Description

I want to image M57 for a long time now, but I dont have the focal lenth. So this is just a quick Test with the 8" Newton and the APM 2,7x Barlow. The camera is not modified, because my two 600Da were already busy. With my old EQ5 and no guiding, it turned out surprisingly good.
With the barlow I'm at f12 and I hope, if I make the real thing soon, that I can get enough data for a nice Ha Halo.🙂
