Comet Tsuchinshan-ATLAS C/2023 A3 October 2, 2024 at 11:16:16 UT
Photograph of Comet Tsuchinshan-ATLAS taken with a ZWO ASI178 color CMOS camera, and Pentax 28mm f/3.5 lens mounted on a barn door tracker. This image consists of a single 10 second exposure captured with ASIImage. This image was taken in the parking lot of the Baker Wetlands Discovery Center in Lawrence, KS.
]Comet Tsuchinshan-ATLAS C/2023 A3 September 29, 2024 at 11:11:25 UT
Photograph of Comet Tsuchinshan-ATLAS taken with a ZWO ASI178 color CMOS camera, and Pentax 28mm f/3.5 lens mounted on a barn door tracker. This image consists of a single 5 second exposure captured with ASIImage. This image was taken in the parking lot of the Baker Wetlands Discovery Center in Lawrence, KS.
Comet NEOWISE C/2020 F3 July 21, 2020
Unguided photograph with a ZWO ASI178 color CMOS camera attached to an Olympus 35 mm f/2.8 lens. This image consists of 40 ten second exposure images stacked with ASILive. This image was taken a few miles north of Lone Star, KS from the side of a county road.
Comet NEOWISE C/2020 F3 July 18, 2020
Unguided photograph with a ZWO ASI178 color CMOS camera attached to an Olympus 35 mm f/2.8 lens. This image consists of 11 two second exposure images stacked with Registax. This image was taken a few miles south and west of Lawrence, KS from above the Clinton Lake Dam. The photograph was taken just before clouds obscured the comet and before it got dark enough to capture the ion tail.
Comet NEOWISE C/2020 F3 July 15, 2020
Unguided photograph with a ZWO ASI178 color CMOS camera attached to an Olympus 35 mm f/2.8 lens. This image consists of 25 two second exposure images stacked with Registax. This image was taken a few miles south and west of Lawrence, KS from above the Clinton Lake Dam. The photograph was shot through cirrus clouds but you can still see the ion tail.
Comet NEOWISE C/2020 F3 July 15, 2020
Unguided photograph with a ZWO ASI178 color CMOS camera attached to an Olympus 35 mm f/2.8 lens. This image consists of 23 two second exposure images stacked with Registax. This image was taken a few miles south and west of Lawrence, KS from above the Clinton Lake Dam. The photograph was shot through cirrus clouds.
Comet NEOWISE C/2020 F3 July 13, 2020
Unguided photograph with a ZWO ASI178 color CMOS camera attached to an Olympus 35 mm f/2.8 lens. This image consists of 21 two second exposure images stacked with Registax. This image was taken a few miles south and west of Lawrence, KS from above the Clinton Lake Dam.
Comet NEOWISE C/2020 F3 July 13, 2020
Unguided photograph with a ZWO ASI178 color CMOS camera attached to an Olympus 35 mm f/2.8 lens. This image is a single 2 second exposure. This image was taken a few miles south and west of Lawrence, KS from above the Clinton Lake Dam. The shims that I added to the camera adapter solved the issue with the out of focus stars.
Comet NEOWISE C/2020 F3 July 12, 2020
Unguided photograph with a ZWO ASI178 color CMOS camera attached to an Olympus 50 mm f/1.4 lens. 2 second exposure. This image was taken a few miles east of Lawrence, KS from the side of a county road. The adapter that I used to connect the vintage Olympus lens to the CMOS camera is one that I made many years ago but never used it until now. I discovered that the lens' optical axis was not perpendicular to the camera focal plane which resulted in star images that would not come to a complete focus. I had to use a lot of deconvolution to get the star images so that they were round, resulting in a lot of processing artifacts. I added some shims to the adapter and I will try taking some more images tomorrow morning if it remains clear.
Comet Pan-STARRS March 13, 2013
Unguided photographed with an Olympus OM1 mounted on a tripod, an Olympus 500mm telephoto lens, and Ilford Delta 3200 ASA B&W film. Approximately a 5 second exposure taken from the Clinton Lake Reservoir south of Lawrence, KS. The film was developed at 1600 ASA.
Comet 8P/Tuttle January 6, 2008
One minute color image taken with an seven inch AstroPhysics AP180 refractor and SBIG STL-2000C CCD camera.
Comet 17P/Holmes January 6, 2008
Three minute color image taken with an eight inch AstroPhysics AP206 refractor and SBIG STL-11000 CCD camera.

Unguided photographed with an OM1 mounted piggyback on my LXD55 8" SCT.5 minute exposure on Polaroid 800 ASA film with a 135mm lens.
Comet NEAT May 16, 2004
Unguided photographed with an OM1 mounted piggyback on my LXD55 8" SCT. 5 minute exposure on Polaroid 800 ASA film with a 500mm lens.
Halley's Comet January 5, 1986
Unguided photographed with an OM1 mounted piggy back on the Washington State University 12 inch Clark Refractor. Black and white print from a color negative.
