Planetary Nebula NGC 1501 in Camelopardalis

NGC 1501 lies in the constellation Camelopardalis (the Giraffe) and is roughly 5,000 light-years away. The internal complexity of this nebula is only hinted at in my image, you can see the various light and dark bands inside. It has also been referred to as the Oyster Nebula, from the bright central star peeking out of the cloudy shell around it. The surrounding cloud was formed when the central star blasted off its outer shells.

Comet C/2016 R2 in Taurus

Here is an image of comet C/2016 R2 taken last evening in the constellation Taurus. The star Gamma Tauri was causing some interference on my focal reducer that I didn’t pick up on until the images were processed, you can see some of the noise and light ring below and to the left of the comet. The comet is near its closest approach to Earth and near its maximum brightness.

ARP 37 (Messier 77) in the Constellation Cetus

Messier 77, also known as ARP 37 (#37 in Arp’s Catalog Of Peculiar Galaxies and NGC 1068 in the New General Catalogue) is a barred spiral galaxy about 47 million light-years away in the constellation Cetus. M77 is the first galaxy in the Arp catalog listed as a low surface brightness galaxy with companions on the arms.

The second image has been over processed in an attempt to bring out additional details in the arms of the galaxy – you can see some of the bright condensation areas around the core.

Walther Crater – December 26, 2017

Walther Crater, on Earth’s Moon, measures about 85 miles across and was named after the 15th century German astronomer Bernhard Walther. I found a reference that stated Walther had a printing press that produced some of the earliest astronomical works.

Montes Apenninus – December 26, 2017

The cold, crisp evenings has made for some really good nights of lunar imaging. The temperature in the observatory hovered around 10F during both sessions. I took advantage of the last two nights to capture some wide field views using a combination of my Canon 6D and ASI290MC with an Antares Focal Reducer.  Here is a view of the Apenninus Mountains, best viewed just after the first quarter moon when they are draped in some shadows. The capture area was 1936 x 1096 and then slightly clipped.
