I don't think the manufacturer makes you sign a paper stating that you will ONLY use the mount during the day with a PST, lol. GoTo with the capability to initialize using the sun allows tracking during the day. There are no other visible stars to use for alignment. For a portable set-up, this is important, especially when away from a street grid aligned with the compass points, where you could get "close enought" with a non-goto equatorial for short tracking runs. It's just a convenience, Erik. Kurt pointed out that tracking allows more relaxed solar viewing. GoTo makes alignment a snap in daytime. And, of course it could easily be used at night with a conventional telescope attached. On Thu, Jun 11, 2009 at 10:09 AM, <erikhansen@thebluezone.net> wrote:
Unless you are going to look at other objects, like Venus, is there any reason to have goto on a solar mount? A PST for instance can only be used to view the Sun.
