My total is 932.2 hours, but about 1/3 is double ups (mono->bicolour->tricolour versions), so my total is just over 600 hours (I did the count on Astrobin).
Interestingly, I approach 300 hours this year, which is nearly a half of what I got in total since starting astro in 2013. It seems that moving to Prossy was quite helpful in terms of astroimaging
