California Nebula

The California Nebula is an emission nebula in only 1500 light years distance (it's in the Orion arm of our milky way - the same arm that we are in).

This was my first mosaic - I did it with Pixinsight. Overall exposure of this image is 12.7 hours (3+ hours Ha, 5 hours OIII, 4.5 hours SII).

Unfortunately, I am still fighting with vertical and also horizontals stripes in my images. You can see it in the lower right corner. But apart from that, I quite like it.
