The camera used was a Canon 5D MarkII 21MP. The lens was a 16-35m F/2.8@F3.5
14 second exposure at iso 3200."
Ellison Chan commented on Kenneth Duffek's blog post Night Ops"I love how well the stars show up. What camera did you use? The dynamic range seems to be very good."
Kenneth Duffek commented on Kenneth Duffek's blog post Night Ops"Hi Dave,
Without telemetry I am not sure but my estimate is around 3mi/hr or 264 ft/min. Not very fast."
Kirill commented on Kenneth Duffek's blog post Night Ops"Awesome photo! This is the best night photo of a copter I've ever seen."
Greg Fletcher commented on Kenneth Duffek's blog post Night Ops"I would think that at high altitudes you would need to run a higher kv motor, and a larger diameter and more pitch. The math gets complicated i guess(if you don't know it that well), but I'm sure the solution could be optimized for thin…"

What motor, prop, and batteries are you using for your 10,500 ft flying? Have you done any heavy lifting with your Hexacopter?
Thank you."
Aaron Curtis commented on Kenneth Duffek's blog post Night Ops"Wonderful photo, and encouraging observations! I'm about to attempt to fly my arducopter quad on Mt Erebus in Antarctica, around 12,500 ft. However, the atmosphere is thinner in polar regions so the pressure altitude is around 14,000 ft…"
me commented on Kenneth Duffek's blog post Night Ops"I should also say that that's an awesome shot and good research. Thank you for sharing!"
me commented on Kenneth Duffek's blog post Night Ops"So to clarify, you started at 10,500 ft and climbed to an elevation of 10,550 ft, meaning that you were only 50 feet off the ground (50 ft AGL). I think we should be very careful with standards and reporting altitude on here. My first time through…"
Kenneth Duffek commented on Kenneth Duffek's blog post Night Ops"Hi All,
Thanks for the comments. The Observatory is located in Arizona atop Mt. Graham. This is the Vatican Advanced Technology Telescope my day job. The location at which I was standing is 10,500ft. I have measured the Hex verticle climb…"

Hi all,
I just wanted to share this. The photo is of my Hexacopter running Ardupirates r527 code. I was testing the altitude hold and flight characteristics at 10,500ft elevation. Well, more like 10,550 from the photo. The Hex flies great and the altitude hold works perfect not mention the battery life is quite descent at this altitude. Usually at an elevation of 2,300ft…
