skywatcher collimator
The only collimator in stock at my local telescope shop is a skywatcher collimation tool. I asked him if this was a sight tube/cheshire combination tool and he said ???????.
He described it as including a mirror and cross hairs. I had a look online and from the outside it does look the same as Orions sight tube/Cheshire combination tool.
Is it? Any reason not to buy this for my 8" F/3.75 newtonian?
