  1. Really? That's an ice age for you
  2. I have to disagree with Adrian's post relating to the mount not being able to handle any weight. I would agree with the fact that the mount is less rigid than say something like an EQ8 or an AP mount but the price reflects that. Maybe, Adrian, you are using it visually and is thus more susceptible knocks? That I can understand. For me, I have run it with AA's 102mm triplet refractor (~740mm f/l), an 8" Truss Tube RC (1600mm f/l), and a large format 10" Newt (1200 f/l - it is a custom built carbon fibre and is over 10" longer from the spider to the end so it doesn't need a dew shield, so a fairly cumbersome piece) BUT I only use the mount for imaging.... key point. I have the usual imbalance in RA & DEC which keeps the guiding going very well... The supplied counterweight is sufficient for the 102mm, but the others do need an extra small counterweight adding. All setups additionaly have a Lakeside stepper focuser, an SXVR-H16 camera, a 7 position 2" Bright star filterwheel and a 50mm finder scope + Lodestar. I have guided via the ASCOM driver so it doesn't use the ST4 cable, but I have successfully tested with lodestar -> ST4 cable and into the saddle plate's connector, and then from the connector at the polar scope -> ST4 port at the side of the mount so I am not sure why it did not work for you. As I have participated on their beta program, I do know of a few others who have large 10" or 12" scopes successfully attached but they too are imagers... one chao even ran with his large SCT, a medium refractor and a small guide scope! Bit excessive. The one issue at the moment is the firmware cannot handle a side-by-side arrangement which puts the saddle plate at 90 degrees from it's usual position.... That should change as the firmware evolves. The last thing I will add is, the firmware continues to evolve for both the CEM60 & CEM60-EC versions..... and is getting better & more "accurate" and with more features (I believe cone error correction is yet to be integrated, and atmos extinction is now integrated when aligning on stars) . The ASCOM driver now acts as a hub and supports multiple connections to it (planetarium, camera software, focusing software, etc) and works very well. I am debating whether to bring it to Kelling as there has been quite a bit of interest in these mounts and it is more portable than my EQ6! (with pillar extension).... but I don't want to be seen as an advertiser for any company selling these mounts. Phil
  3. Thanks for answering the Q... I missed it Phil
  4. As no-one has commented.. I feel I will... I have looked through this modded scope, as well as seen the images produced through it.. and I'm not usually a solar advocate but I have to say... it was quite spectacular... As for the event.... really good to have a number of like-minded astronomers in the same place.... and terrific than we got non-astronomers interested at the time.... super Phil
  5. Thanks... got to admit... am pleased with the result, considering it only started out as a quick test last week
  6. I know a number of people who have this scope & use it VERY successfully for great widefield astro photography - good luck on yours
  7. Always a great summer target is Albireo - superb colour double of golden yellow & fiery blue.
  8. .... all my stuff in there is either steel or aluminium.... both are doing well
  9. Very good for a small scope... if you jump to a larger aperture, you def. need a coma corrector
  10. Cool... artificial spikes are a bug-bear of mine
  11. The longer the guided image, the more it will show up any imperfect polar alignment - the chosen guide star will look nice & round, but rotation will ensure around it depending on how far out the alignment is
  12. 1st is def. better than 2nd... 2nd looks over processed. What scope did you use? I assume that's a natural diffraction spike (i.e. you used a newt)
  13. Wow - my god... it's full of stars!
  14. M13 never ceases to amaze me visually.... always great to see
  15. I guess this is a disadvantage of a dome obsy where there is no ventilation.... My roll-off roof has gaps all around which lets the air equalise even when really hot days (wooden obsy get very warm) - never had dew forming inside.
