C/2025 A6 (Lemmon) captured with my usual and modest astromodified a7III at 600mm since I don't have a dedicated camera. By pure chance, I was able to try the Sony 200-600mm a couple of nights ago. My intention was to make a few tests, to shoot Andromeda, Orion, and the Pleiades just to see how they look at 600mm, and I thought of giving the comet a try. I was shocked when I saw it on the camera, and after a while of trial and error, I was able to stack 23 shots—not much more than one hour of integration. For me, it’s the first time I’ve shot and finished a photo at this focal length, and this comet was a great experience to start with.

Stunning. It’s closest approach will be on October 21st.
If Carl Sagan was alive he would have this framed
How long is that tail feels like it’s pretty long!
This is amazing! Thanks for posting all the capture info
What time would you recommend trying to get shots at? I live in the Eastern US
Awesome picture. I hope you submitted it to APOD!

Beautiful photo! I love how the background stars behind the tail make it look like it is sparkling!
A splendid shot.
This is a fantastic capture.
Cosmos
I just wanted to say “Cosmos”, but I need to fill 25 characters
I stumbled upon this post on the front page and wow, what a great shot! I don’t know if this makes any sense but pictures like this fill me with gratitude that we have the technology to see this kind of stuff. Truly amazing!
Really good picture. This would look good on a wall.
It’s so beautiful. I wish we could see it with the naked eye like that.
That would be a cool lithopane. Or a print to frame. Genuine photographers are getting lost with all the AI slop. Nice work.
Absolutely stunning shot!! Thank you for sharing!
That’s fantastic! Is this something a novice can attempt? If so I see a Ted talk in your future.
I had to read the comments to make sure this was real. Absolutely amazing. Thanks for sharing.
Wow. Amazing shot. Please post again on the 21st if you can get it.
