November 12, 2015, 10:34 A.M. CST (UT-6) Sun 36 degrees above the SSE horizon. ISS Phase angle = 127 degrees (Sun-ISS-Telescope) ISS approached from NW ISS reached 89 degrees altitude in SW, range 251 miles. ISS departed to SE This ISS pass was above the trees for about 50 seconds. Many leaves have fallen and I was able to track the ISS through the tree limbs. Partly cloudy did not help either. Was not able to get ISS on sensor until ISS was departing. The best movies include the approach, pass and departure. I need to be ready, if I fumble on anything, no time to recover on this pass. Oh well, if so, as I've said for the last 9 years, "I'll do better next time". Collected 699 frames with ISS on sensor. Used 359 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.

Focused and ReCal'ed on Arcturus 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 less than 1 inch from pier 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. Overshot sensor 4 times. My Bad again! After ISS is on sensor, switched from Buttons to Joystick control An accurate polar alignment will result in less joystick corrections.
