M42 revisited, with a bigger gun

Hi all,

Tonight conditions were much cooler than a few days ago. And I was in for a big surprise. While I would have prefered to have sketched M42 from a dark site last new Moon, conditions weren't condusive to using much magnification. Even at low power, M42 from a dark site is a totally different beast than when viewed from home.

As the sketch progressed, seeing improved. To the point that not only was able to seen Trapezium E & F, but other component stars that are even fainter! Truely remarkable! While I've seen Trap' E & F before, tonight I could count a further 6 additional stars around the Trapezium.

The second attached image is a close up of the Trapezium.

Tonight I added tha circle of death to the sketch to give the piece a little more context on what I could see though the eyepiec.
