Quote:I just stumbled on the Astrosysteme site searching for astrographs offers and it seems that they are making a mount http://www.astrosysteme.at/eng/monts.html , observatory class, advertised as having no PE. Can anyone comment on the specifications and if it is really possible to have no PEC at all? The mount looks good in picture anyway.

Quote:Well I will go out on a limb here and say IMHOGuiding or Adaptive optics are allways needed at focal lengths greater than 100mm due to atmospheric refraction.It has nothing to do with how good the mount tracks. Once you go beyond local seeing good tracking means nothing.
Quote:When I win the lottery, I'll get a few of them! 140 lbs. capacity, and super accurate. What's not to like. You can pre-order one at OPT for about 18000.

atmosferic turbulence effects, which as others
already have stated can be dealt with an AO
To bad these mounts will be incredibly expensive!
None of my kit is part of a two year pay to be part of beta test, that still isn't close to ending.

Quote:The ASA DDM60 is very interesting. Since I live in a fair amount of light pollution the portability of it combined with the essential elimination of PEC should make for a great remote unit. I am really interested to hear any actual use comments from any US users...
I lost count of my scopes. Now I just want mobility. I came, I saw, I bought some interesting accessories, and put names to faces: NEAF 2012, ASAE 2012, SWAP 2013, ASAE 2013.
