After a failed attempt this morning at 3:46am due to cloud cover, I received a notification that the ISS was to make another transit over Brisbane at 6:40pm Wed 6th November.:)
Having had the failed run earlier in the morning, I was better prepared although thin clouds still marred the views.:(
Here is a composite of 27 frames taken as follows:
Canon 7D fitted with 400mm F5.6L with Kenko Teleplus PRO 300 DGX 1.4x AF Teleconverter and Canon Extender x2 EF II giving an effective Focal Length of 1120mm at F16.
To minimise the effects of image blurring due to wild, unconstrained leaps of the camera/lens combo, I guessed an exposure of 1/000 sec at ISO1600 which was probably 2 or 3 stops under exposed once the results came in.
I’ve also included an image of the Moon taken with the same system, but at 1/160 sec although this has been down sampled, so the scale of the ISS and the Moon is greatly different.
Cheers
Dennis
