I only get a few days per year here in the tropics where it stays clear enough to barely get enough data for the average galaxy. This would be my deepest Cent A to date, the stars top out at about magnitude 18. While it's clear and cool, the air is turbulent though so not as sharp as it could be.
Details: 233 x 1 minute subs, just 7 minutes short of 4 hours, Skywatcher ED100 at prime focus F9, Pentax K-5, HEQ5 Pro unguided, poked out the kitchen window.
I would have gained several more subs if I didn't fall asleep in the middle of it.
Also lost a few subs due to vibration from my cats Rigel and Orion playing around the tripod. But these things happen lol.
