My best ever ISS

I'm feeling pretty happy right now! I've just come in from imaging the International Space Station from tonight, and I've captured my best results!

Details: 10" F5 Newtonian on a Dobsonian mount (I hand tracked the ISS through my finderscope). I used a 2X barlow lens and my DMK21AU04.AS. The settings in IC Capture was 60FPS, an exposure of 2000 (which was pretty much guessed at ... next time I might give increase the brightness a tad) and a gain of about 300 I think. I first had the scope on Saturn to get the focus right.

Visually speaking (through the finderscope), it was the best ISS pass I've seen! It went (from what I could tell) straight over Mars then right past Omega Centauri on its way out! Fantastic!

The images are shown below. I captured/processed the images on a different laptop to the one I'm on now, and it's screen is a bit brighter. As such, the image looked a tad dim on this computer. So I've played with the brightness a bit to fix it up. So the first image is suited for brighter monitors and the second image is suited for dimmer monitors. I hope. The third image is a quick attempt I made to throw a few frames into Registax and resample 1.5 times. It's pretty noisy, but I plan on giving it a much better go tomorrow afternoon after my exam.
