I hope this is not "inappropriate" for posting to the group, but here it goes:
Raphael, have you considered perhaps a different type of setup for tracking the ISS? For example, there are Astro-Physics mounts out there that when paired up with software like APCC [Astro-Physics Command Center] it helps a lot when tracking satellites, ISS, Hubble Space Telescope "HST", etc. Not sure, but I think also the Software Bisque Paramounts can be programmed to do the same thing <The Sky X software, T-Point, etc>. I figure the extreme CNC precision machining that goes into these mounts would make the task/goal easier (however, with a smaller aperture scope).
I mention this because many astronomers have multiple setups (mounts: alt-az & German Equatorials, push to or electronic drive systems, solar or nighttime telescopes, etc)
I know not everyone is into German Equatorial Mounts "GEM's". They are a different animal, or beast, versus a big dob light bucket. I mentioned it here as "just a thought" or "friendly suggestion".
Perfectly understandable if your preference is to stay committed to your project.?
I hope this doesn't get me banned/ kicked out of the group. I don't think it hurts or is harmful to look at alternative means of doing things.?
