Description

M94, a pretty but demanding target. Compared to the core , the ring is pretty faint.
After my first attempt with the Eos, this is my second try. I think , it still could use a few hours or a proper dark site.

This great galaxy cries for a great load of photons.

"The galaxy is a most intriguing sight ... , because with time, it seems to peer right back at you, like a hypnotic eye" ~ James O'Meara
