Thanks Kevin. All in all I would say, I was a bit untalented. As I put out the cam I saw the first mistake. The 300mm lens was mounted on the D80, not on the D7200. With the noise level of the D80 and ISO800 the result was not amazing ... and 2s exposure time was to long. I should better go with 1s ... but not at ISO 800 ... . I will do it better for January :-)

Greetings, David

I know such situations too well. Everything is prepared or already running and then a small mistake paralyzes everything. One day I forgot my Bathinov mask in front of the telescope :-D

I also hope to can make some things better in January :-)
