Newtonian Easy Guiders

[John K]

Hi guys,

I am looking to potentially source a Lumicon 1.25" Newtonian Easy Guider for $70US plus shipping from America.

If I am using this with a new Canon DLSR 400D, is there any benefit in going to a 2" model at all? or does that only come into play whan I use film?

The unit will be used with a 12.5" Newtonian which is a truss tube, thus the idea behind not using a guidescope (dont think I will be able to attach it to my scope).

I gather that it will be hard to be able to use my SPC900 webcam to autoguide through the easyguider as the limiting magnitude will be around 6. Is that right?

Look forward to any advice you can offer.

John.

As long as the main optical path is 2", it doesnt matter what the guider port size is.
