Moonrise

My first try at moonscape, and it turned out more of a task than I expected. I was a day too late to show light on the mountains as well as the moon. With mountains, it's hard to judge when and where the moon is going to rise. The charts and almanacs are useless because they are based upon having a 'flat' horizon.

The 'notch' taken out of the moon at the 'seven o'clock' position is actually a passive reflector built on the mountain in the 1950's. A passive reflector has two large screens about the size of outdoor-movie theatre screens, offset just enough to get TV signals reflected into the valley on the other side of the mountain. These reflectors must withstand mountain-ridge winds in excess of 120 miles-per-hour. These passive reflectors have been replaced by a newer technology called 'translators' which actually re-transmit TV signals from one side of the valley into the other side of the mountains on a different TV channel.

I'll try again later in the year. During this season, the day-to-day change in moon rise time is over an hour, but later in the summer, it's only a matter of minutes, so then I can have more chances to get the lighting just 'right'.

I believe I used 300mm zoom with 2X tele-extender for 600mm focal length or 900mm effective with the Pentax sensor (compared to focal length on full-frame 35mm film. Exposure was approximately 1/60 second, ISO 400, F8)

The moon, tough target! Seems easy until you try it. All I can say is that this is much better than most first attempts!! Great effort!
