I am a software engineer, working with , ( ). In my free time I do and . I will be posting the photos I take with my telesope here.

I care about , , , and

Just cleaned all my for my mono chrome and installed my new O-III filter.

New coming soon, busy setting everything up and tinkering with the .

Hello everybody, trying out the new groups :D

I am an astrophotographer, taking photos of deep space with a .

Attached one of my latest photos (the cygnus wall, or NGC7000)

Finally getting my O-III narrow band filter. Only took almost 1 year 😆

Baader seems unable to ship the O-III filter (ordered it back in last year april). Getting an Astronomik O-III filter now instead.

Since I already have a Baader Ha and a Baader S-II filter the new O-III filter won't b e parfocal, meaning I will have to measure focus offsets.

Which narrow band filters do you prefer?

A with my "old" Schmidt-Cassagrain (Celestron C8) and the "new" Ritchey-Chretien "TS Optics RC 8")
The new RC telescope is a lot sharper and a lot more detail can be seen, given the same exposure time.

The nebula in the photo is the crescent nebula (or NGC 6888)

Visible in this image is also the Grand Valley on Mars, which was used to be believed to be an ocean of water in the earlier days of astronomy.

The photo was shot at ~6100mm focal length, with a Celestron C8 SCT and a 3x barlow lense, using an ASI 224mc as

Imaging planets isn't as most believe. This photo is actually the result of 5000 photos being combined into one.
For this a technique called "lucky imaging" is used.
At these magnification levels seeing (turbulence, ...) causes Mars to just look like a red blob. The software can then take the best of those 5000 photos to reconstruct the details lost because of the atmosphere.

Currently busy editing my newest photo (of the M74).

This is the combined stack of 105x60s exposures with the L (= Luminance) filter, basically a monochrome photograph used to enhanced contrast and detail in RGB photos.

Currently imaging the M74 and just had a pass through the photo. The galaxy is the fuzzy dot in the center of the image, the satellite is visible as straight line at the top of the image.

This kind of thing is going to happen a lot more often with -musk -link

-pollution -sky

While the weather is bad and I can't take new photos: An old from 2018

The two galaxies M81 and M82 are located about 12 million light years away.

M81 on the right is a grand-design about half the size of the milky-way.

M82 on the right is a burst galaxy, holding lots of hydrogen (visible as red in the center) and having a lot of new stars being born.

This is what is called a

Many many stars that are being pulled towards its center. These are "smaller" structures that orbit around our galaxy, the .
To this day these star clusters are a big mystery. They seem to be composed of mostly ancient stars. Why are they forming this sphere outside of the galaxy?

4x600s exposures

NGC7331 with Stephans Quintet

A I took in 2017. On the top right is the big NGC7331. Whereas in the lower is the Stephans Quintet (4 Galaxies being so close, that they interact with each other). The interaction can clearly be seen by the distorted spiral arms of a few galaxies. Some of the galaxies in this photo are located over 300 million light years away!

Due to bad weather outside, setting up the telescope in the cellar to test out things and optimize my settings. Finally got meridian flip to properly work together with the mount slew settings :)

Next imaging session going to work a lot smoother.

An older that is the result of a collaboration with a user on Discord.

The M63 or sunflower galaxy is one of our neighbours located ~30 million light years away. Having a in its core that has the mass of over 850 million times more than our sun.

Totaling around 10 hours of total exposure time using DSLR and a Moravian G2 8300

NGC6888 The Crescent in LRGB

Second with my new setup. Got the spacing between the focal reducer and the sensor close to its optimum.

The Crescent nebula is matther thats being formed into a cloud shape from stellar winds. Wolf-Reyet stars produce magnetic winds in space, pushing / moving ionised gases like hydrogen, oxygen, etc...

a bit over 3 hours of total time

The first taken with the new setup.

This is a small part of the North America (or NGC7000) called the Cygnus Wall.

Taken with a camera using a Ha (hydrogen alpha) and RGB filters resulting in a HaRGB color image (Luminance = Ha, RGB). So it's basically a true color photo!

The nebula is one of the most dense star forming regions of our

Successfully tested my new setup yesterday, Running on a controlling everything

Can't wait to take some awesome photos with this new setup!

Been working on my setup, got all the mounted on top of my GSO RC 8" telescope.

Everything is controll with and a 4 now that runs off a 48Ah 12V lithium battery.

Cant wait to get the first photos with my new setup!
