On my Star Sense Hand Control under Telescope,  there is a sub category called Tracking Rate.  Can somebody tell me if there is a default and what should this be set too?

 

I might of accidentally changed the setting and I am wondering if this is causing Planets to drift in my FOV?

On my Evo, I keep it set at Sidereal, and only switch in to Solar or Lunar when needed.

The normal default setting may be no tracking at all....

After each alignment the tracking rate is always set to Sidereal, regardless any previous changes you may have made.

Mike,

 

Thanks for the clarification.  So  I have never changed this value to Solar for the Sun or Lunar for the moon.  Is there any advantage to changing from sidereal to either of these other tracking rate settings ?

---  previous post deleted as my reply didn't make sense in regards to the question.

 

The only reason to use Solar is for tracking the Sun and same for Lunar and the Moon.....

From page 146 of The NexStar User's Guide II:

 

There are three tracking rates:

  • Sidereal – the rate appropriate for tracking the sky’s normal motion due to Earth’s continuous rotation. This is the default setting after the successful completion of an alignment.
  • Solar – the rate appropriate for tracking the Sun’s motion through the sky. This is very close to sidereal rate, and other than during hours of direct, continuous solar observation, you will not likely notice a difference.
  • Lunar – the rate appropriate for tracking the Moon’s motion through the sky. The Moon is a fast mover, as you can easily see by noticing its location from one night to the next. If you plan on observing the Moon for several minutes, selecting lunar tracking will help to keep it centered. That said, don’t forget to return to sidereal when you move on to other objects.

We're using the Lunar rate at the local observatory to drive an SE mount with a heliostat mirror. It's as slow as we can get going from east to west until our special version of TheSkyX that will track at 1/2 solar rate shows up. :)

No worries - half the time I don't remember what I put in it ;-)

My problem with Mike's book is that it is on the shelf at home when I need it outside in the dark.

There is a Kindle version (added advantage of being searchable) but on most devices that will wreck your night vision...

You just need glow-in-the-dark paper or ink.
