Lunar images on Feb 5, 2006
by Vern on Feb.07, 2006, under Astronomy, Lunar
I’m working on some of the Astroleague Lunar2 targets and decided to image some of them while I was at it. All images taken with Celestron Nexstar11 with F6.2 focal reducer and a Phillips Toucam 740K camera. Partly cloudy skies, temperature was 34°F, no wind, transparency generally good, though a number of thin clouds drifted through.
Lunar2 target, Cassini A, is a 10 mile wide crater within the larger (35 mile wide) Cassini crater.
Heading south of Cassini to the next Lunar2 target is Rima Hadley, a north south winding rille. This area was visited by the Apollo 15 crew on the 4th US mission to the moon in 1971.

I’ve never imaged the Moon with the ToUcam I have. So if I put my f/6.3 focal reducer on my 10″ LX 200 I would get similar results?

You should be able to. You can image the moon with or without a focal reducer of course. I tend to use a focal reducer as the field of view is wider. Also, effects of air turbulence aren’t as much a problem. I use 640×480 format and record for about 3 to 3.5 minutes. Recording longer than that will result in a file size greater than 1 Gbyte which can cause Registax to crash. Set the gain low and shutter speed to 1/250 or 1/500.

Thanks Vern. I’ll try that next time I am out.
