Hello Olivier,

You do the capture in 8bit. Normally it is better to use the full dynamic of the sensor for the SHG imaging (where you are looking at the centre of the absorbing line, that is dark). Yes, I know ... 8bt is faster than 16bit.

For the dropped frames ... as song as it is only a few ...

Hello Robin,

Yes, the zenith is at the meridian ... and so it could have some limitation to slew to or from this point.

The other question is ... how GSServer selects the side of pier for a coordinate at the meridian ?
With an equatorial mount, it exists 2 set of coordinates for pointing in the ...

Hello Robin,

If I do the following ...

- start SharpCap
- open the Test Camera 1
- connect the mount (GSServer starts automatically and the mount is in the Home position)
- click the "Tracking" button ... OK, tracking is ON, click on the button, tracking is OFF

Then copy the short script from ...

Hello Robin,

Do you change something in the last 4.1.13314 version ?

When I start the following script:

import time
import clr
clr.AddReference("SharpCap")
mount_name = "ASCOM GS Sky Telescope"
for index, mount in enumerate(SharpCap.Mounts):
if str(mount) == mount_name:
break

SharpCap.Mounts ...

Hello,

Yes, it seems to work only with some delay after the change to tracking off.

First I was thinking that it is necessary to open a camera for the command of the telescope, but it works without a camera open.

Here this code works on my system (GSServer Simulator and ASCOM Sky Simulator ...

Hello,

I found the cause of the problem.

The GSServer does not go to the AltAz coordinates if the mount is tracking.

=> so do tracking = False before the command and it works :-)

But now I found something weird and that can confuse if you start to program ...
The order of the parameters seem to ...

Hello Philippe,

Can you confirm that you use the mount (SkyWatcher AZ-EQ5) in equatorial mode ?

Hello Philippe,

No, I guess it is some conversion error between the AltAz coordinates and the mount RA-DEC.

For the zenith: with an equatorial mount, you can have only 2 orientations of the mount ... tube East pointing up or tube West pointing up.
With an AltAz mount, you have an infinity position ...

Hello,

That is not so easy as expected ...

I have the error:
Exception: Exception has been thrown by the target of an invocation.

I tested with SynScanPro ... it was similar error ... until I set the maximum angle to 90°. After that it was possible to move with SynScanPro.
I changed back to ...

Hello Joan,

Yes, the script for the occultation exists for several years now and it is generally available.
I updated it step by step. It has now some useful and interesting functions.
