Mars on 19 October 2020, taken with Celestron 11 EdgeHD @f/25 at 23:49 CEST. The prominent structure near the center of the disk is Valles Marineris, a system of giant canyons about 4,000 kilometers in total length. Each of the canyons easily dwarfs the Grand Canyon. North is up.

NGC 4631

NGC 4631 is also known as „whale galaxy“. The full picture also shows its neighbor, the „hockey stick galaxy“. Taken in spring 2020 with the Starfire AP155.

M 100

M 100

M 100 is one of the most prominent face-on spiral galaxies in the early summer´s skies. Deep pictures not only show the magnificent spiral but also reveal a subtle tidal stream between M 100 and its satellite to the north. Our picture also shows plenty of faint background galaxies in the surrounding. Make sure you also watch the full resolution.

NGC 2023/2024, IC434, vdB 50/51

The horsehead nebula (IC 434) is probably among the most famous deep-sky objects. Visible to the aided eye only in the biggest telescopes, it is rather easy to photograph. This picture also shows some famous nebulae in vicinity: NGC 2023 and NGC 2024, aka the „flame nebula“ for obvious reasons.

NGC 2261 (Hubble’s Variable)

NGC 2261 (also called Hubble’s Variable Nebula) is a reflection nebula located in the constellation Monoceros. The nebula is illuminated by the giant B0 star R Monocerotis (R Mon). This star cannot be seen directly but is hidden in the nebula.

vdB 137 / IC 5076

This galactic nebula  is listed both in the catalogue of van den Bergh (vdB) as number 137 and in the IC catalogue as object 5076. The blue color indicates this is reflected starlight rather than luminescence of the interstellar matter itself (which would be red). To the East (right hand) we see „bays“ of interstellar dust projected against the bright nebula. VdB 137 is located closely north of the North America Nebula NGC 7000 but is only rarely imaged.

NGC 4559


Coma Berenices is home to numerous impressive galaxies. Nonetheless, given the vicinity to some of the most prominent supergalaxies like M87, M100 and friends, NGC 4559 might not get the attention it deserves.
