#Mars rising above the lunar limb. This is a stack of 15 frames captured within a 2s interval during the end of the occultation by the #Moon. Captured with a C9.25 Edge HD and ASI678mc.

Early Tuesday morning (9/17/24), the #Moon passed in front of #Saturn. This single frame exposure was captured at the beginning of the occultation at 04:11:35 PDT from San Diego. The image has been adjusted to normalize the difference in brightness between Saturn and the Moon.

Here is the image of the entire #Moon, with the #ISS in transit. This is a single 0.3ms exposure extracted from a video captured with a 6" f/6 Newtonian telescope and ASI183mm camera.

I captured the @Space_Station transiting the #Moon last night. Shown below is a cropped region of a single frame from the sequence (0.3ms exposure). The next post shows the full moon image. Captured with a 6" f/6 Newtonian and ASI183mm. No stacking or compositing. #ISS

This single exposure photograph (no compositing) shows the #Moon and #Jupiter at just over 1 degree of separation. If you look carefully, you can see the cloud belts of Jupiter, detail on our Moon, and three Galilean moons of Jupiter (Callisto is just out of frame).

The image of the South Pole posted above is a cropped region of this larger image, captured on February 4, 2023, at 22:44PST. Check out those rays of Tycho! The distance from Tycho to the lower left of the frame is >1400km.

This is the South Pole of the #Moon, with labels, from an image I captured during last weekend's Full (Snow) Moon. A favorable libration and illumination allows us to see many craters that are difficult to observe. The lunar South Pole is located on the rim of Shackleton.

This image shows #Mars shortly before disappearing behind the #Moon last night. I managed to capture this image during intermittent rain and clouds. With Mars currently under 11" apparent size, the crater Copernicus (on the terminator) appears 5x larger in diameter.
