ISS-TRACKING with Emmanuel Rietsch tracking system                2015

Beautiful ISS pass in BW/ Mount in AltAz mode ( all sky from WSW to ENE 70° culmination) - Wed April 8, 2015

Weather conditions were perfect but seeing really bad with heavy turbulence, Sun at -15°, sky clear, ISS really bright, timing of pass late enough to finalize centering all the optics and focus on low Venus !

There were 2 missed passes the days before mainly because of clouds at West, then after the ISS goes very fast and catching becomes difficult.
Moreover I was blocked by other mounts around this one ... and also forgot to align / use the Telrad !!
Telrad is the best to catch the ISS !
Nothing was moved from yesterday so I was ready 30 min in advance !

ISS aiming :
ISS northern pass !
To catch the ISS I was waiting while knowing where it would appear as a small moving star. Used the paddle. Catch Ok at first trial.

ISS Tracking :
DMK41GigE, Exp 0.01s Gain 0 !!, 15fps N&B / AD not checked. Foc: 180mm (FS60, 355 x 0.5) with reducer.
tracking was just fine until disappearance behind my roof ... not far from North, really to early :(
From the garden we (with David) could follow the ISS pass for at least 2 min more ...

ISS acquisition :
ASI 174MM capture on powerfull desktop PC (I7 950 @ 4gHz, Win7x64, 18GB RAM) with USB3 disk and USB3 active cable (5m)
Before pass base focus on Venus.
The Edge C8 was equipped with a 2x Meade APO barlow (resulting FL = 4m).
FireCapture 100fps, BW mode, 8 bits, Align-box & Cutout 668x484, Gain up to 355, 0.001s exposure, recording videos :
started at horizon 22:07TL in SER for 600s but aborted after ISS no more visible (10 GB final).
No IRCut filter used !
ISS focus adjusted with motorized focus (2" JMI)
Use of RegiStax5 CG mode (256x256 align area to small for export) and VirtualDub as usual...
Below, accelerated movie from registration and stack of 50 original frames for 1 final frame in AS!23 (70% good kept) :
