I like to use various observatories to take photos of the night sky.

2024 Solar Eclipse, Baltimore, 90% Coverage

I observed the 2024 solar eclipse at JHU, Baltimore on April 8, 2024. The maximum coverage is approximately 90%. The event is captured with my personal camera Nikon D7100, equipped with a 140mm lens and a UV filter.

M51

We observed M51, the whirlpool galaxy, with the 3.5m Apache Point Observatory on Mar.12, 2024. The overwhelming reddish color are from h-alpha filter, corresponds to booming star formation✨! The image consists of two 50-second exposures through the SDSS g’ filter, three 50-second exposures through the i' filter, and three 100-second exposures in an Halpha filter. I observed with Gavin Wang (JHU), Ryan Lessing (JHU), and Gautham Pallathadka (JHU) as a part of the Observational Astronomy class. I did the post-processing with Python and Adobe Lightroom!

NGC2403

We observed NGC2403, a spiral galaxy at redshift 0.00044, with the 3.5m Apache Point Observatory on Mar.13, 2024. The image consists of three 30-second exposures through the SDSS g’ filter, three 50-second exposures through the u' filter, and three 100-second exposures in an Halpha filter. I observed with Gavin Wang (JHU), Ryan Lessing (JHU), and Gautham Pallathadka (JHU) as a part of the Observational Astronomy class. I did the post-processing with Siril, Python, and Adobe Lightroom!

Orion

We observed the great Orion nebula on Nov.4, 2023 with the 20-inch Morris W. Offit Telescope at JHU. The image consists of 90-minutes exposure from a DSLR. I observed with Gavin Wang (JHU) and Alexander You. I did the post-processing with Siril and Adobe Lightroom!
