CDT (UT-5) Temperature: 55 F Humidity: 73 % Sun was 1 degrees above the Eastern horizon. ISS Phase angle = 91 degrees (Sun-ISS-Telescope) A value of 0 indicates full phase, a value of 180 indicates new phase. ISS approached from SW ISS reached 90 degrees altitude, range 254 miles. ISS departed to NE This ISS pass was above the trees for about 131 seconds. Collected 642 frames at 7fps with ISS on sensor. Used 590 frames in final avi. Mount: Astro-Physics 900GTO Equatorial Mount The 900GTO has features that allow me to track the ISS in the daylight without a meridian flip at zenith on some passes. This ISS approach was from the South-western to Zenith and departed to the NorthEastern. Set meridian from 0W to 6W (western horizon), tracked through zenith and no meridian flip was needed. 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 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 5 foot USB to Serial adapter 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 Laptop#3 16 foot USB cable with 20awg power leads. 5 volts at laptop 4.84V at ZWO ASI120mm mono cam Cam at prime focus on ZWO 280mm f4.67 finder scope 59 x 44 arc-min FOV RoboFocus Firecapture v2.5.05 captured ISS as an avi movie Gain = 486 Shutter speed = 2.08ms Lossless 'Ut Video' codex Procedure: Set both Laptop and 900GTO mount clocks to within 1 second. Focused and ReCal'ed on Altair Satellite Tracker: click "Connect" button to connect to 900GTO mount. On 900 Keypad set Meridian from 0W to 6W. Must be done after connect to mount. I think the connect to mount resets meridian back to 0W if it was at 6W before connect. Counter weights above horizon in the East Scope on West side pointing above the SW horizon. The ISS approach is from the SW. Waited for ISS to move above trees at 34 degrees altitude. Clicked the Start Tracking button On a Good-Day after pressing the "Timing Offset Coarse" button 1 to 6 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. Today's daylight pass was still dark enough to see the ISS on Finder scope Cam. Centered ISS on finder Cam and became visible on 10'' Newtonian. Adjusted brightness. After ISS is on sensor, switched from Buttons to Joystick control An accurate polar alignment will result in less joystick corrections. Post Processing: Virtualdub removed blank frames Pipp debayer GB to RGB Manually aligned avi in Regestax5 and saved as 512x512 Closed and re-started Registax51 Opened new 512x512 avi into Registax5, Auto-Aligned and saved as 256x256. Closed and re-started Registax51 Opened new 256x256 avi into Registax5 Auto-Align was jittery. Manually aligned and saved as 128x128. VirtualDub deleted poor frames and set final playback fps.
