The California Nebula (NGC 1499)

![1](http://www.psaltery.org/astrophotos/2016/NGC%201499.jpg)

**The California Nebula (NGC 1499)** is an emission nebula located in the constellation Perseus. It lies at a distance of about 1,000 light years from Earth. It is so named because it appears to resemble the outline of the US State of California on long exposure photographs.  (dixit [Wikipedia](https://en.wikipedia.org/wiki/California_Nebula))

To take this photo i used the following setup:
**Scope**: TS Optics ts 80/352 astroimaging
**Mount**: AZEQ6
**Camera**: Atik One 6.0

The total exposure is around 2 hours in october 2016. As my camera is black & white i use RGB filters to build the chrominance layer, and stack several photo on each filter to maximize signal over noise.

9photos of 5 min flitering Luminance except UV
5 photos of 5 min filtering Red
5 photos of 5 min filtering Blue
3 photos of 5 min filtering Green

I used the software Prism 10 to manage the capture, the pre-treatment (Removing offset, dark and flat). The stacking and the post-treatment was done with Pixinsight and at the end Photoshop.
