Clear sky, balmy weather and worries for an injured Trumpeter Swan seen earlier provoked a need to burn off some nervous energy. Moonshot is 50% crop, or 2464 x 1632 pixels @ 300 dpi, from the sensor. Then resized for forum standards.
Shot with the O-GPS-1 on a K5 and an old PK"A" 400mm F/5.6 achromat plus a PK"A" 1.4xL TC. Exposure is 60 seconds @ F/20 at 80 iso. GPS unit, once calibrated, shifts the sensor for up to about 5 minutes, to accommodate the earths rotation. First time I've played around with astro tracking, normally use the GPS data embedded in pics of banded swans, for the folks that monitor them. Perhaps try a 500mm with a 2x TC, when contrast is better as waning phase begins.
