California Nebula California Nebula NGC 1499 in constellation Perseus.
Exposuretime: ca. 45 Minutes on Kodak Pro Gold 400 film. 
This is a large cloud which consists predominantly of hydrogen gas. 
Horsehead Nebula in constellation Orion. 
Exposuretime: 60 Minutes on Scotch Chrome 400 film
This is also a cloud of hydrogen gas, which is stimulated to light emittance by the light of stars within the cloud. In front of this is a dust cloud with the shape of a horsehead, which in turn does not emit light. 
Horsehead Nebula
Galaxy M64 Galaxy M64 in constellation Coma Berenice. 
Made with: Celestron 9 1/4.
Exposuretime: 60 Minutes on Kodak Pro Gold 400 film. 
This is an independent star system as our own milky way, which is about 40 Million Lightyears distant. Because of a dark dust cloud which obscures partly the galaxies core, it is also called "Dark Eye". 
globular star cluster M13 Globular star cluster M13 in constellation Hercules. 
Exposuretime: 60 Minutes on Kodak Pro Gold 400 film. 
Exposure taken with: Celestron 9 1/4 .

Globular star clusters are very dense star associations, which consist other than open star clusters, predominantly of old stars. Also other than open star clusters do globular clusters not resolve into single stars, because of their much higher density. This high star density is the reason why humanlike inhabitants on a planet (which is very unlikely !) within such a globular cluster could not make astronomy, because their night would be quite bright due to the numerous stars in the sky. 

Globular star clusters surround our milky way, which has as other galaxies disc shape, in a globular space around this disc. Because they consist predominantly of old stars this is a sign, that the milky way has had also spherical shape in its early stage. This early milky way developes then because of its rotation (around its own axis) into the final disc shape. 

The planetary Nebula M27 (Dumbbell Nebula) in constellation Vulpecula.
Exposuretime: 60 Minutes on Kodak Pro Gold 400 film 
Made with: Celestron 9 1/4 . 
This object has nothing common with a planet, its name is due to its image in a small telescope (a small planet-like disc). In reality it is a gas cloud which was the outer shell of a star, blown away from it when the star was dying. Such processes, especially Supernova explosions of massive stars at the end of their life, are very important because in this way the interstellar gas is enriched of heavy elements (all elements heavier than Beryllium). Those heavy elements are a fundamental requirement for the development of life on a planet like the earth. In other words, nearly all elements which make up our body have been built in the core of stars long ago and have been brought into the interstellar gas, when those stars died.
Dumbbell Nebula
M101 Spiralgalaxy M101 in constellation Ursa Major (big dipper).
Exposuretime: 60 Minutes on Fuji Superia 400 film
Made with: Celestron 9 1/4 . 
This star system with a comparably small distance of about 15 Mill. lightyears can be seen with a binocular as a circular nebula. In its spiral arms one can see many red hydrogen clouds from which new stars are formed. Among them many very massive stars which have, because of their high brightness, only a short life and end in gigantic supernova explosions, which are for a short time as bright as a whole galaxy. Such events have been observed in this galaxy in the years 1909, 1951 and 1970. 
Galaxy M106 in constellation Canes Venatici. Exposuretime: 60 Minutes on Fuji Superia 400 film
Made with: Celestron 9 1/4 . 
This galaxy is surounded by several smaller (or wthin a greater distance) galaxies, one of those can be seen at upper left as an elongated nebula.
