FOVs in software

In response to size of objects and field size discussion on the RASC TC Yahoo!Group, Paul M noted that TheSky and StarryNight offered field of view (FOV) indicators on the screen, helping one planning observing or imaging. He wasn't sure if Stellarium could.

I shared that Stellarium could easily simulate FOVs a couple of ways. My preferred method was to use a virtual telescope, in turn making the software draw open circles over the sky background.

I also pointed out the SkyTools could do this too, circles for eyepieces and rectangles for cameras.
