50mm refractor f/4 and ZWO ASI178MC Camera


This is a 7 image gif covering 1 hour 36 minutes in the life of Comet C/2017 T2 (PANSTARRS). Each image is 300 seconds (15x20s) and the images are about 10 minutes apart. The field of view is 1.9 by 1.3 degrees. The images were captured with a 50mm refractor f/4 and a ZWO ASI178MC camera. 2017 T2 reached perihelion in its 217,924 year orbit on May 4 reaching magnitude 8 and is now moving away from the Sun and Earth. When these images were taken the comet was about magnitude 10, 181 million miles from Earth and moving across our sky at 0.8 degrees per day.
