This ISS passing was a bright magnitude -2.4 reaching a maximum elevation of about 82°. The passing was just before the end of twilight so finding the ISS was extremely difficult. I only discovered that there will be a bright passing 20 minutes before it was about the happen so I was in a great hurry to get all the equipment setup.

I had a hard time finding a bright star to focus on so the image may be a bit out of focus.

I used a 1/1250sec exposure time with the gain set at 80% and the DMK shooting at 30fps (forgot to set it to 60fps ).

Overall, I am happy with these results. I could've used more gain to bring out a bit more detail but I am not complaining.

Can anyone identify any parts on the ISS?

Thanks for looking. :smile:

The Solar arrays at the left are clear.

Awesome work Matt.

I'm confused now though. When you say you did 30fps, does this mean that each frame is taken at a speed of 1/1250sec?

Cheers

Matt,
Ive been struggling to see the ATV in your excellent image, that is until I noted the date...:putz:

Next time perhaps.

Here is a reprocess of the same image.

What do you think?

Thanks Ray,

From what I understand is that every second the camera captures 30 frames per seond with a shutter speed of 1/1250 seconds.

Sorry that is a typo! :Oh_No:

This image was taken on the 29th of April.

Sorry.


Ooooo, great image Matt!:smile:

Thanks little legs. :smile:

Hi Matt

You are getting some great images of the ISS - well done.

I have often seen satellites zip across the sky - how long do you have from when you acquire the ISS until it disappears over the horizon?

See ya

Thanks Matt,

The ISS usually stays in a suitable position for a only 2-3 minutes or less.

So Matt how do you track the space station with the telescope. How long can you keep it in your FOV for imaging for?

Cheers

Hi Ray,

I wouldn't really call it tracking, more like shoot and miss.

What I do is try to keep the ISS in the Finderscope (RDF) and hope that I captured a couple of frames with the ISS on it.

It is probably not the best way to image the ISS but it works. :smile:
