"People say I'm in denial. I disagree."
Quote:But, what the heck is the king rate?
Quote:I'm just curious as to why the moon stays perfectly centered in the eyepiece when the mount is supposed to be moving at a sidereal rate?
First and foremost observing love: naked eye.
Last but not least, telescopes.
And I sometimes dabble with cameras.
Quote:Tony, the scope I am using is a Skywatcher 80mm refractor on the tracking multi-mount. It is the same scope as the 80mm GoScope you reviewed in The March edition of Sky & Telescope. I forget what magnification I was using but the Moon was entirely in view with just a small line of sky all around it. I left for 15 minutes and when I looked again the Moon hadn't moved at all. Still perfectly centered with the same small line of sky around it. I'm assuming that means the scope is tracking Lunar not Sidereal.
Quote:All I'm trying to do is figure out if my mount is tracking at a lunar rate or a sidereal rate.
