mag limit test (Union)

Did a naked eye mag limit test in Gemini. Sketched the view.



Pollux is the bright star on the top-left; Castor is top-right. The star at the arrowhead is either b or 63 Gem, both of which are around mag 5.0. The star between κ (kappa) Gem at the bottom-left and Pollux is c Gem, mag 5.3!

I also noted the conditions: 51%; 5.3°C.
