ASGT: alignment & calibration stars on same side?       #4410719 - 02/25/11 01:26 PM Edit   Reply   Quote Quick Reply   When interveening obstacles, such as buildings, force you to choose BOTH alignment & calibration stars on the same side of the Meridian, contrary to the manual, what effect does this have on goto accuracy for objects on that same side of Meridian? (e.g. Gotos to western objects when both alignment and calibration stars are also in the west) (Note: I have also posted this question on the Celestron_AS Yahoo group) Post Extras:       Peter in Reno Post Laureate Reged: 07/15/08 Loc: Reno, NV Re: ASGT: alignment & calibration stars on same side? [Re: Terrance]       #4410728 - 02/25/11 01:30 PM Edit   Reply   Quote Quick Reply   I believe calibration stars are designed to compensate any possible mis-orthogonality your scope (OTA) to mount might have. It does not do any good to add calibration stars at same side of Meridian as alignment stars.

[Re: David Pavlich]       #4411575 - 02/25/11 08:25 PM Edit   Reply   Quote Quick Reply   Well, if the obstacles are so great that you can't use ANY stars for calibration, then I guess you won't be missing any objects to observe there either.
