Mammoth Cave National Park to host astrophotography workshop

MAMMOTH CAVE, Ky. – Mammoth Cave National Park is hosting an astrophotography workshop on Friday, Sept. 19.

The park says activities will begin with a night sky evening program at 6:30 p.m. in the outdoor amphitheater before moving to the bus loop behind the visitor center at 7:30 p.m.

At that location, participants will set up their astrophotography equipment.

Park officials say park rangers experienced in astrophotography will assist photographers who may be new to night sky photography techniques as well as those who are well versed in how to gather images of objects in space.

The workshop will focus on gathering photos of one of the hardest night sky objects to capture – a section of Integrated Flux Nebula, known as the Polaris Flare.

Staff recommend participants plan for at least two hours of data gathering to get good images. Rangers will be on site until 10 p.m., however, participants may stay later to collect more images after the event ends.

Photography equipment will not be provided by the park. Photographers should bring a sturdy tripod, digital single lens reflex or similar cameras with exchangeable lenses, extra camera batteries, a telephoto lens and an intervalometer or way to achieve remote shutter control. Telephoto lenses should be between 50 millimeters and 400 millimeters, but 135 is the best option to capture great night sky images.

The lower the focal ratio, such as between f2 and f4, the better for night sky photography. A computer will be needed for editing the captured data but will not be required during the event.

It is also recommended for participants to bring a lens hood to dampen ambient light, handwarmers and rubber bands to prevent your lens from fogging up, a camp chair and a jacket or blanket to keep comfortable in the cooler nighttime temperatures.

All activities are weather dependent and may be canceled in the event of hazardous weather.
