Description

First astrophoto I take with my improvised "apo eco": a 200mm canon lens and a 1.4x extender = 280mm focal length.

The seeing was terrible and at the end of the dawn and only managed to catch less than 3 hours. I still don't know if the problem is with the extender, with the excess of lenses or with the sky itself. The spikes on the main stars were too big and the others had an almost incorrigible halo. Will test again when the weather improves.
