International Space Station (27/03/23)

[Kon]

I bought a new mono camera, asi462mm, recently and ISS was predicted to pass over UK at 2106 UTC tonight. Despite the clouds I managed to get some really decent images. I am really excited to try it under good seeing conditions. 8" Dob, manual tracking, asi462mm, UV/IR cut filter, 2.5x TV powermate.

Terrific image. I saw it pass over - not nearly as interesting with the naked eye 

[carastro]

Amazing image.

Wow that's awesome 👍

[cloudbuster]

thats better than ive seen published elsewhere...well done you!

[callisto]

Nice capture Kostas 👍

That’s brilliant! It’s things like this that want to make me buy a camera. And a PC…

[Space Cowboy]

Terrific capture! 👍

You have until 2030 before it is de-orbitted. 🥲

There have been some excellent mobile captures here (see the posts from @ankwste) but you will need some way to process the videos.

The obvious thing to do is give it a go with what I have. Even if it doesn’t work it’s all experience! I’ll have a think and a play.

I am happy to return the good karma of getting a camera on loan from sgl recently, so if you want to try, you can borrow my colour camera but you will need a laptop for it.

That’s most generous! I’ll see what I can do.

Amazing image Kostas, well done

Just to look up and watch it pass overhead as a bright dot, most people would never believe the detail you are able to capture.

Well done!

any chance of a quick walkthrough of your process ? I'd love to do this.

For capture, I aim for 40% histogram; I use a star of similar brightness to adjust settings. I then use the same for every fly over. I shoot a continuous video at  640x480 ROI for max fps but you can use the full sensor too. The above was with full sensor. Exposure between 0.7-1ms and gain to have the 40% histogram. I never capture if max pass is less than 60degrees as the atmospheric disturbance is awful. I start my video at 45-50 degrees and rising. I follow it with my RACI and never look at the laptop. I have done it so many times that I know the trajectory on my sky and I place the RACI a few degrees ahead to avoid motion noise.

For processing, I use the ISS setting in PIPP with 70% white balance. I then go manually through my tiffs. if I have a sequence of continuous images of ISS with high details I stack them in as!3. Then a bit of registax and maybe astrosurface to bring the colours when I shoot in colour. 

 

Feel free to message me if you want more details. I hope you will manage it.
