Description

A quick imaging session after work. This was imaged later in the afternoon so the seeing was not optimal, nor was the black asphalt parking lot which I use as my "observatory". Gong network showed that this active area was producing quite some movement and smaller flares but I only had time to make a single shot. 

As usual, this was imaged via Firecapture using gain of 125 and exposure time of 6.1 ms @ 8 bit. Average FPS seemed to be 162. Best 400 frames are stacked. At full size one sees that there is a bit of softness in the image which is mainly due to afternoon imaging vs. my preferred time slot in the morning.
