Hi John,
Thanks for your thoughts.
My version of CdC is 3.0.1.4, ASCOM V5.0 with MeadeClassic V5.0.0

I have experimented a bit, results are:

1. Changing coordinate management in POTH ( it was on 'local')does not
change where the telescope goes when driven from CdC, still always
slews to to J2000 coords.

Isn't POTH just an on-screen hand piece + dome control + focuser
control driving the scope via ASCOM. Also acting as a hub for several
inputs. I can find no specific mention of the coordinates setting in
POTH Help, but I understand it only indicates scope capabilities and
does not affect anything.

2. Using the CdC 'Meade.tid' plug-in (not using ASCOM at all), the
scope still goes to J2000.

3. Using the ASCOM driver with HNSky (www.hnsky.org), the scope goes
to 'apparent', as it should.

I think this issue has nothing to do with the ASCOM driver, but with
the coordinates sent by CdC. 
I have ticked the 'Apparent' setting in the CdC setup, whatever I
select makes no difference, ASCOM or meade.tid.
Using 'Expert Mode' with current data: Still slews to J2000, but
calculates correct apparent coordinates as can be seen in 'About xxx'
after selecting an object.

I have posted a report on the Skychart bug_tracker. So far no
reaction. Maybe this is an intentional feature for reasons unknown to
me? There's a bloody awful lot I don't know!
Annoying to some degree, as I have spent a lot of effort to get the
LX200 pointing much better than Meade-usual. And I like the feel and
functionality of CdC a lot.

Cheers
Rudi

that if you connect via POTH there's a setting under "coordinate
management" where you can choose the epoch, or "local".  If you
haven't used POTH before, it acts as a hub so you can have several
programs all connected to the same scope.  So in CdC you use the POTH
driver, and then in the POTH settings you choose the LX200 driver.
