4 h 30 m

Full APS-C frame. Many galaxies are visible around. First test of the Player one Anti-Halo 2" UV IR-CUT Filter. Works perfectly — no halos (without it, halos covered half the frame). First test of auto meridian flip in NINA done without losing time (not 10 minutes for the flip). Worked perfectly. Capture: NINA, phd2Processing: PixInsight, GraXpert (for bge)
