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

@dylanodonnell.bsky.social I was in London for work and found something that made me think of you

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 youtu.be/5hUqAVTlH88

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. youtu.be/i9SymknulPk

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! 🧪🔭 www.almaobservatory.org/en/press-rel...

How is your #Dutch? And you like #astronomy? Know @sterrenstofnieuws.bsky.social already? In their latest podcast (48) they suggest the #astrophotography enthusiasts amongst their listeners to shoot + share images of M90, a spiral #galaxy in Virgo. Here is my attempt telescopius.com/pictures/vie...

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 www.youtube.com/watch?v=3nOU... #astronomy #astrophotography

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. telescopius.com/pictures/vie... #astrophotography #astronomy #celestron

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. #astrophotography #astronomy #parallax #stars

Expansion of M1, the Crab nebula over 20 years. #astronomy #astrophotography My @celestronuniverse.bsky.social EdgeHD 9.25" compared to the @stsci.edu Hubble Space Telescope

I am still enjoying to compare my own #astrophotography images to those of the #HST and #JWST run by @spacetelescope.bsky.social. I improved an edit I did on Stephan's Quintet. 95x180s @celestronuniverse.bsky.social EHD9.25" ASI294MC Pro L-Pro filter.

I think I need some help from an actual #astronomer like @drbecky.bsky.social. Please share if you know someone who can help me identify the high proper motion stars in my comparison of M51 with a 20 year old @spacetelescope.bsky.social HST image. See 🧵for what I've found so far.

I am an #astrophotography nerd. So I have been asking myself a question ever since I started using @bsky.app No, it doesn’t seem to be an actual starry sky that shows when starting the app 😅 #platesolve on nova.astrometry.net

Did you see my attempt to shoot M51 yet? Take a look at my profile for more info. Tonight I am adding Ha using the #optolong #LeXtreme filter. My #ZWO camera is doing just fine with it! @siril.org does the rest 😇💪 This is just a teaser…

Work in progress. M51 has somehow evaded my attention in my #astrophotography. I have some sets of data on my harddisk, but nothing to really be proud of. That is going to change, now I shoot it with the EdgeHD 9.25”. Perhaps I should start adding L-eXtreme data to it. 56x180s so far

A month ago I posted about an Einstein Ring which I photographed with my backyard EdgeHD 9.25”. Since then I added more data (611x180s) and with careful processing it got a bit clearer still. See #Hubble image for comparison. @celestronuniverse.bsky.social #astrophotography #astronomy @siril.org

Last week I shared a small clip of my rig. With it I have been imaging very small targets lately. The Celestron EdgeHD 9.25” at f/10 brings me real close in to targets. I enjoy comparing my images to those of the famous Space Telescopes (JWST and Hubble) Follow for more #astrophotography

Let me introduce you to my telescope setup #astrophotography automation. !Not sponsored by #zwo! - Celestron EdgeHD 9.25” - AM5 Harmonic Mount on an iOptron Literoc tripod. - ASIAIR Plus control computer - ASI294 MC Pro (main camera) - An ASI174 MM (guiding) - Celestron OAG - EAF focuser

Work in progress #astrophotography But what about youtube.com/koplamp you ask? Yes, indeed… I distract myself constantly from working on videos. Apologies! Any video in particular that you would like to see?

A week ago I shot almost 300 images of 10 seconds each with my Celestron EdgeHD 9.25". After stacking with Siril and processing I got to this result. I processed the image to accentuate the bowshock around the star LL Ori. @celestronuniverse.bsky.social @siril.org #astronomy #astrophotography

Work in progress! 99 photos of 3 minutes. Stacked and processed in @siril.org Will add more data once I can. Downloaded and processed Hubble Space Telescope data too and processed it similarly. You then can see the Einstein Ring CSWA 1 more clearly. en.wikipedia.org/wiki/Cosmic_...

Wishing for clearer ways to educate people to the downsides of #lightpollution. So much of nighttime lighting is unneeded and often unnecessarily pointing into the air. Most people don't see it as pollution, shrug their shoulders and close their blackout curtains to be able to get some sleep. 😢

Sirius is the brightest star in our skies. If shot handheld and a tiny bit out of focus, one can create wonderful images, as masterfully shown here by Steve.

I couldn't resist shooting the well known target IC434 which goes by the English name, Horse Head Nebula. Just 32x 180s on my EdgeHD 9.25" and an ASI294MC Pro camera. Edited using Siril and Graxpert (did I go too far?) @siril.org @celestronuniverse.bsky.social #astrophotography #astronomy

Last night the EdgeHD 9.25" was aimed at a patch of sky in the Big Dipper, Ursa Major. Specifically the interacting galaxy group known as ARP104. Processed using Siril and Graxpert. 51x 300s ASI294MC Pro (L-Pro filter) @siril.org @celestronuniverse.bsky.social #astrophotography #astronomy

My telescope finally got some time under the stars again. Not sure if I can produce nice images out of the data. This one shot was funny to me as apparently an airplane flew right in front of my target. NGC 2261, Hubble's variable Nebula. #astrophotography

Yesterday I temporarily switched from my regular IT job to being a schoolteacher. I taught the kids about telescopes. They even got to use some (to search for birds in the trees) #outreach #astronomy #careerswitch?

This is a beautiful representation of the entire year. Cross referencing it with my image of my ASIAIR logs you can determine that my low amount of #astrophotography is not merely due to cloudy nights...

The winter night sky (& Jupiter) through the canopy of an old Dartmoor oak. I’ve been trying to get this exact shot with this tree for a number of years, but sky conditions/positioning never worked out. Finally it all came together on Thursday under bitterly cold, clear skies. #astrophotography

#ASIAIR #wrapped #YearInAstro 2024 was a terrible year in regard to my #astrophotography. I save all the logs of my ASIAIR and as such I can generate a graph like this. I am in a bit of an astro-rut. My YouTube channel hasn't had a video upload for quite some time too. 2025 can only be better!

Played with a Meade 8” telescope that was said to have some issues in the goto pointing. Didn’t find any. Just for giggles attached my iPhone to a 20mm eyepiece for a 30s exposure. #astrophotography

I have two telescopes and two mounts. For a long time I haven’t used the #CEM40 and the William Optics GT81 with ASI2600MM Pro camera. The reason: the #ASIAIR Pro on it had died. I tried an iOptron iMate but couldn’t get it to work. Spotted a good deal and bought a 2nd ASIAIR Plus 256.

Kevin's post reminded me of February 2023 when I too shot this target with the intent to catch the Merope nebula. You see Merope destroying a blob of gas, also famously imaged by @nasahubbles.bsky.social (see inset). 3rd pic was my full FOV on @celestronuniverse.bsky.social EdgeHD 8"

Saw a tweet about a WSJ article. The photo in the article makes me think of Vermeer. I think it is the window on the left that triggered that thought. The colors too. www.wsj.com/world/americ...

Hello! My YouTube channel now has almost TEN YEARS of Astronomy & Astrophotography videos! Here are 240 of them... Thanks to everyone watching. It's hard to believe I'm still going but honestly - it's a joy. Clear skies! 🔭📺🪐 youtube.com/DylanODonnell

So… uhm… hi there! In case you stumble onto this account, I take photos of our night sky. Mostly through telescopes. And I like to explain how I got to my results. Hence I have a YouTube channel too. YouTube.com/koplamp

How is the butterfly doing? The bird seems to be crossed out by many. I should probably start following the same peeps I did there

Hello BlueSky… any good suggestions who to follow here? I am a YouTube wannabe in the #astrophotography niche. Having fun. Not too much pixel peeping. That’s my thing… My latest vid? The Easiest Way Achieving OAG Focus With an ASIAIR and EAF youtu.be/-9A6L43k3Vs
