hi . i have just taken ownership of a 8" newtonian and I would like some advice on a collimating tool.
I will be using it mainly for visual use but i may want to use it for imaging sometime later, so i need to get something that will collimate it accurately enough for imaging in the future.

what is good to use here.
i was looking at the 1.25" howie glatter barlowed collimater.
will this be a good one to get?

i know nothing about collimating . have never had a reflector before, just refractors, and a mak.
