First Quarter Moon

Moving Along the Terminator

The unusual clear, cool, low humidity weather on June 26 lingered from morning into evening. A nice first quarter Moon beckoned me to set up my Celestron-8 telescope and try some lunar imaging along the terminator. Good observing conditions don't last long in Lynchburg! About 30 minutes after starting work some clouds began drifting across the Moon. But I did get enough pictures to make this 9-image mosaic running down the length of the terminator. Notice the linear feature near the top, but ignore the imperfect section in the mosaic.
Can you find the fuzzy section? I hope not! (Click for full detail.)
This individual image shows the linear feature called the Alpine Valley. Notice the long shadows cast to the left by mountains below the Alpine Valley.
The Alpine Valley just left of center. (Click for full detail.)
Finally, this image shows Mare Serenitatis at upper right and an odd, oval-shaped depression called Rima Hyginus just left of center at the bottom:
The Apollo 15 landing site is near the mountain range on the upper left. (Click for full detail.)

People say I'm crazy doing what I'm doing
Well they give me all kinds of warnings to save me from ruin
When I say that I'm o.k. well they look at me kind of strange
Surely you're not happy now you no longer play the game

People say I'm lazy dreaming my life away
Well they give me all kinds of advice designed to enlighten me
When I tell them that I'm doing fine watching shadows on the wall
Don't you miss the big time boy you're no longer on the ball

I'm just sitting here watching the wheels go round and round
I really love to watch them roll
No longer riding on the merry-go-round
I just had to let it go
