Hi I'm new to the forum and getting back into astronomy after about a 15 year break.
I have an Orange tube Celestron 8 SCT which has just had the optics cleaned and collimated.
On checking the wedge angle with one of the new digital levels, I was surprised to see that the angle was set at about 56 degrees. My Lattitude is about 33.5 degrees S.
All of my books say to set the wedge angle to the same as your Lattitude.
This morning I found the following excellent article by Chris James on this board...

Chris says to set the angle to "
complimentary angle for your lattitude" which using his formula of (
90-your lattitude), would put me at an angle of about 56 degrees, which is where mine is set.
Why shouldn't I be setting it at 33 degrees??
PS. I am a Math Free Zone
