NGC 936 – VdS Remote Hakos

As a member of the VdS Remote Observatory Group, I again had the opportunity in 2024 to make use of the excellent facilities at Hakos, Namibia, to image the barred lenticular galaxy NGC 936. The superb southern sky conditions and the professional remote setup provided excellent resolution and depth, ideal for capturing the subtle structural features of this intriguing system.

This galaxy is located in the constellation Cetus at a distance of roughly 60 million light-years. It is classified as a barred lenticular galaxy (SB0) and is considered a prototypical example of a system in transition between spiral and elliptical morphology. The galaxy exhibits a strong central bar embedded in a smooth, lens-shaped stellar disk, but lacks prominent spiral arms.

Deep imaging reveals a bright, well-defined bar structure surrounded by a diffuse outer envelope. As a lenticular galaxy, NGC 936 contains relatively little interstellar gas compared to typical spirals, and star formation activity is correspondingly low. The observation under Namibia’s pristine skies allowed the faint outer halo and subtle brightness gradients within the disk to be recorded with high fidelity, highlighting the elegant simplicity of this early-type barred galaxy.

All data calibration, registration, and final processing were performed in PixInsight.
