Hello all. Decided to pull out the 8″ Dobson after it was in storage for 12 years. I’ve probably used it more in the last 3 nights than I have in the 15 years that I’ve had it. Really enjoy observing now. I got a new eye piece, 7mm and noticed an arch looking thing on the moon. I tried to snap some pics with my phone. It was on the bottom right of the moon at the time of taking. Taken from southern ca.
