How can I be one with the universe when we don't know what 96% of it is.

Ahh - the old 'coathanger'. It is always a marker for summer observation sessions. It is visible to the naked eye in reasonably good skies, although at that scale it looks like a little fuzzy line rather than a 'coathanger'.
I use an 11" Celestron SCT (CPC 1100) on an equatorial wedge, housed in a 2.2m Pulsar observatory. I use a ZWO ASI1600MC and Canon 500D for imaging.

I like the use of the Coathanger as a calibration tool for photometry devices as its stars cover a relatively narrow range of magnitudes, hence why Brocci identified it as a valuable cluster
