Astronomy & Astronomical Imaging

Exploring the sky through imaging, computation and observation.

Astronomy, astrophotography, observational projects, astronomical imaging and scientific software by Hossein Zarei Oshtolagh.

Astronomy has been part of my scientific life for many years.

My interests span observational astronomy, astrophotography, astronomical image processing, telescope and camera instrumentation and computational methods for astronomical imaging.

My academic background began in physics and astronomy, including work at Amirkabir University of Technology (Tehran Polytechnic). I currently work primarily in computational microscopy and imaging, while continuing my interest in observational and computational astronomy in Jena, Germany.

I am particularly interested in problems where optics, image formation, numerical methods and scientific computing meet.

High-resolution observations of the Moon using short exposures or lucky imaging.

Solar observation

Solar Imaging

Observations of the Sun, including high-resolution imaging of solar structure and H-alpha observations.

Astronomical image of Orion

Deep-sky Imaging

Imaging deep-sky objects.

Astronomy through algorithms.

Software and computational experiments for extracting, reconstructing and interpreting astronomical information from images.

PlateSolving.jl ↗

A Julia package for astronomical plate solving, identifying sky coordinates and image geometry from detected stellar sources.

Lucky Imaging

High-resolution reconstruction from short-exposure image sequences through frame selection, registration and computational combination.

Speckle Interferometry

Computational analysis of short-exposure stellar observations using Fourier-domain methods for investigating high-resolution stellar structure.

Differential Image Motion Monitor

Experimental work toward measuring atmospheric seeing through differential stellar image motion.

Volkssternwarte Urania Jena e.V.

Volkssternwarte Urania Jena

I am a member of the Volkssternwarte Urania Jena e.V. in Jena, Germany.

Through the observatory, I continue my involvement in observational astronomy and astronomical imaging alongside my scientific work in computational imaging and microscopy.
