My ISS webpage created with notepad http://jimmyjujames.com/ My ISS passes on youtube https://www.youtube.com/user/jimmyjujames/videos December 3, 2015, 6:18 P.M. CST (UT-6) Sun 18 degrees below the Western horizon. ISS Phase angle = 73 degrees (Sun-ISS-Telescope) A value of 0 indicates full phase, a value of 180 indicates new phase. ISS approached from SW ISS reached 86 degrees altitude in NW, range 259 miles. ISS departed to NE This ISS pass was above the trees for about 61 seconds before going into the shadow of Earth. Vanished when descending to 70 degrees altitude in the NE Most leaves have fallen and I was able to start tracking the ISS through the tree limbs. Collected 880 frames with ISS on sensor. Used 722 frames in final avi. Mount: Astro-Physics 900GTO GEM The 900GTO has features that allow me to track the ISS in the daylight without a meridian flip at zenith on some passes. If ISS approach is from the Southwestern horizon to Zenith and departs to the NorthEastern horizon then no meridian flip is needed. Set meridian from 0W to 6W (western horizon). 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." 10'' f4.5 Newtonian TIS DBK41AU02.AS color cam at prime focus FOV = 17x13 arc-min Satellite Tracker v2.5.1 Satellite Tracker Setup for my Astro-Physics 900GTO GEM Mount with a 17x13 arc-min FOV. 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) You will need to change the following 3 options as you change your eyepiece FOV 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 Wiring setup: Laptop#1 Controls 900GTO mount and Joystick USB to Serial adapter 4? foot 15 foot serial cable to top Com port on GTOCP3 on mount USB transceiver for cordless Joystick Laptop#2 16 foot USB cable with 20awg power leads. 5 volts at laptop 4.84V at TIS DBK41AU02.AS color cam Cam at prime focus on 10'' f4.5 Newtonian. 17 x 13 arc-min FOV RoboFocus Firecapture v2.4.12 captured ISS as an avi movie Gain = 501 Shutter speed = 5.0ms after ISS moved into shadow of Earth Lossless 'Ut Video' codex Procedure: Set both Laptop and 900GTO mount clocks to within 1 second. Focused and ReCal'ed on Enif In Satellite Tracker, click "Connect" button to connect to 900GTO mount. On 900 Keypad set Meridian from 0W to 6W Counter weights above horizon in the East Scope is close to pier on West side and pointing above the SW horizon. The ISS approach is from the SW. Clicked Start Tracking button after ISS passes scope. On a Good-Day after pressing the "Timing Offset Coarse" button 1 to 3 times, I see the ISS move through the Cam FOV. Then I click the "Timing Offset Fine" button in the opposite direction and hold the ENTER key down until the ISS is back on sensor. After ISS is on sensor, switched from Buttons to Joystick control An accurate polar alignment will result in less joystick corrections.
