Here is a pass I recorded with my Astro-Physics 900GTO GEM mount and Satellite Tracker v2.5.1
This is a new ISS web page that I'm having ftp problems with.
Site my come and go until I learn a bit more.
http://jimmyjujames.comAstro-Physics 900GTO GEM Mount. Purchased new in 2011
Upgraded to Rev ''V'' chip in my CP3GTO
Setup for my 900GTO mount.
Satellite Tracker v2.5.1
Timing Offset (sec) = 0
Alignment Adjustment (steps) = 0
Telescope> Interface Protocol> LX200 Compatible
Options--> Preferences--> Tracking Factor = 0
(0 delay between goto's results in about 29 GoTo's per second to mount on my setup)
You will need to change the following 3 options as
you change your eyepiece FOV
This is what I use for an 18x14 arc-min FOV (about 7mm eyepiece on my setup)
Options--> Preferences--> Timing Offset Increments Coarse = 0.5 second
Options--> Preferences--> Timing Offset Increments Fine = 0.01 second
Options--> Preferences--> Alignment Adjustment Increments = 1 step
Mount:
Astro-Physics 900GTO GEM mount:
Minimize backlash in Dec and RA
Set Mount time as close to the second as possible.
A very good polar alignment will minimize corrections due to drift.
The 900GTO has features that allow me to track the ISS in the daylight.
Southwestern horizon to Zenith to NorthEastern horizon and no meridian flip.
Wow! Super Cool mount.
Another user said this and I agree,
"The mount is so good that you just forget about it during the session."
Focused and ReCal on Vega in daylight
Track the ISS from SW to Zenith to NE with no meridian flip.
Start with OTA below horizon in the West pointing above the SW horizon.
After Satellite Tracker connects to mount,
change mount Keypad ''Meridian'' from 0W to 6W (overhead to western horizon)
Laptop
Download latest TLE's
Set Laptop time as close to the second as possible.
