Hi all
Yes like David said its good to see people doing different things in Astronomy. As for how long to stay outside observing, well that’s up to the individual. After all it is something to be enjoyed and when you’ve had enough you come in! It doesn’t make anyone less of an Astronomer even if they only spend an hour or two observing/imaging or what ever. I believe that anyone who really loves Astronomy is thrilled when they are out under the stars. I myself feel as one with the universe out under the firmament even here in light polluted Sheffield!
