This is a second image I was able to capture during my quick first light attempt. Clearly the diffraction spikes are off causing the stars to look strange. The wires need to be oriented 90 degrees from each other but I was I such a hurry to get something imaged I just ran with that I had . And now the forecast is a week of rain, followed by a full moon. Oh the curse of new equipment is alive and well here in Pennsylvania.
