Image Description and Details : In the summer months we can capture the wonderful nebulae region in the constellation Cygnus. In this frame the beautiful Crescent nebula and the material from the hot star WR 134 with their surroundings can be seen in full glory. The image is a combination of Ha data and Oiii data. The data was captured from the backyard in the Netherlands.

The rich field of beautiful summertime targets within our Milky Way is starting to creep into view in the early hours of the morning. I decided to wake up at 3 AM to capture an image of the Crescent Nebula. This is the finest detail I've ever been able to capture of it, including both the ionized hydrogen and the faint outer ionized oxygen shell. A Wolf-Rayet star at its core shed these materials when it expanded into its red giant phase hundreds of thousands of years ago, and now its intense stellar radiation is ionizing these outer shells and making them glow...like a giant brain in the sky! :)

Image Description and Details :

Part of the Cygnus constellation, the crescent nebula is located in the immediate vicinity of the star Sadr. Its atypical shape also gave it the name "Euro Sign Nebula" (currency).
On the left is visible the "Soap Bubble nebula", discovered only in 2007 by amateur astronomer Dave Jurasevich.
The image is a composition in the HOO palette, with an exposure time of 37 hours.
Setup DDM60 mount, Moravian G3-16200, Takahashi fsq85.
