Hi All,
Imaging? Well, that's probably less than 30 hours.
Actually looking through a telescope? That's another story.
I've been looking through telescopes since 1970 -- almost 50 years. Of that, there's also 17 years of working as a guide at Sydney Observatory plus star parties and other outreach events public & private. There's a little bit of variable star observing and back when I was young, quite a few hours observing, recording and tabulating meteor shower counts. Then there's my own personal observing.
All up, I'd reckon it adds up to somewhere between 5,000 and 10,000 hours at the business end of a 'scope (maybe even a bit more) and that's not counting driving to and from or writing/typing up/sketching observations in my log (analogous to image processing).
My observing log (started in 1995) currently has about 6,900 individual entries pertaining to almost 5,500 objects observed -- and still growing. I have enough material/projects that relate to about another 2,000 things yet to observe.
I'm still not tired of doing it yet.
Best,
L.
