Help needed with my dobsonian synscan

[michaelg]

Hi all

I have taken my dob out this evening for the rare clear skies having set up the synscan I have tried to align the scope but having some issues

When I chose 2 star alignment I chose Capella as my 1st star but when I press enter and it says choose second star the scope slewes before I have even chosen my second star

This is very strange as the scope should not slew until I have entered my second star has anyone had this problem or got any advice

Thanks

Does it slew and then stop, then choose 2nd star?

[michaelg]

I slews and keeps slewing even before you enter your second star as if it has a mind of its own I have tried 2 different power supplies but it does the same thing.

Surely it should not start moving until I have entered my second star

No, shouldn't slew. Sounds like something iffy with the firmware on the handset and/or motor. Is it worth trying a factory reset?

My guess - is it choosing the second star for you, and slewing to it? Once there, you just need to make the fine adjustment to get the star central in the EP.
