Re: Anyone using RAPAS in Southern Hemisphere? Mach1 payload rating?
In the southern skies we usually drift align on a star close to the meridian on the celestial equator, such as Sirius, or any other one. It's dead easy, polar alignment here is not. PemPro has a really great polar alignment section, you can get pretty close to perfection in not an unreasonable period of time. Another way once described on this forum involves a two minute trailed star image in one direction, then back again. The 'wedge' pattern needs to be corrected in the usual way (altitude/azimuth) until it's minimized into a straight line. Once again - easy. My permanent setup is within 10 arc seconds of the pole in both axes, and if I wanted to spend more time at it could get it closer, but it shouldn't be necessary.

i wont be able to say about southern hemisphere but about payload, i use the astrotech 12 inch newtonian and works like a breeze. The weight is 30 kgs (however the place i live is not windy at all). Next coming to your polar scope it will depnd on you r latitude,i live at 13 deg N and Polaris keeps dancing ,so i wlll need to tune with pempro or PHD2 for fine tuning which takes ten minutes.
