ISS Through the Webcam Take 2

Yesterday I tried l capturing the space station through my telescope webcam but my shutter speed wasn't set correctly.

Tonight I had a higher (57 degrees) and brighter (-3.5) pass, but it wasn't a full pass. The seeing want very good, there were hazy clouds out, and I didn't even spot the station until it was 25 degrees or more above the horizon. Still I thought it would be good practice.

I collimated the telescope, dialed in the focus, and aligned my finder scope as best as I could. I set the shutter speed as fast as it would go, which I think is 1/1000 sec, and had the gain set to the max of 255.

At that shutter speed I definitely froze the motion in the frame, but the camera is barely able to see the station.

The structure of the station is clearly visible. The Russian segment is vertically oriented but on the bottom. US and European segments are connected to the Russian segment but on the upper part of the image and form an L shape. The to bright spots are the radiator panels. The truss and solar panels aren't visible.

I'll have to experiment with nudging the shutter speed a hair slower to bring the brightness up, though going under 1/1000 second shutter speed is generally not recommended for the ISS. With this camera I may only be able to do the brightest and best passes.

Hopefully the weather will cooperate in the next few days for two 70+ degree passes. If I crank up the frame rate I could possibly do some image stacking to improve the sharpness as well.
