„Lift up your eyes to heaven and see. Who has created these things?
It is the One who brings out their army by number; He calls them all by name.
Because of his vast dynamic energy and his awe-inspiring power, Not one of them is missing (…)”

Middle Eastern poem about the stars, 8th century BCE

Our recent pictures

Heart Nebula

IC1805 / Melotte 15 / Collinder 26

This is the Heart Nebula (7,500 light-years away) and you see over 20,000 stars in this image. Some of the stars in this image are ~50x Sol masses but most are a lot smaller.

C/2022 E3 (ZTF)

Comet C/2022 E3 (ZTF)

Pretty comet almost at its closest approach to Earth, about 42 million km away. The weather was unforgiving, -10°C with just a brief window of opportunity. We can always capture it next time it returns, in roughly 50.000 years…

Double Cluster

h Persei & χ Persei / Caldwell 14 / NGC 869 & 884

Two young star clusters about 7,500 light years from us. They reside in the Perseus arm of the Milky Way, while we are living in the Orion arm. So looking at the Double cluster you are looking through our local spiral arm into the neighbouring arm outward from the galactic center. Interestingly they are speeding towards us at 140,000 km/h.

M45 / Seven Sisters / Kiʹmah

Kiʹmah is possibly a reference to Pleiades in Amos 5:8:
The One who made the Kiʹmah constellation and the Keʹsil constellation,
The One who turns deep shadow into morning,
The One who makes day as dark as night,
The One who summons the waters of the sea
To pour them out on the surface of the earth
—Jehovah is his name."

Sadr Region

Pretty dark nebulae in front of hydrogen clouds

The red/orange parts of the image are made up of hydrogen and sulphur, the bluish parts are oxygen. The black parts are dark nebulae or absorption nebulae which block the light of the stars behind them. You can see such dark clouds with the naked eye as dark patches against the brighter background of the Milky Way!

M33 / NGC 598

Triangulum is the smallest spiral galaxy in the Local Group (us, Andromeda, the Magellanic Clouds and a few more neighbours). It is thought to be satellite galaxy of Andromeda as they are moving towards us together. In 4 billion years all three galaxies might merge into one big elliptical galaxy!

How do we take astrophotos?

What kind of equipment is needed to take these pictures

People keep asking us if these pictures are made by us. They are. Really. This is the equipment we use.

Assorted throwaway pancakes

More often than not astrophotos don’t come out the way you planned them to. There are about 200 steps involved in taking a picture, and they all have to be right. Also, often we need to experiment, finetune equipment or the sky is not good enough for long enough to finish a project. These are some examples of failures and experiments.
