History of astrophotography
The astrophotography has its start over 150 years ago. It was Daguerre who “invented” it in 1839. He took the first picture of Moon with the purpose to create a detailed map of Moon’s surface. That tells us that these days astrophotography was used strictly in science world and was not accessible to everyone.
Later on a lot of invisible phenomenons was discovered with astrophotography, for example Sun’s Corona and a first Celestial map was created.
When the spectroscopy was invented in the beginning of the 20th century there were new findings one after another. Edwin Hubble, one of the most known astrophotographers, spent a lot of time researching the most distant galaxies with this type of astrophotography. He discovered redshift and made a theory that our Space expands which means that a long time ago everything we can see today, the whole cosmos, was smaller. And that’s the beggining of ‘BigBang’ theory.
Anyway, the most known Space Telescope was given the name of this American astronomer – Hubble.
In the first 50 years of the 20th century the whole astronomy equipment was very expensive, but in the 60’s the man called John Dobson decided and made a telescope on its own – with minimal costs. His type of telescope is still very popular and the name is – Dobson.
That’s when telescopes became widely accessible to practically everyone. With minimal costs and some hand skills there is reasonable easy to build-up a telescope. And that’s also the time when amateur astrophotography begun. Firstly there was not a lot photography equipment and tracking mounts were quite expensive but the prices are going down – still today. The last big-boom in the astrophotography was arrival of DSLRs. Every single astrophotograper could afford it and they pusshed away more expensive CCD cameras. The main advantage of them is that they can be used for daylight photography as well and that they assure a good image quality for extremely beautiful astrophotos.
