First galaxy of the season - NGC2903


Recommended Posts

And with the galaxy season upon us, here is my first for this year.

Because both of my cameras were out for repairs, this galaxy was shot with a friend's ASI183M who was very kind to lend it to me so won't be out of action.

A bit more luminance with no moon would've helped a bit but I'm happy with what I got so far.
