Cambria County, Pennsylvania - Comet NEOWISE by drone
DJI Mavic Air 2. Single 8 s exposure, ISO 400,, f/2.8. Cropped and heavy noise reduction applied in Lightroom. - 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. - Moon and Jupiter
- Extreme corona
August 2017 total solar eclipse Lake Keowee, South Carolina, USA This is from my longest single exposure. I pushed this one as far as I could, to the point of excessive noise and artifacts, to reveal the extended coronal structure and earthshine on the moon. - Sudden Brilliance

August 2017 total solar eclipse Lake Keowee, South Carolina, USA With this version of my second-longest exposure, I've tried to balance the structure in the corona with good detail in the large prominence. - Total lunar eclipse, January 2019
Mahaulepu beach, Kauai - ISS Lunar Transit
Composite of 13 exposures showing a lunar transit of the International Space Station. Photographed from Croyle Township, Cambria County, Pennsylvania, USA at 2016-05-28 08:45:48 UT. The duration of the transit was 1.3 seconds. The distance to the ISS was approximately 715 km and its angular size was about 39 arcsec. Planning for the transit was done using CalSky.com. Pentax K-5 II, Pentax DA* 300mm f/4, Tamron 1.4x teleconverter. Exposures were 1/2000 second with the lens set to f/4 (for an f/5.6 effective aperture with the teleconverter). - Delphinus 20140826
First night using the Astrotracer functionality of the Pentax O-GPS1. 4x120 seconds on a fixed tripod. Stacked with DeepSkyStacker. - Moon, Venus, and Mars
I took this out my open bedroom window, so the seeing was trash. - Passing Cloud

Composite of a flash-illuminated foreground shot and 366x20s sky exposures. - Partially eclipsed moonrise over Kawelikoa Point, Kauai
- 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. - Eclipse composite
