Meade LX-200 Classic 16"

IMPORTANT: PEMPro only works in equatorial mode. Please make sure that you are using a "wedge" or other means to polar align and that " Polar" is selected in the LX200 hand controller's "Telescope: Mount" menu ("Alt/Az" is the default setting).

These directions apply specifically to the Meade LX-200 Classic 16. These directions do NOT apply to the 8", 10", and 12" LX-200 Classic models.

So, to use this procedure please follow these steps:

Step 1: Make sure the LX200 Classic 16 is selected as the mount type in PEMpro's Mount configuration dialog:

LX200-16Setup

Step 2: Connect to your mount and camera control program and use PEMPro's Calibration Wizard to set up all of PEMPro's important parameters. Use "ASCOM" as the movement method.

Since the Classic 16 has a way to get the current index no further steps are required as with the LX-200 GPS.

Getting the PEC curve to the mount

After synchronizing to the mount you can follow the normal procedure for acquiring data and creating a PEC curve. After you have done these two steps you can upload the curve directly to the mount from the LX-200 16 tab. Press the From Created PE Curve button to load the curve . Note that the curve will be inverted if the Movement Direction in the Settings Summary is set to Reverse. If you don't want the curve inverted change the movement direction to Forward in the Settings Summary dialog and press From Created PE Curve again.

This will load in the PEC data from the curve you just created. You can also from this page load the PEC curve from the mount (From Mount) or from a file (From File) . Once a curve is loaded you can write the PEC curve to a file (To File) or to the mount (To Mount). If needed you can also invert the PE curve (Invert). The Smooth button is reserved for future use. It does not do anything at the moment.

So after loading the curve press the To Mount button to finally update the LX-200's PEC. At this point you can enable PEC on your LX200.

Editing PEC Cell Data

You can double click anywhere in the graph area and that will show and highlight the line in the table associated with that point on the graph. Then if you double click the table entry that will bring up a dialog that allows you to manually edit the data. This is what that dialog looks like:

Make your changes and press Close to exit the dialog. Changed values are reflected on the graph and can be written to a file or back to the mount.
