Firstlight of my Moravian G2 8300 with internal filter wheel. It was a lot of playing with camera and also getting familiar with the software etc. I thought i got the right focus, but obviously i didn't. In addition, the L-part of the image was taken with the UHC filter, at almost full moon. However, i am happy with the first result!
Due to the moon, the L-part was replacedby the UHC filter.
The RGB images were taken at first, before the moon came up. Each channel was exposured 3 times, in sum 9x500sec. I was surprised that this was enough!
