The Monkey Head Nebula (NGC 2174) in HOO πŸ’βœ¨

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.

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.

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 🫣 11.3Β° 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.

This movie shows the bubbling surface of a distant star, as captured with unprecedented clarity by the ALMA observatory.

R Doradus is a huge star. Each of these bubbles is 50-75 times the diameter of our entire Sun! πŸ§ͺπŸ”­

You sir, are a machine. I still have to make my 100th post since moving from the Blue Bird to this platform. I guess my content of Astrophotography isn't as interesting as yours. ;-) Or I post too few images.

I was at the #ATT in Essen, Germany. Europe's biggest expo, according to themselves.

I made a video touring the event. Were you there too? Did I miss anything? Feel free to leave me suggestions for next years edition on May 9th 2026

My M51 project obsessive data mongering is done (for now). Curiously it was only the 4th time I was imaging this very well-known target.

As I have only been sharing the crop, I thought to also show the full field of view.

Need to play with my data a bit more, but I am thoroughly impressed with the new @siril.org and its ability to stack and stitch mosaics.

Editing my data of M51, I tried pushing it to the extremes. I still think it is awesome to see so much resemblance between my @celestronuniverse.bsky.social backyard image and that of @stsci.edu #HST Hubble Space Telescope.
