Constellation Cygnus hides a marvel of galactic nebulae. The Eastern Veil Nebula is part of a much larger remnant of a supernova that exploded around 8,000 years ago. This #astrophotography was created as a mosaic of two images taken with my #CelestronOrigin, each with an exposure time of one hour.

"The star that changed the size of the universe" was discovered in 1923 by Hubble on a plate taken with the 2.5m Hooker telescope. This variable Cepheid star proved that Andromeda is a far away galaxy like our own. Today, #astrophotography with my little #CelestronOrigin can show this star clearly.

The star that expanded the universe was discovered by Edwin Hubble in 1923 with a 2.5m telescope. The Cepheid star V1 gave first prove that Andromeda is a galaxy outside our milkyway. Today, this #Astrophotography with my little #CelestronOrigin clearly shows this star in the gorgeous spiral of M31.

About 8,000 years ago, a star exploded in the constellation Cygnus. Today, we can observe the faint remnants of this supernova as the "Veil Nebula". This astrophotography was composed of two 1h exposures taken with my @celestronuniverse.bsky.social‬ Origin telescope and developed in #Pixinsight.

A few thousand years ago, the star at the center of the Dumbbell Nebula (Messier 27) ejected its outer gas envelope at the end of its life, which it now illuminates from within. This #astrophotography was exposed for one hour near full moon with my #CelestronOrigin and developed in Pixinsight.

Two very different objects shine in this #astrophotography with my #CelestronOrigin. In Ring Nebula M57 in constellation Lyra, an ejected gas shell glows in the hard UV light of a 75000K hot dwarf star from 2300LY. The galaxy next to it (IC1296, 250Mio LY) is larger than our milkyway but very faint.

The Iris Nebula (NGC7023) bears its name because gas clouds reflect the bluish light of very hot neighboring stars. It is surrounded by molecular dust clouds with embedded brownish carbon compounds. This #astrophotography with my Celestron Origin was exposed for 160min and developed in Pixinsight.

Galaxy Messier 64 at a distance of 24Mio LY is also known as "Black-Eye Galaxy" because of its characteristically shaped dust band. This #astrophotography with my @celestronuniverse.bsky.social Origin telescope is based on an exposure time just under half an hour and was developed in #Pixinsight.

Galaxy M104 is also known as the “Sombrero Galaxy” because of its striking shape. With an exposure time of 140 minutes, this #astrophotography with my #Celestron #Origin shows numerous globular clusters in the galaxy's halo, structures in the dust disk and many faint galaxies in the background.

The “Whirlpool Galaxy” M51, about 24Mio LY away, is subject to strong gravitational interactions with its companion galaxy. Countless stars are torn out of both galaxies and form extensive tidal tails. This #astrophotography image was made from 2.5h of data with my #Celestron #Origin in #Pixinsight.

Time for a late winter memory of my first deep sky object which I exposed for about 30 minutes with my #Celestron #Origin. The large Orion Nebula M42, birthplace for many new stars and planets, paints a fantastic landscape in the winter evening sky, where the eye can go for a walk. #astrophotography

In Globular star cluster M3, around 500,000 stars are crowding within just 125 light years. This #astrophotography image taken with my #Celestron #Origin lets you recognize a mixture of old, red giant stars and “blue stragglers”, which were formed by mass exchange or even mergers between two stars.

Star cluster NGC2244 formed only a few million years ago from the gas of the Rosette Nebula, which it now stimulates to glow from within with its radiation. 30min exposure with my #Celestron #Origin reveal a variety of nebula knots from which stars are still forming today. #astrophotography

In the night of 10 to 11 April, asteroid (8) Flora passed over galaxy NGC 3628 (the ‘Hamburger Galaxy’), part of the Leo triplet. During the exposure of just over an hour with my #Celestron #Origin, the asteroid drew a small streak across the long axis of the galaxy. #astrophotography

Yesterday's result of approx. 1h data with my #Celestron #Origin: the Flame Star Nebula IC405. Conditions were very bad for #astrophotography: the misty sky in my mid-town garden was bright from the moon and IC405 was not high above the horizon. The #Origin continues to surprise me, though!

Leo-1 is the most distant companion of the Milky Way at approx. 800,000LY. It resides only 12 arcminutes north of Regulus, which usually “drowns” the galaxy in its scattered light. Here, 100min worth of 10s subs from my #Celestron #Origin where stacked with a limiting magnitude of approx. 19mag.

Just a little more than 100km from you we had a lovely day under blue skies with >100 guests at the Peterberg observatory (+ >40.000 clicks on our live stream). 🤷🏻‍♂️

Still improving my abilities to make visible color and structure over all intensity regimes in #Astrophotography. Here a newly processed #Pixinsight version of 5h hours data from the #Seestar S50 of my club buddy Michael Hübgen. Note how color and structure go till the center of M42, the trapezium.
March 17, 2025 at 6:42 PM
I hate posts like “Here my few s of data from yesterday without processing directly from camera”. Peers: dare to collect data and use software to make the best out of it! Here appr 2h of #Seestar S50 data from my astronomy club buddy Stefan Schorr, processed in #Pixinsight by me. #Astrophotography

Do not give up hope, Markus, the information is in your data and we will bring it out by working on the stretching process! Remember this very early version of just one of your tiles? The potential of the Celestron Origin ist just gorgeous!

I agree that the capabilities of the software are beyond imagination (weird?). However, it displays only details that you would expect from its optic's data, both, when shooting freehand (20-30 arc sec) and on the scope (~5 arc sec). To me, the math is more convincing than a "Samsung conspiration".
