Description

M57 Ring nebula

Here is my first picture with my new camera! I bought the camera used, which made it affordable for me. It definitely is an upgrade of my modified Nikon d5300 
Especially having the option to bin my images at 2032mm focal length is a real pleasure! The quantum effiency is much higher and the 16bit range is amazing! After stacking some Ha images I could already see the outer shell of M57, which haven't been possible so far! 

To sum it up, I am really happy with the Atik 490ex mono! At first I had a bit of trouble shooting because the cooler was causing vibrations. After replacing it with a new one, they disappeared.

Here is an image with the old cooler, you can clearly see that the passing satellite has some "problems"! 

The exposure time could be a bit longer to reduce the readout noise and I will definitely add some more in the future.
