I have imaged back in 2015-16 using =x193iq5w xeuugli x13faqbe x1vvkbs x1xmvt09 x1lliihq x1s928wv xhkezso x1gmr53x x1cpjm7i x1fgarty x1943h6x xudqn12 x3x7a5m x6prxxf xvq8zen xo1l8bm xzsf02uSky-watcher 6 inch manual Dobsonian & ISS view captured through Canon 550D DSLR. (Check image attached)
Used simple hand tracking method to keep ISS in crosshair center by looking through the finder scope.
That method was workable in case of fully manual dobsonian mount.
Now I no longer have dobsonian telescope. I now use ZWO 1600MM-PRO, GSO 6 inch RC and Ioptron iEQ45-Pro GOTO mount.
Want to know how to capture ISS as it is traveling at high speed for the scope/mount to track.
I have seen people captured some great images of ISS using much higher focal lengths like C8 or upward.
Is there any particular tracking program for guide scope to track high speed objects like ISS or they do manually, want to know how?
Thanks
