After my last experiment with my old 100 Euro ST80 400mm Refractor I got myself a new toy: A 480mm APO Refractor with extra Flattener.
Below is the first image I did. Because of incoming clouds I just had only time for 2 quick 45 sec snaps of M15. But both the colors and shapes of the stars are so much better with this refractor.
Looking forward to some truly dark nights on Hinterhorn Alm for some long exposure rich fields.
