ISS my best so far

Recommended Posts


Another attempt at the ISS. This time Canon 100d and 1200mm which actually is a 200 f4 with a 2x and 3x on it. Managed to bang off 50 frames when it was directly over head. What you get is a tiny little dot in the frame. (Currently given up trying to track it with the scope). Pipp to crop them all and then stack.

First image is what I got from the stack of 50 drizzled at 3x, lots of CR which I got rid of by stretching the red away, then to B&W and play with registrax a lot. Result is second image. The lens is a very old M42 Pentacon 200mm but has very good optics, the teleconverter stack leaves a lot to be desired even for the £10 they cost me! So f24 1200mm @ 3200 ISO, 50 frames: half at 1/1000 half at 1/1600.

I'm pretty pleased with the result. Please feel free to grab the png and play with the wavelets.

That is very nice. To get rid of atmospheric dispersion problems you can also use the RGB align method in Registax.


Cheers for that. I tiddled around for about an hour on registax, kind of trial by error approach. Will have another try tonight if it stays clear.
