Description

Finally got around to processing my Leo trio subs. Taken over 4 separate visits to Pinnacles National Park with some high clouds on 2 of the nights.

The three galaxies hold a special memory for me—being one of the first galaxies I observed through my Dob when I got into the hobby. I re-lived some of the thrill of being able to see multiple colossal objects several tens of millions of light years away in the same FOV, through imaging and processing the galaxy triplet.

A little disappointed with the noise even after 5 hours of integration—I expected to see more of the tidal tail of the 'hamburger'.
