Lunar Images with the Orion 10" f/3.9 Newtonian Astrograph February 20, 2016 Uploaded 2/24/16 South is up in this image, more info below.
Perhaps the best way to test out the resolution of a new scope is during the full moon period, when you can try your hand at high magnification lunar close ups. While the 10 inch was purchased specifically for imaging faint comets and deep space nebula with its fast optics, it performed very well on the moon and jupiter, and despite the very unstable seeing which produced high frequency jiggling across the entire image, the stacking software Autostakkert was able to extract the few good moments as seen here. Resolution is near half an arcsecond for this set. (The same night I was able to image surface details on Ganymede with the same setup!)

Left: Three part composite of the limb of the moon which I was imaging. The right side here is right on the verge of shadow and offered excellent contrasts and shadow details in what for me is normally a seldom photogrphed region.

Left: The unusual elevated formation just right of center is "Rumker". Such a low profile is best seen like this right near the terminator with low lighting.

The diameter of this formation is 70km.

Left: The brilliant big detailed crater in the middle is "Aristarchus" with the huge Schroters valley just under it.

Left: Just to the right of the crater Reiner above center is the very strange white area called "Reiner Gamma". It is a mystery as to how it formed, I have heard two dominant theories - one is that it is a comet impact site. Second, it was a site of elevated dust from static electricity. We must go there to be certain.

Left: With Reiner Gamma near the bottom. We have on the limb the two large craters in the rising sun Cavalerius and Hevelius

Left: Wargentin - between the two huge flat bottomed basin - Schickard and Phocylides we find a crater filled to the brim with lava. That is Wargentin!

Left: Panning to the north limb, a region of burried craters with a plaster of paris look

Left: I shot this south polar region on the moon because of the hug mountain I saw on the limb on the left side here. Look how Malapert Mountain stick above the limb and shows superb detail on its flanks. The huge crater on the lower right is Clavius.

Left: Highly cropped close up of Malapert Mountain. The patterning here is processing artifacts.

Left: Messier A and B - two rayed craters from a double impact at a grazing angle. While not on the limb, I normally cant see the moon from the observatory when they are - when the thin crescent moon is hanging low in the western sky.
