- Eclipse composite
August 2017 total solar eclipse Lake Keowee, South Carolina, USA - Orion's Sword 20131227
Playing around with astrophotography. This is a stack of about 580 dark-subtracted exposures from a stationary mount, 0.3 seconds each, ISO 1600, Pentax DA* 300mm f/4 wide open. Trailing of stars is still apparent. I'm impressed by how much detail even a single exposure contains. It would be nice to get the O-GPS1 accessory to extend the individual exposure time to several seconds without star trails. - Comet 46P/Wirtanen & Pleiades
Pentax K-3 II with Astrotracer, Tamron 70-200mm f/2.8 at 70mm, f/4, Hoya red intensifier filter to reduce light pollution, 25 x 10 seconds. I was not able to see the comet by eye with binoculars. The moon was near the field of view, to the right.
