Interest & practice

I photograph the sky and work with astronomical images in research. These Milky Way fields, meteors and Tiangong photographs are another side of that interest.

The Summer Triangle

The Milky Way field, followed by a meteor composite of the same part of the sky.

Meteors in the field

A darker, softer sky gives the fine trails more room to stand out.

Toward the radiant

Another star field, and a composite bringing together trails from multiple exposures.

Tiangong passage

A track across the star field, with the intervals between exposures still visible.

These photographs have artistic treatments. The meteor composites combine multiple exposures; a few trail identities remain unconfirmed.

From the camera to HST images

For the collaborative study of SBS 0335-052 E, I processed archival HST images and made the color composite. The full image and the figure from the paper are both available below.
