so I am outside with scope facing SE, taking eta pictures. My PHD graph is gradually drifting down in DEC, I have tried using auto and guide in south and north only on phd settings-no change
Which axis am I out of alignment with Alt or Az? I am sure it just needs one tiny tweak
help

Hi, Dec drift with the scope pointed SE would need adjustment in elevation.
The meridian star adjustment is in azimuth.

thank you sir, will try that :thanx:
have to say though, my manual guiding seems to be doing alright,- looking at the computer screen.

Nice to be able to put your head in the sky instead of the screen though :)

sorted it out, was able to get a flat-ish RA and DEC graph for 10 minute subs after a tweak of a few degrees.
Best graph I have ever had!
Cheers
