Capturing the ISS with my Webcam

I've had some luck capturing the international space station through my telescope with an iPhone and then a mirrorless Fuji XA2. Recently I modified a webcam to take pictures through my telescope and I've been so blown away with the quality of the pictures of Jupiter I've wanted to see what it can do with the space station.

The main consideration when photographing the ISS is a fast shutter speed so the station doesn't blur across your frame. I tried exposing for Jupiter as a reference and I was worried the station would be too dim. I didn't take my own advice and left the shutter speed a little slower to make the station brighter.

Turns out I blurred the station too much and also over exposed the shot. I need to speed up the shutter speed a lot.

Most frames look like this:

But I was able to track well enough that I got one frame that at least has the shape of the station.

It's not the worst shot of the station, but it's definitely over exposed. The goal is to speed up the shutter to freeze the motion and more correctly expose the image. From there I want the highest frame rate possible, so hopefully I can stack ~10-30 images and really increase the sharpness.

I don't know if it will beat what I get with the Fuji mirrorless camera, but it's going to be fun trying!

Side note: I've discovered that my webcam has a frustrating quirk. Logitech has put the shutter speed backwards compared to most other webcams and the sharpcap software on my laptop can't correct for this. Unfortunately I may never know what the true shutter speed is for this webcam, I'll have to learn to dial it in through experience and reference stars.
