Been a good dark of the moon (time of the month with no moon in the sky) with the
astronomy binocular. Even got a glimpse of some southern constellation objects through all the light pollution and summer haze. Had a couple nights of excellent sky transparency and was able to add M22 to my urban
globular cluster list, though neighboring M4 was just too darn dim to see. Where I have lived in the past, I used to use M4 as an indicator of observing conditions. Since moving to Chicago, I have never seen it, even with my excellent
Nikon Astroluxe 10x70. Guess that says it all about astronomy in the big city, up here in the north.
