A long night under the stars

Last night was pretty clear, with a big Moon dominating the sky. The seeing was also steady and delivered sometimes stunning planet views.

The EDPH76mm F 4,5 could continue (under the moonlight) it’s capture of the Crescent Nebula in the Swan (NGC 6888). The field of view in combination with the ASI2600MC is 236×157 arc minutes or about 4°x 2,5°. With that large field, also the Butterfly nebula around Gamma cygni filled partially the field;

The original test with 9x60s

Final result with 460×30 seconds or 230 minutes.

Jupiter through the 180mm Maksutov. At the right side it’s clear the planet is not yet 100% illuminated. The shadow of the moon Ganymede was on the planet. I forgot to anchor it for stacking so it’s elongated more than it should.

Jupiter with the C14. I had issues with the B/W images, to combine them properly on a color version.

Craters Atlas (upper right), Cepheus & Franklin (middle right & low) ; C14 F11 QHY5III200M IR ; Atlas diameter is 87 kilometers.

Mare Fecunditatis with the elaborate wrinkle ridge system of Dorsa Mawson.

Chang’e 1 was a Chinese Moon space vessel that crashed in 2009 – as intended – on the Moon’s surface; Chang’e is the Chinese Moon Goddess.

Interesting also is Messier A, a young impact crater, with two prominent impact rays stretching out over the mare surface
