Truth is the cubed root of Verbosity.
Quote:For normal observation purposes I think most of us would agree that one can view the Sun or the Moon at Sidereal Rate rather than switching to Solar or Lunar Rates since any such change will go unnoticed to the eye.
Quote:What puzzles me though is your intended time lapse sequence of the Sun. I presume you're aiming to capture the more fleeting prominences in Ha rather than Sun spots, given that the Sun's average rotational period is a very slow ca. 25 days ?
Quote:Also, how do you rate the tracking accuracy of your CGE in general once set up ? Is it permanently sited or do you have to set it up each time you use it ?
Quote:Tom, what 'scope and (DSLR ?) camera combination are you using ? Is the set up "Barlowed" ? Conversely, focal length reduced ?
