Description

A bit disappointed with this one. Shot about 3 hours on 4 consecutive days this week with no clouds but below average seeing, I tried various exposures and gains using experience with the gear and SharpCap's sky analizer. Ended up with 280 lights at an average around 110 seconds at unity gain of 121 with brightness of 4. I guess the humidity is the real deal breaker here in the new backyard.
