Hi, Chris,
I didn't think the term 'real time' needed explanation. What I meant was what you see when you look through the eyepiece of a telescope. Planetary objects like Mars, Jupiter and Saturn can be seen in color as well as some interstellar objects like the Pleiades cluster, but I happen to enjoy looking at the Orion Nebular, for instance, but in real time all I see is an image in shades of gray, not the glorious colors that appear in long exposures. The long exposures are necessary to gather greater amounts of light, and the larger the telescope equates to a shorter exposure time.
By the way, your name sounds familiar. Were you ever in charge of a new Planetarium that was built in Centerport, Long Island, New York back in the 1970's? I went to Virginia City, VA to photograph the total eclipse back then and was so excited with my results I showed them to the Planetarium director who gave me a tour of the new facility.
