Hi all
I've just bought a second-hand Orion Teletrackto mount a widefield SLR on, and have attempted to follow the setup instructions to be able to track objects - or at least to keep them in my FOV for a few minutes at a time.
Living in Australia I've performed the latitude setup procedure - as the instructions state - for the southern hemisphere. This involves reversing the procedure that you'd carry out in the northern hemisphere - by setting the latitude FIRST, and then powering off before slewing to 0 deg and storing the latitude setup by pressing the "Fast" and "Slow" buttons simultaneously.
After I then go through the initial positioning setup, it doesn't track. I level the scope using a bubble level and then slew to due north (here it's 11 degrees east of mag north) and power down. On power up again it is in its home position - and after slewing to an object and putting it into Guide mode by hitting the "Guide" and "Slow" buttons simultaneously. Stars wander out of FOV at a rate that appears to be normal sidereal.
I then tried to align the home position to mag north - no difference.
I then tried to align it to true south and mag south - just in case the Northern-hemisphere-biased instructions forgot to mention that.
Still - no go.
It there a trick to these things if you live south of the equator?
TIA
