Nebulae:

Our galaxy is rich in all sorts of gas clouds. Many of them shine brightly as emission nebulae, others show up as reflection nebulae or as dark patches.

IC 1318 in h-alpha

IC 1318 in central Cygnus.

IC 1396

IC 1396, the Elephant's Trunk. Constellation Cepheus, the King.

IC 1396

IC 1396 with Hubble palette H(SHO).

Messier 1

Messier 1, the famous Crab Nebula. It has a famous pulsar in the center.

IC1805 SHO RGB

IC1805 with 115mm APO in H-SHO representation with some RGB included.

IC 1805

The center of IC 1805 in Cassiopeia, the heart nebula, with the open cluster Melotte 15 which gives much of the energy to the glowing nebula.

IC 1805

Messier 45

Messier 45, the Pleiades, with the Merope nebula and the Maia nebula.

Messier 57

Messier 57 in the Lyrae constellation. The central star shows up nicely.

NGC 7635

NGC 7635, the Bubble nebula. Cassiopeia.

NGC 7635

NGC 7635 in the Hubble scheme of colours.

NGC 2237

NGC 2237, the Rosette Nebula in Monoceros.

NGC 2237

NGC 2237 in Monoceros. The Rosette nebula. Imaged with the Hubble scheme.

NGC 2237 SHO

Detail of the central part of NGC 2237 taken with some short exposures by a 12" f/10 telescope. S 30 min, H 25 min, O 25 min.

NGC 7000 detail

Detail of NGC 7000 in Cygnus.

NGC 7000

NGC 7000 in Cygnus. H-alpha.

NGC 7000

The North America Nebula NGC 7000 in Cygnus. Hubble palette.

NGC 6992 and 6960

The Cirrus Nebula NGC 6992 and NGC 6960. 52 Cygni to the right. In the upper middle we have Pickering's triangle. Actually discovered by Williamina Fleming. This supernova remnant has a huge amount of hydrogen and oxygen rich veils and filaments.

NGC 6992 detail

The northern part of NGC 6992 shows delicate parts of red hydrogen and teal colored oxygen veils. Photographed with narrow-band H-alpha and OIII filters.

NGC 6992 detail

NGC 6992. This is a standard RGB image. The hydrogen and oxygen veils are maybe not as prominent as the narrow bandwidth image. The adjacent star field is very prominent.

NGC 6992 and NGC 6960

The Cirrus nebula in a 30 min H-alpha view.

Messier 97

Messier 97 in Ursa Major.

NGC 281-RGB

NGC 281 in LRGB presentation. Taken under very bad conditions as an experiment.

NGC 281-SHO

NGC 281 in SHO . Very bad seeing. However, you can get something decent anyway. It was haze, clouds, windy and bad seeing.

NGC 281-SHO

An SHO version of the central part of NGC 281. Exposures were 25 + 25 + 25 minutes in S, H, O.

NGC 281-SHO 3x65 min

NGC 281 with longer exposures. 3 x 65 min.

NGC 281 H-alpha

H-alpha image of NGC 281. Five 5-minute exposures.

Simeis 147

Simeis 147 shown in LRGB representation. It is very faint and best seen in H-alpha light.

Simeis 147

Sh2-240, or Simeis 147 in Taurus. A giant supernova remnant, that is somewhat difficult to see. It is so big so it covers about 6x6 full moons in size, or 3x3 degrees. Here the hydrogen clouds have been emphasized, by shrinking the stars somewhat.

Abell39 LRGB

Planetary nebulae Abell39 is rather tricky to observe. It was discovered in 1966 by George Abell. Several galaxies may be seen through the spherical nebulae. The two biggest are at 2 and 6 o'clock, and can be seen as small bluish objects!
