Hi Meade LX90 users

Which mount do you select when setting up your profile

* Device Hub Telescope (ASCOM)

* Meade Classic

* Meade Generic

* Universal ASCOM for Meade Telescopes?

Hi, I'm not familiar with the LX90 control system, but your driver selection should be defined by the notes for the Meade drivers on the ASCOM Downloads page Of course, you must also install the latest ASCOM Platform 6.55P1 as well.

The appropriate driver seems to depand on the Handbox version (Autostar/ Audiostar or the earlier type - I believe Meade called this Magellan on the LX200 Classic). I'm pretty sure you should not use the 'Universal ASCOM for Meade Telescopes' which relate to more recent systems.

The 'Mount' you select in your PHD2 Profile will depend on whether the LX90 accepts pulse guiding or requires the ST4 system. If your mount has a 'CCD' or 'ST4' port then the Mount selected will be 'On Camera' and the Aux Port will be the ASCOM Meade driver determined as above. The mount will then receive ST4 guide signals from the camera's ST4 port. To allow PHD2 to receive pointing info, you'll also need an RS232 mount connection to an RS232-USB converter plugged into the laptop's USB.

Hope this helps a little.

Cheers,
