Astrophotography 101: Elephant's Trunk Nebula, Part 1. Astrophotography process.

Описание

This is a series of two videos showing my whole process of Astrophotography from my Bortle 8 backyard in Oslo, Norway.
Join me in exploring the powers of N.I.N.A imaging software, PHD2 guiding, Stellarium and also some obstacles being dealt with over the night of imaging!
I made this video for those who want to see how an imaging session runs out, from setting up my eqipment, to polaraligning, focusing and getting the softwares to work togheter!
I also shows how I adjusted my off-axis guider to get the best stars I have seen in PHD2 while imaging with an OAG!

This first part is all about how my night starts from putting my telescope on the mount to my frames get captured and downloaded.
Part two will be all about the editing and processing that was done, this was a really hard one to process. But more on that later! :)

The Elephant's trunk nebula is about 2500ly from earth, and in this time of the year it's visible early in the south from my backyard. Since my view is 180degrees with just some limitations as to how low to the horizont I can image this is a nice target to just let go trough the night.

Wikifacts:
The Elephant's Trunk Nebula is a concentration of interstellar gas and dust within the much larger ionized gas region IC 1396 located in the constellation Cepheus about 2,400 light years away from Earth.[1] The piece of the nebula shown here is the dark, dense globule IC 1396A; it is commonly called the Elephant's Trunk nebula because of its appearance at visible light wavelengths, where there is a dark patch with a bright, sinuous rim.

The Elephant's Trunk Nebula is now thought to be a site of star formation, containing several very young (less than 100,000 yr) stars that were discovered in infrared images in 2003. Two older (but still young, a couple of million years, by the standards of stars, which live for billions of years) stars are present in a small, circular cavity in the head of the globule. Winds from these young stars may have emptied the cavity.
