SkyWatcher Star Discovery 150Pi WiFi AZ GoTo problems

[Giedrius05]

Dear colleagues,

I am new in astronomy and got my SkyWatcher Star Discovery 150Pi WiFi AZ GoTo, however I am experiencing one big problem. When I try to align my telescope using SynScan Pro app on laptop or smartphone the telescope always points wrong direction. I do not have hand controller.

I set telescope north using compass, enter latitude and longitude, but when try to align 1 star or 2 stars, telescope spins way, way off. When the star is in the South East it shows north east, or sometimes points absolutely wrong direction. When it is set on the north and object is 98 degrees east it goes some 30 degrees. It also points lower or higher.

I am totally lost.

I use 8 AA batteries.

What I do wrong?

How to fix this?

Thank you.

Hello and welcome to SGL. The first thing to check is make sure you have your co-ordinates entered correctly. can you post a screen shot of the Synscan app showing the co-ordinates ?

Here are the photos.

Your co-ordinates suggest that you are in one the Baltic states. Is this correct ?

Yes, Vilnius, Lithuania.

Can you use a different power supply to power the mount ? A lot of problems can be caused by an inadequate power supply.

Isn't the Synscan Pro app for EQ mounts, should the OP be using the non pro version instead?

Not necessarily. The basic Synscan app supports alt-az mounts only but the Pro version supports EQ as well as alt-az mounts

Currently I am waiting to buy power tank to be delivered (Sky-Watcher 7Ah Rechargeable Power Tank). It will arrive in a month.

It seems I have found the problem. 

The problem could be with the SynScan Pro app and program for Windows. There should be bug and miscommunication between mount and program/app.  When I used other phone (not Samsung) with Syn Scan app the telescope was pointing to the right direction and height. Tested with compass. This theory still needs to be proved on clear night.
