Int. Space Station 07-03-2009 by Chrissyo Int. Space Station 07-03-2009 by Chrissyo
My first International Space Station fly-over of 2009!

I’ve been looking forward to this one for a while, I haven’t had a chance to catch any for the last few months. This pass was nearly ruined by clouds – the entire sky was covered by that nasty light wispy stuff when the ISS went over. I didn’t even pop out from behind them until it was near its maximum altitude. Hence why each of the three ISS frames in this image has a different brightness – they were taken through different amounts of cloud throughout the course of the pass.

The top three images are the raw frames pulled from the AVI (except I brightened the left image a tad). The bottom three images have just been enlarged by a factor of two and have been sharpened slightly.

For capture I used my 10" Newtonian telescope on a Dobsonian mount - I hand tracked the ISS visually through my finderscope. The camera used was a DMK21AU04.AS with a 2X barlow lens.

Certainly some of the nicer ISS shots i've seen. I've yet to take a stab at it myself though i don't know how well they will turn out with a DSLR. I'll have to try and see i guess.

My shots still leave something to be desired.

I think I need to get a knife edge focuser and a much longer FL eyepiece for the projector.

I got some good shots using prime focus but the images are too small.

My technique is to use the Telrad to track and just keep shooting frames until I am done.

I agree with you about the luck part!

Awesome, hand-tracking it through the finder must require some skill..
Is it possible to get a sharper focus though?

Thanks. :) Though it doesn't really take much skill, just a bit of dumb luck that you get anything on the CCD. =P

As for focus, yeah, it is possible to get sharper focus. The main problem this evening was that the seeing was pretty bad (because of the clouds) and the sky was still pretty light when I was setting up/focusing so it was a bit difficult to tell whether the object I was focusing on - the Moon - was completely in focus or not. Also, the fact that the ISS darts around over the CCD doesn't help too much. =P

I always love it when you snap the space station :)
