Re: [APML] off-axis guiders

Hi friends,
I have decided to get an off-axis guider for my telescope and I would like to have some advises on which OAG is best for my setup.
 
That's the best choice.
 
My telescope is an 8" f/5 F1000mm Newtonian with an EQ5 mount, dual axis motor drive and drive corrector. I can use both 1.25" or 2" focuser on the telescope. I also have a barlow x3 lens and a 10mm reticle eyepiece.
The two off-axis guiders I'm thinking of, are:
1.  Lumicon Newtonian Easy Guider
2. The TAURUS Tracker III
My other question is, is it better if I use the 2" focuser than the 1.25?
 
I'd recommend the Lumicon simply because I'm familiar with it and I know it is a proven performer. You'll need to use the 2" focuser. I don't think it is possible to use a 1.25" focuser with an OAG and if it was you would have severe vignetting.
