full resolution (8 Mp) M27 was discovered by Charles Messier on the 12th of July 1764. This was the first planetary nebula discovered by him. The name Dumbbell Nebula was given by John Herschel later when he took a better look at the shape of the nebula. M27 is the second brightest planetary nebula …
This image shows the ring nebula together with its very faint halo as imaged by 11″, 12″ and 17″ reflectors. Credit: André van der Hoeven, Terry Hancock, Fred Herrmann, Mike van den Berg and Mathijn Ippel Like other old red giants M57, better known as the Ring nebula, has expelled most of its material in …
In 2011 I started with imaging M57 with my C11 and a 12nm H-alpha filter. I then caught the first glimpse of the outer halo of M57. The ring nebula, as Messier 57 is better known, consists of three structures, the inner, bright and most familiar, nebula, which is about 86″ by 62″. This is …
On the 23rd of May 2013 NASA released a new image from the Hubble Space Telescope and the Large Binocular Telescope showing the outskirts of M57, the Ring Nebula. The same dataset was used as I used for my previous processing of M57. As this was based on comparable data I decided to combine this …
During my holidays in the Eifel in Germany I have been imaging NGC 4725. NGC 4725 is an intermediate barred spiral galaxy about 40 million light-years away in the constellation Coma Berenices. NGC 4725 is a Seyfert Galaxy, suggesting an active galactic nucleus containing a supermassive black hole. Observation data (J2000 epoch) Constellation Coma Berenices …

Discovered 1775 by Johann Elert Bode. Globular star cluster Messier 53 (M53, NGC 5024) is one of the more outlying globulars, being about 60,000 light years away from the Galactic center, and almost the same distance (about 58,000 light years) from out Solar system. At this distance, its apparent angular diameter of 13′ corresponds to …
ARP objects come from the ARP atlas of peculiar galaxies, written in 1966 by Halton Arp. This image shows 2 ARP objects in one field of view in the constellation of Ursa Major. The top object is ARP 214, also known as NGC 3718. It’s a mag. 10.7, 9.2′ x 4.4′ galaxy of the SB(s)a …
