Details:

Timing of GOOD ISS passes and GOOD weather at the same time have not bin good at my location lately. I just had a ISS pass of 80° on 6-03-15. It was very cloudy. This ISS image was taken with a very small short brake in the clouds. I also thought I would share a part of how I processed this stacked image.

My camera and Software settings:ISS
FireCapture v2.4 Software
Camera=ZWO ASI174MM
Filter=Orange
Profile=ISS
File type=SER
Bit depth=16bit
ROI=800x800 for ISS and my setup Edge HD 14 1.6 x barlow
FPS (avg.)=64
Shutter=1.038ms
Gain=60
Sensor temperature=27.8 °C

Please note:
FireCapture v2.4 Software gives you a running log list of your frame numbers.
If I record at 64 fps. I will look at each 1 sec. 64 frame sets and see what ISS images are in the frame or sharp.

Example: if 14 frames out of 64 frames pre 1 sec. of recording time were sharp. I will only stack the 14 sharp frames. Also 1 sec. of time is ok to stack ISS images without ISS movement.
This can also be done with manuel tracking with high speed camera frame rate. As long as your manual tracking is good enough to get more frames in a 1 sec. set of time. As I said: a fast frame rate camera will give you better odds of getting more ISS fps images in a 1 sec. recorded time frame to stack.

Kind Regards
Philip Smith

This is an incredible capture! Many thanks for sharing your processing information. I am curious about how you focus the object.

Hello John Sedlacek, I will focus on The North Star, Polaris with a Spike-aTM Bahtinov Mask http://www.spike-a.com/?gclid=CIGf8u2Z_8UCFZGQHwodMkUAIg and also check my telescopes collimation. You can focus on Moon, Jupiter, or Venus if in the sky. ISS Focus Example: If ISS Max pass is at 70°.....You want to look for a star around 70° to check your focus. I also us a motor focuser. Hope this helps you.
