Hi Fabrizio, 

OK, I am using the joystick, because it seems to work just fine. I'm using it in exactly two ways: to do the   -3 HA  0 DE positioning, then the +3 HA   0  DE position, and in the alignment where I do a goto, then joystick movement to find the star exact position, then push Kstars "align".   Should I be using the GUI mount control on EKOS instead? How are they different?  It is very challenging physically to stare thru the guidescope while moving the mount with a GUI(where I have to look to see the touchscreen buttons). Is it OK to move the mount manually? (unlock the clutch, position, lock the clutch)?

Yes, for your 1
Yes, for your 2, yes, with Kstars
Yes for 3, the star drifts for 15s, then tracking is good.
And yes, immediately, I see that back on Kstars, I have a mismatch on the star on which I just did a "goto"

Thanks

Tom

Hello Fabrizio, 

I can now build the 0.9 code and have that running on my Celestron CGEM DX and Astroberry. After two alignment stars, and a goto operation, the mount completely settles down and it tracks pretty well (about 15 seconds after the mount stops moving, the stars slowly drift, then the stars stop moving. The issue I see now is a mismatch between Kstars and the mount. The attachment shows what I have immediately after a goto to Arcturus. The mount positioned correctly, but somehow the Kstars location before goto and the Kstars location after goto don't agree!

Hi Fabrizio, 

Yes, I think I'm doing as you say. I move the mount thru: 1. A joystick on EKOS 2. The EKOS mount control 3. Kstars goto commands.  Both 1 and 2 resulted in continued fast movement after the commands stopped. But regardless, I'll move to version 0.9. I do the instructions above from Jochym, but there's no output resulting from the git pull.  Then I restart and the driver is still at 0.9.  Do I need to do a make? 

Thanks

Tom

Hi Fabrizio, 

OK, understand, and thank you for the clarifications. I tried that and it seems to basically work (that is after the two syncs, I did a goto to Arcturus and it was fairly close). When tracking see a fairly large amount of drift (approximately 1 min of arc in 1 minute of time). Does the tracking come from the mount or from EKOS?  I also saw a few times where I did a move with a joystick or the SW mount control, and then the mount kept moving after the move command from me stopped.  Is version 0.8 the correct one to be using or should I download the latest? 

Thanks again, 

Tom

Hi I have a CGEM DX. I’m following the Equatorial sync instructions. I’m puzzled by the instruction to rotate by +6 hours HA. If you start at -3 hours HA, this will be a meridian flip correct? But it doesn’t say to change DE. How do I do this?
