Since weeks bad weather... but yesterday I had luck :-)

So, again M45 Pleiades (how wonderful to focus with the Bahtinov mask because of the bright stars...), this time at f/5.6. Therefore no spikes. It looks more realistic to me with the round stars and no spikes...

Drizzled 2x and resampled to original resolution.
