The seeing has been exceptional (for the UK) for the last few nights. This combined with the IR Pass filter seems to have helped to create the sharpset Moon photo I have ever made. Additionally, a monochrome camera was used and the combination appears to have made a significant improvement over similar images taken with a OSC camera. This is in fact two photos, the first being one of this evening’s shots of the illuminated Moon and the second another image with a different exposure…

Orion will soon be gone from the sky for another season. I wanted to have a new attempt to produce a satisfactory photogrpah of the bright star-forming region around the Trapezium in the Great Orion nebula which is so…

The ASI662MC has small 2.9 micron pixels which give excellent resolution, especially in a long scope such as the CC. The 10th Jan was the stablest and most transparent evening we have had for weeks if not months and the Moon was really high at over 65° in altitude. The 12th was less clear but still gave a really good view of the full Moon.
