Haven't seen a lot of posts about the Luminous Red Nova AT2025abao in M31 on here, so I thought I give it a try and 2 days ago weather cleared up just long enough to get a bit of #Astrophotography data. I was really surprised that it was visible even in single subs.

The Veil nebula in Cygnus imaged with my Samyang 135mm F2 lens. A great #Astrophotography target for Summer and early Autumn. Despite its distance of ~2500 lightyears, this supernova remnant just fit into the frame. Total exposure time about 2 hours.

Still no clear weather in sight, so here are a few more fly agaric from my local forest. #mushroom

Had a quick glimpse between the clouds on comet C/2025 A6 (Lemmon) in Canes Venatici well after sunset. Composite of around 3 minutes worth of 1 second untracked images. #Astrophotography

An other fly agaric growing in my local forest, while I'm waiting for a clear sky. #mushroom

More mushrooms from a local forest. The damp weather really helps them grow very fast.

As expected from this season, its cloudy and no stars in sight. But on the other hand mushroom season is in full swing.

The Helix Nebula or Caldwell 63 is a planertary nebula in the constellation Aquarius. When it comes to planetary nebulas, it's apparent size is extremely large and its features and structures become visible even in mid sized telescopes. Making it a very interesting #Astrophotography target.

Neptune and it's moon Triton(which might actually be a captured dwarf planet) in the early morning hours of 6th September. 10 second exposures at f27 where just enough to make Triton visible without resulting in trailing lights. #Astrophotography

Besides the planets there is of course the Moon as a bright target. I tried to utilize the full width and length of an APS-C sensor by using a 2x telecentric barlow. The cropped in images should provide full resolution of some regions. #Astrophotography

While Deep Space has to take a back seat in #Astrophotography during the current Moon phase, I'm trying to squeeze out every last bit out of my Deep Space Rig for planetary imaging. Here is Saturn through my 130mm Newton and Canon EOS 250d.

Not a typical #Astrophotography target, but I really really wanted to try and see if can at least capture a glimpse of the interstellar comet #3I/Atlas shortly after sundown and just before it vanished below the horizon. Challanging with a 130mm newton and a reg. DSLR but it might just have worked.

Supernova SN 2025rbs in the galaxy NGC7331 from yesterdays short #Astrophotography session. My personal first for a type 1a Supernova (The bright spot right next to the galactic nucleus).

The second picture of this summers #Astrophotography targets. The Trifid Nebula M20. As with M8 I didn't have nearly as much time as I wanted due to bad weather and short nights, but it is still quite a sight, even at relatively low exposure time.

Not only where the nights extremely short like every summer, the weather also didn't want to play nice for #Astrophotography this year. Which means I wont get any more time on the targets I had selected this year. But I did get a few h on the Lagoon Nebula, despite it being insanely low in the sky.

My favourite galaxy cluster for #Astrophotography by far is the Coma Cluster in the constellation Coma Berenices. It might not be as majestic as the Virgo cluster, but the sheer number of small galaxies in the FOV of a medium sized telescope is breathtaking. Imaged with my trusty Canon EOS 250d.

Prometheus fired up once again (and again) 😎🔥 Prometheus performed 4 consecutive ignitions on 20 June, a first in Europe for this type of engine. The hot-firing campaign was held on the PF20 test bench at ArianeGroup’s site in Vernon, France. Read more: www.esa.int/Enabling_Sup...

T Coronae Borealis still seems to behave.(Or misbehave depending how you view it). No obvious sign of a Nova as of an hour ago. #Astrophotography #TCrB

Every now and then, I'm going after asteroids during #Astrophotography sessions. Orange was the position of (2)Pallas in the early hours of 28th June. Green is the position in the early hours of 29th. (different cameras on my telescope, so image scale is slightly different).

Exceptional convoy! 🛻🚀 Europe's first reusable rocket stage demonstrator #Themis is all wrapped up and ready to roll from its integration hall in France to launch pad in Sweden. Bon voyage! www.esa.int/themis

Just realized that I never imaged the Eagle Nebula before. I used a regular unmodified Canon EOS 250d on my 130/650mm Newton for this little preview. Time was a bit limited since it is already getting bright outside at around 3 in the morning. #M16 #Astrophotography

We have reached the top! The protective dome of our ELT will have two giant sliding doors that will open at night to allow observations. Their structure is being installed on the dome, meaning that the ELT has reached its highest point. www.youtube.com/watch?v=JNPk... 🔭 🧪

Before the good weather for #Astrophotography is gone I wanted to revisit Messier 13 and also try something different. So i setup my 130/650mm Newton telescope with a 2x telecentric barlow lens to capture the Hercules Cluster in a bit more detail.

Weather is a bit better currently. So I was able to setup my telesope for #Astrophotography yesterday. My target for the night was NGC4236. A faint barred spiral galaxy in the M81 Group about 11 million light years from Earth. Small preview with slightly blobby stars thanks to fokus shift.

Amateur-level hardware can do science! A new paper by David Martínez-Delgado et al. shows a decade of results from an amateur/professional survey. 🧪☄️ #astrophotography The pic on the left is from DESI, the right from their survey; notice how there are no horizontal/vertical mosaicing artifacts.

Weather is beginning to look a lot like last year for #Astrophotography. But despite that, I was able to collect some data every now and then on the Rosette Nebula for a little mosaic, with my 130mm Newton. Stacked with DSS and combined with APP.

First Light with this beast! The sky was clear just long enough to grab 21 frames on the Rosette Nebula last night with the Askar SQA106. You can see the field of view through this refractor and the types of projects possible. Full Specs on the SQA106: bit.ly/41NoEci

This image of the Sun is a little different from my others as it was captured with a SHG700 spectroheliograph that “scans” across the Sun’s Ha line in one pass. To see how this image was captured see this video : youtube.com/watch?v=12i1... Thanks to MLAstro for letting me try it!

Finally got my first #Astrophotography picture this year from Mars on the 29th. Seeing was far from perfect, but good enough for a small aperture. Also found out why my Camera was unwilling to take videos in my previous attempts. Much easier and less stressfull for the camera this way.

Had the opportunity to do a bit more #Astrophotography on the 25th. It was still early so a bit brighter than i would prefer, but still got a fair bit of data for the Horsehead Nebula.

1/ ☄️ Comet C/2024 G3 (ATLAS) is gracing our skies, and we’d like to share some amazing images from ESO's Paranal Observatory in Chile! This stunning shot by our friend Yuri Beletsky, with the comet next to an Auxiliary Telescope, is today's Astronomy Picture of the Day. Congrats, Yuri! 🔭 🧪

Nah, this timeline is crazy. Holy hell...

And yet another older one from 2021. Globular cluster M22 in Sagittarius. Even though not quite as easy to view from more northern latitudes, it is quite an impressive target for #astrophotography even in challanging lighting conditions like full moon or inside cities because of its apparent size.

Sky was mostly clear for a few hours today. So I took the opportunity to get a few hours of #Astrophotography data, even though I had to change targets a few times to stay ahead of the clouds. Needs a lot more data to reduce noise and Alnitak did not behave at all.

Second is this preview of a wide angle shot of M42 and Horshead/Flame nebula imaged with a Canon EOS 600d and 135mm lens. Total integration time at this point only ~20 minutes but more is to come. I'm also considering making a larger mosaic to include the entire Barnards Loop. #Astrophotography

Frosty!

So did a bit of processing on the first data from the #astrophotography session two nights ago. First is Jupiter again, stacked and processed to get at least a few details in the cloud bands. Sadly no red spot. Should have tried again a few hours later, but hell was it cold.
