Re: Setting up a flat panel target
|
What Paul has described is exactly what I do. The Optec Alnitak flat panel is secured to the observatory wall by one of those television mounts that enables one to pull out and move to the left or
right. The top part of the flat panel sits above the observatory wall by about eight inches. This is low enough to never obstruct the field of view of the scope when pointed to the night sky. The beauty of the Gemini system is that there are a number of different
Park settings available. If you run scripting software, you need to be able to specify which ¡°Home¡± setting to fully automate the process.
?
Having said this, I would prefer to have the flat panel mounted on the inside of the dome of the observatory so that the scope is pointing up at an angle similar to normal operations. The commercial
SCT I have is subject to mirror shift. However, this plan confronts a problem ¨C how to power a flat panel and be able to turn it on and off, etc. when it is affixed to the dome. At the moment, the flat panel is powered by the supply which came with it and
delivers around 270 volts to the panel. Both the flat panel and the power supply must be affixed to the dome, and powered by, say, a battery which is charged up by a solar panel during the day. I am looking around for an electrical engineer who could guide
me through this set up.

If you're using Gemini, one way to do this is to define a Home location pointing at the flat panel. You can then command Gemini to go Home when you need to take flats, or park when you are ready to shut down.
If you do decide to save coordinates, use Alt/Az instead of RA/Dec.
