Abell 21

Abell 21 is also known as the „Medusa Nebula“. It is an old and quite large Planetary in the constellation Gemini. Extending more than 10 arcmin in diameter, it has a low surface brightness and hence is visually an object for really large telescopes and also photographically requires long exposure times. Abell 21 is approximately 1500 light years away and 4 light years in diameter.

NGC 6894

 

NGC 6894 is a Planetary in the constellation Cygnus. With a diameter of less than 1 arcmin (appr. 40-50 arcsec) it requires a large focal length and good seeing conditions to reveal some detail. Our image was taken in nights with fairly good seeing (FWHM <2 arcsec).

NGC 6781

NGC 6781 is a Planetary in the constellation Aquila. As common for Planetaries, NGC 6781 shows the two prevailing colors red (hydrogen) and blue/green (oxygen).

M 27

 

M 27 is a Planetary in the summer skies well known as the Dumbbell-Nebula. Deep images reveal both the hydrogen (H-alpha – red) and oxygen ([O-III] – blue/green) parts of the nebula. The image is the first light for our new 30cm (12″) corrected Newtonian Telescope.

NGC 2903

NGC 2903 is a well known galaxy in the constellation Leo and can be best observed during spring time. On deep photographies, this galaxy reveals a nice barred spiral structure. It is believed to be a look-alike to our own Milky Way Galaxy for its general size and the central bar.

LDN 1101/2

LDN 1101/2 are two dark nebulas in IC1396 (well known as the „elefant’s trunk“). Our image is arguably the first amateurs‘ picture revealing the tiny Planetary with the nomination IPHASXJ214032.5+564752. This Planetary has been discovered not earlier than 2009 on professional telescopes‘ images.

M 86

M 86 is another large elliptical galaxy in the constellation virgo. It is located in the close vicinity of M 84 which can be seen hereHere is a mosaik of the two showing their relative position in the sky.

M 84

M 84 is a famous elliptical galaxy in the constellation virgo. It can thus be best viewed in the spring time. Its close twin M 86 can be seen here, and here is a mosaik of the two showing their relative position in the sky.

M 77

M 77 is a nice face-on spiral galaxy in the constellation Cetus. It is a well known object of the autumn skies. Although its core is quite bright the outer spiral arms need several hours of exposure time to become visible.

NGC 5996

NGC 5996 is a rather small disturbed galaxy in the constellation Serpens. We integrated our image as long as 20 hours in total to reveal the faint spiral arms and the zoo of faint background galaxies.
