I installed the autostar suite on my laptop and configured my LX90 to be controlled by the program.

After alignment I clicked on Andromeda galaxy and clicked slew telescope. The scope came close but it was on the edge of view.  I then manually slewed away and then selected Andromeda galaxy from the hand set and it came up centered. Does the autostar suite use a different location database than the handset? I have gotten my alignments down to where DS objects almost always come up close to centered but when I use autostar it is off

Any suggestions?

Thanks for your help

Gday Yomamma

The handset doesnt use precession and is based on J2000 coordinates.

If the ASSuite is working in Jnow, and sends coordinates to the handset ( vs a target )

then it might expolain the difference.

That said, using a galaxy as a test target isnt the best,

you should really test the accuracy using stars only.

I ran a test and slewed the scope to a couple of stars using the handset and then selected the same star on autostar suite.  The RA and Dec values were close but definitely not the same.  It seemed that the handset values were spot on for DS while the autostar suite values were off a bit.

 

Thanks

Good day Don,

Why do you want to use Autostar Suite to control your LX90? I tried the app once and found it very user unfriendly, if I want to control mine via a laptop I prefer Stellarium because with it you can select J2000 coordinates and its very easy to work with. I think daylight savings time is someting that one should never use for astronomy because it can only lead to confusion, not true time but a temporary quasi time, keep to the true time for your time zone.
