I have actually viewed stars and planets in the daytime.
After very long nights when the sun starts coming up I head off for a final coffee before I pack up.
When I get back to the scope for strip down and pack away the sun is waayyy up and it's daytime. I give the old GoTo's a final few objects and yep, there they are. Stars and planets in broad daylight
Visually they are quite easy to see.
I did try to image them once without luck. All I got was totally white images! I did get some daytime
Moon images though.
To get the stars and Saturn I needed to experiment with camera settings more but I had to go out so I missed the chance and havn't tried again since.
hmmm . . must try that again soon.
