  1. I am mostly looking for information about compatibility with C11 optical tubes.
  2. Does anyone have experience with Baader dovetail bars? Especially with BA2451745 and BA2451101?
  3. Does anyone know what counterweights are suitable to use with SkyTee 2 (for both vertical and horizontal axes)?
  4. Is anyone using a Geoptik Vixen Style Saddle Clamp with a heavy optical tube?
  5. Does anyone know if counterweights (3.5kg and 5kg) from SkyWatcher are interchangeable and can be used on EQ3/EQ5/EQ6 ?
  6. I will probably not be able to test the scope at night, but I have already inspected it during the day and it looked in very good condition. Optics were a little dusty, but I was told that they were never touched. I have not tested the electronics, but I think that even if they are not working, I could de-fork the optical tube and use it on a GEM. Don't you think that £1200 is too much for a scope of this age even if in perfect condition?
  7. I will probably be able to test the scope only briefly, but even if electronics are not working or if they fail at a later time, should I consider this as an opportunity for a good price? Any more ideas about what this price might be?
  8. What is a reasonable price for a used Celestron Ultima 11 SCT made in the middle 90s in good cosmetic condition with its original wedge and tripod?
  9. Thank you for your offer, but my location is overseas.
  10. Pricey and without a tripod. I have seen it in person and it looked too delicate for my taste. For about the same amount of money the EQ3 (with the new motors) seems like a better choice, but unfortunately not portable. I had a barn door tracker before but I am looking for a motorized mount now that it is more complicated to build.
  11. I am considering the above mount to use with a DSLR for casual photography of the night sky using short exposures up to around 30sec and lenses up to around 135mm. Does anyone know if the EQ1 mount is suitable for this task? I can also consider the EQ2, but I want to keep the setup as portable as possible and from what I found both mounts use the same motor drives and probably have a similar tracking accuracy.
  12. I know that this topic is about the a5000/a5100, but for anyone interested in these two cameras I would suggest to also consider the a3000 if it is still available. It is not as compact in size, it is made of plastic and has a lower resolution LCD (and an electronic viewfinder), but it is also much cheaper and uses a 20.1 mega pixels Exmor sensor. And as I already wrote above bulb is available in cont. shooting and this is a workaround to disable long exposure noise reduction.
  13. I have the Sony a3000 which I though was not much different from the a5000 and Bulb is available in both Cont. Shooting and BRK C 0.3EV modes. By choosing any of these combinations the camera does not automatically take a second (dark) exposure. And it works with a generic remote cord too. I would like to see the option to disable long exposure noise reduction in the menu, but for now this workaround seems to work for me. I hope this does not make things more confusing.
  14. I am looking for a portable mount that could be used for unguided exposures of 400-500mm focal length and of 1-2 minutes exposure. The FORNAX LighTrack II is advertised to have a peak-to-peak unguided tracking error of around 2 arcsec. Has anyone tried this mount and can advice about its performance?
