AltAz 3 Star Alignment Problems
Posted: Thu Apr 27, 2023 2:32 am
Hi,
I'm trying to get a good star alignment in Altaz mode but am having problems.
I have leveled the mount. The scope is pointed north and level and I have set this as home. I confirmed that the app says "At Home". I select my 3 stars, centering them in the eyepiece and confirming each one. I get the "Success" message at the end. But when I try to slew to an object, even one of my alignment stars, I appear to be several degrees off. Even going back to an alignment star I have the error. I've tried this multiple times and the error always seems to be about the same amount and in the same direction.
I was unsure if I was truly pointed north when at home (before doing the alignment) so I slewed to Polaris and rotated the base of the mount in azimuth to be pointing north. I then slewed home and ran the alignment procedure.
I'm not sure if this matters, but I purchased this mount through a dealer as a customer return. Other than the password being changed (which was more than a little bit annoying/scary) it seems to be "as new".
What am I doing wrong?
Thanks,
Tom
