INDI Library supports Astrophyics range of mounts. Due to the evolution of AP mounts over the years, the protocol used to communicate with the mount naturally evolved. INDI provides three drivers you can select from to best suit your mount.

How to select INDI Astrophsics Driver?

The following table showcase how to select the appropiate driver for your mount.

 Controller Firmware  Driver Executable
 GTOCP2 or older --  Astrophysics Legacy indi_lx200ap
 GTOCP2 E or later Astrophsyics GTOCP2  indi_lx200ap_gtocp2
GTOCP3 & GTOCP4 V or later Astrophysics Experimental indi_lx200ap_experimental

The experimental driver is still under active development and considered in BETA so please use carefully.

How is meridian flip handled?

The meridian flip feature is handled by the AstroPhysics GTO controller. The INDI driver does not handle that logic for these mounts. For this to work properly you would need to be sure to do the following:

  1. The controller has to be initialized with the proper location and time (daylight savings set appropriately, UTC offset, etc.)
  2. If you have a good polar alignment then a one star sync is needed or if you have a rough polar alignment then a 2 star sync will do.
  3. This initialization is done with the hand control or the INDI driver when using your client (e.g. KStars) so be sure you have all the proper settings in the client.
  4. Once this is done properly then your mount will do a meridian flip after it receives a goto command and the object has crossed the meridian. For example if you were imaging an object and during the exposure it crossed the meridian and you have the setting in you client (e.g. the Ekos image tab) set to flip meridian if HA>0 then before the next exposure starts a new goto command is issued to the same object by the client and the mount will know to flip as the controller handles the logic.
