Waning Half Moon

We have recently acquired a good telescope. You can tell if a telescope is truly good or not before focusing it on the stars: if you have 6 or more weeks of cloudy or rainy weather after buying it, it must be a good 'scope!

This is our first attempt at a photograph with the instrument. Although the "seeing" wasn't particularly good. (You could see atmospheric turbulence through the eyepiece) the image is good for computer backgrounds.

This one image is assembled from four taken at one observing session with the same camera settings. Even half of the moon is too large for the telescope's long focal length. Also note that the aperture of the 'scope is rated F/10, but it is reported F/11 because of the central obstruction. (It is a "Advanced Ritchley Chretian" design)
