Problem connecting ASCOM mount

[twentymeters]

when attempting a connection to my ASCOM mount I get the error:

Error connecting to ASCOM Mount: Type mismatch

is this something seen before?
let me know if you need more detail

thanks,

Hi Ian,

what sort of mount are you using - it would also be useful for you to post the SharpCap log, which may contain more details of the issue that occurred.

cheers,

Robin,

I'm also having a problem connecting to a Celestron mount via an ASCOM hub with a similar error message. There is no problem when I connect directly to the Celestron without going through hub so don't loose too much sleep over my part of the problem. The Celestron ASCOM driver is the latest on http://www.ascom-standards.org/Download ... rivers.htm

The mount can connect successfully to other software (Sequence Generator Pro, Stellarium Scope).

The log is 42K so I've chosen to past what I think are the needed bits below. FWIW I get an error message when I try to attach the log. It complains that the file has the wrong extension.

Ah, now that's interesting because I have a Celestron SE mount lurking out in the observatory that rarely sees use, but it might be worth dragging it inside to see if it can repro this issue (which - fingers crossed - might be the same issue that Ian is seeing).

cheers,

Robin
