Poor Orion ...

Yeah, well, the ISS was actually moving right to left in this image taken on Feb 27th.

Canon 40D, 17mm lens, 8 sec at f/4.0, ISO 400. (Heavily cropped!)

Hi Brian. Did you try 30 seconds on Orion?

As it happens I had the camera set up ready for the ISS pass - but switched off - whilst I set about setting up my scope. When the ISS came across I just switched on the camera & fired. It was set for 8 secs at f/2.0 (standard for the photometry work I usually do with this camera) and, f/2.0 not being available on that lens, 8 secs at f/4.0 is what I got. Worked rather well I think. 30 secs would probably have been OK with a 17mm lens but not with the 50mm lens I usually use, considerable trailing of the stars would undoubtedly have been visible.

Thanks, Brian. I didn't think you would get star trailing with a 30 sec exposure but I guess with Orion, being on the celestial equator, would suffer more than most constellations. As I can only get 8 secs exposure on my compact digital camera, I don't get star trailing without using a telescope.

So it was a "through and through" [:)]

Managed to catch the ISS the previous evening when it passed above Orion. Unfortunately, between achieving focus in readiness and taking the image I must've nudged the focus ring a fraction, so the stars and trail aren't as sharp as they could've been
