Messier 51   Leave a comment

Can you do astrophotography from the middle of Manhattan? Vixen ED103s f/7.7 800mm telescope and ASI178MM six megapixel camera. About 45 minutes exposure time.

Four inch telescope above, six foot telescope below, separated by 171 years.

Endymion, Hercules, Atlas   1 comment

Shot August 24, 2021 from Manhattan rooftop using 7″ f/15 Meade Maksutov with 2670mm focal length and ASI533MC Pro camera. Original 3008×3008; Autostakkert trimmed it a bit. That’s Plato washed out at lower left. 125km Endymion has the crinkled shadow center top. With Jupiter at opposition, they have the same width in arcseconds: 48. I used Sharpen AI to aggressively sharpen then added 1.5 pixels of blur in Photoshop. I believe that’s 142km Pythagoras completely overexposed with an extensive ray system on the left.

Kepler and Copernicus Rays   1 comment

I have a new setup for Lunar imaging.  7″ f/15 Meade LX200 GPS and ZWO ASI071 6 megapixel monochrome camera.  Concentrated on the rays of the two craters.

LAC 076: Mare Cognitum, Fra Mauro, Apollo 12 and Apollo14 landing sites, Parry, Guericke, Bonpland Craters   Leave a comment

A near overhead view of Lunar Astronautical Chart 076.  The rays at upper right are from 24km Lalande, found on LAC 077.

A lower view of LAC 076.

A low view from the south of  59km Bonpland, 47km Parry, and in the foreground, 61km Guericke craters.  A portion of 350km Mare Cognitum is on the left, and an unnamed bay of 715km Mare Nubium on the right.  3D model using Lunar Reconnaissance Orbiter laser altimeter data overlaid with Wide Area Camera images.

Janssen Crater and More   Leave a comment

201km Janssen crater and the surrounding area; see Lunar Astronautical Chart 114 and a bit of 127 and 128.  Rimae Janssen points to 79km Fabricius, and in the same direction, 84km Metius.  Crossing Vallis Rheita, 71km Rheita, and the elongated 68km Rheita E.

A lower view of the area.

Quite a close look at 79km Fabricius crater.

A picture of the region I took with a webcam in 2006.  It reveals the striking linear shadow feature discussed on cloudy nights.

Icarus and Daedalus   Leave a comment

94km Daedalus and 94km Icarus craters on the far side of the Moon.  The Wide Area Camera mosaic does not match up at the edges; 180 degrees east is the vertical seam.

Mare Australe   Leave a comment

997km Mare Australe on the southeastern limb of the Moon.  74km Jenner crater is below center.

This is a virtual print of Apollo Photograph AS15-M-2503 generated by the School of Earth and Space Exploration, Arizona State University.

A low view from 110km above the surface looking south.  The rim of Jenner is just visible on the horizon left of center.

A broader, higher view of a 3D model using Lunar Orbiter Laser Altimeter data and overlaid with Wide Angle Camera images.  Jenner is centered.  See Lunar Astronautical Charts 115 and 116 for names.
