longer than the saddle of the mount usually does not make sense. The geometrical moment of inertia of the FC-100D tube is much higher than that of the dovetail. So basically you allow your setup more flex if your dovetail is too long.
  5. With my DC and DL I use the Primalucelab rings with a 140mm Vixen-style bar. I never doubted the stability of the rings and/or bar.
  6. before asking third party companies, I'd contact Baader Planetarium directly: https://www.baader-planetarium.com/en/contact-us/
  7. As far as I know gen 3 NV-devices are not allowed for exports out of the US. How is the legal situation concerning these Televue/TNVC devices in the UK?
  8. Wanted: Vixen SX2 - contact via PM please!
  9. As an observer who uses the Abbe 32 without glasses, I find the eye relief a little bit too large. The eyepiece has an outstanding sharpness and contrast and gives a very neutral color tone. I'm sorry to hear that you are not satisfied.
  10. good news: Vixen HR 3.4mm
  11. Nice! That's an occasion to change your avatar
  12. For completeness, FC-100DC with FTF2025BCR-LW Focuser and TEC turret and FC-100DL with FTF3035B-A Focuser and Takahashi turret.
  13. That I don't really know :-) They are quite redundant. I wanted to have the DL first and then changed my mind to get the DC. Now at the second production run I could not resist and ordered a DL. In the long run, I want to build a binoscope with two DCs. And then I have the DL as a single.
  14. Some days ago, I received my FC-100DL, which is a complement to my FC-100DC :-) Two wonderful scopes...
  15. Hmm, I don't remember. I think they came like this, but don't know it for sure...
  16. Yes, that's going to ruin me, at least financially! A 125/1200mm Fluorite doublet that has the same color correction as the FC-100DF. . .
  17. I have the LE30, LE7.5, LE5, HI-LE3.6, and HI-LE2.8. I like the 5 and 7.5 for lunar views and cannot confirm the internal reflections. It seems like these internal reflections some people complain about are a thing of the past, and eliminated in the newer eyepieces. So be careful if you buy these used. The LE30 is nice in my opinion, it is very little softer than the Takahashi Abbe 32 with a larger AFOV. It's colour tone is a touch warmer than the Abbe 32, but that can only be noticed in direct comparison. I think the LEs are O.K. for scopes up to F/5 (take care of the exit pupil).
  18. 25585, these focal lengths will result in large exit pupils in fast scopes. What focal ratio do you think about? If you take 7mm as your maximum exit pupil, then you should not go above F/7.1 with the 50mm eyepiece...
