Hi - just a warning about Skysafari 7 either using the INDI connection or the LX200/Skysafari INDI driver, when Skysafari 7 disconnects from the mount, including when the app goes into the background when you hit the Home button, tracking stops.

I've mentioned this on the Skysafari support forum - Skysafari 5 using the LX200/Skysafari INDI driver does not do this and tracking continues even when the Skysafari app is closed or mount disconnected.

OK - I have EQDirect Cable and the results are the same.

Does anyone know if the Skywatcher Alt/Az driver supports the older, servo-based AZ mounts?

Thanks

Hi
I've been using INDI for a few years EQMOD on my HEQ5PRO, however, I've been looking at a travel set up using my AZ Synscan mount and Skymax102 OTA but keeping the flexibility of INDI for remote control from my Camper Van and remote viewing with my Lodestar camera :)

I've tried to use the SkyWatcher Alt/Az INDI driver on my RPi using PC Direct mode with the handset (until I get my direct cable for the Synscan AZ) - I can connect to and control the scope but pointing seems way off. From Parked (Alt=0, Az=0 - North) if  I GOTO Polaris using KStars/EKOS, the mount points to about Alt=33deg where it should be about 53deg for my location.

Can the Skywatcher Alt/Az be used with the AZ Synscan mounts (as shown in the attached picture) and if so do I need to make any changes to the settings to get the positioning right?

The control seems to be there - movement in all directions is as expected, just not the correct amount!

Thanks

Hi

Thanks -removing the no-fits2fits option allows the solver to run, how do I remove this from the options permanently (it reappears each time).

I still cannot use the external solver (I have upgraded to 0.69 which runs OK outside of EKOS/Kstars) - does not appear to find the astrometry.cfg file as specified in the preferences pane.

Cheers

Hi

I've just tried this latest DMG on my Macbook Air running Sierra:-

RPi as INDI server with EQMOD, Lodestar CCD and SPC900 - all connect and work fine, although I've not been able to test under the stars as it's cloudy here (again!).

I've still not been able to get Astrometry working - I have both Cloudmakers Astrometry and Astrometry 0.64 installed under Homebrew.
The Homebrew version uses same index file as managed by the Cloudmakers version.

Both versions can solve captured images however if I try to use the internal solver I get the following:

2017-01-20T20:30:04 Solver failed. Try again.

You must list at least one index in the config file (/usr/local/bin/../etc/astrometry.cfg)

See astrometry.net/use.html about how to get some index files.

Both these are using the "Load and Slew" option with a FIT file that I know both my external versions can solve.

Also changing the solve options does not seem to have any effect - if I clear them all they still get inserted into the solve-field command.

Otherwise a fantastic port - Thanks!!
