If we mark the circumference of the earth we can see what was hiding behind it.

This image highlights the Aurora visible on the North and South limb of the planet. Also the zodiacal light is visible. The planet Venus is the brightest starlike object in the top left.

An annotated version of the image, pointing out a few interesting features.

The Earth as seen from the Artemis 2 mission. Because the night side is lit by the full moon the city lights are visible too. We see the north of Africa and Spain. On the left we can barely make out the American continent as it is quite cloudy there.

The reprocessed image, rotated to a world view that I am more accustomed with 😅

I downloaded the Hello World image and after some tweaks placed it in it’s starry context on a Stellarium screenshot.

Awesome shot by Reid Wiseman from the Orion spacecraft on its way to the Moon

I was on that nebula too last week. Didn't like the outcome yet... so it is still in the processing phase.

38x 300s
EdgeHD 9.25" at f/7 (1733mm) with the ASI294MC Pro camera and an L-eXtreme filter (Ha / OIII 3nm).

Stacked and processed in Siril, separately extracting Ha and OIII from the raw data

The Monkey Head Nebula (NGC 2174) in HOO 🐒✨

It has been soo long since I shared an #astrophoto on this platform. Still WIP, but I think it is coming along nicely.

Used: Siril, Sycon Starless, GraXpert denoise and deconv and a bit of Photoshop.

Shot in two panels with my Celestron EdgeHD 9.25"

VDB 63, VDB 62, Boogie Man Nebula, HH 113 and HH 122 - astrophotography by schoenmaker I don't know whether it is my editing skills or just a wrong balance of subs, but this object proved to be quite a challenge to edit to this result. I hoped that a massive amount of luminance data wou...

Finally did some #astrophotography again. The Boogey Man Nebula. Quite a difficult target to get it to show itself.

Astrofotografie voor beginners Astrofotografie is een vorm van fotografie waarbij men zich richt op het fotograferen van objecten aan de sterrenhemel. Voorbeelden hiervan zijn foto’s van de Melkweg, sterrenbeelden, de maan, planete...

Fotografie is hot inderdaad. Voor wie wat Noord-Oostelijk in Nederland zit en ook kennis wil maken met #astrofotografie kan terecht bij de Cosmos Sterrenwacht in Twente. sterrenwachtcosmos.nl/astrofotogra...

This is such an insightful post every year. Thanks @cbassa.bsky.social! My screenshot of the zoomable version also shows how I spent Christmas this year. Thanks to my automated setup I was able to combine spending time at family with doing #astrophotography in my garden at home ;-)

Witch head nebula in LRGB

Zoomed in version of the Witch Head which shows a remnant of red green and blue streaks, where geostationary satellites moved through the frame

The problem (I feel) with my edit is that I still have too few subs to properly get rid of satellite trails. Same issue with an image I shot of the Witch Head Nebula. The Orion area is a pain due to the geostationary satellites all passing by continuously.

I always feel the same with that object. This is my last attempt on it. 3 nights (24th till 26th of december); 85 x 180s with a 294MC Pro on the EdgeHD 9.25" at f/7 (1733mm). Also Bortle 6/7.

It is these kinds of images that probably show my lack of editing skills. #astrophotography

It continues to impress me, those landing rockets. New Glenn reminds me - even more than Falcon or Starship - of the Thunderbirds.

Goedemorgen. Het eerste wat ik dacht te zien was een telescoop met een automatische flatpanel... Hobby-deformatie ;-)

Mounting a reducer on the EdgeHD 9.25" together with an ZWO EAF and Celestron OAG - using a hacksaw

Hi there. A bit of #astrophotography madness for you. Did you know that mounting a reducer on an @celestronuniverse.bsky.social #EdgeHD925 can be a challenge? When there is a #ZWO #EAF mounted too, you need to reduce the bracket as well. #hacksaw

In the photo it is about at it’s highest 🫣 11.3° according to my app.

That looks great! I have so far had two attempts at this target, but I am not satisfied yet. Need to find a spot where there is no light dome in that exact direction.

But now with the reducer it fits and I got a nice #firstlight

Mounting the reducer required the use of a hacksaw 😳

I’ll make a video of the footage I shot of that process.

Last week I attempted WR134 in Cygnus. It couldn’t fit in my FOV without doing mosaics at f/10. An initial test stack got me to this. 4 panels as is painfully clear from all challenges I got to endure.

Should’ve done this much earlier. I got a 9.25” @celestronuniverse.bsky.social #EdgeHD in july 2023. But it wasn’t until last night that I mounted the 0.7x reducer.

Working on a YouTube video about #astrophotography at a 5000 year old burial site in the Netherlands.

Will take some time still as I am also learning #davinciresolve for this vid.
