This is an interesting discussion. I have the exact same scope as the OP. As I do not currently own a TAK collimating scope, I am proposing to have a crack at collimating it using the other methods. I will start with the Cheshire and then use the HG laser method. I expect this will get me close. As I have taken several images using the scope as it arrived (and I know it is quote out collimation wise) I think this will enable me to make a reasonable, although maybe not very technical, assessment of the value of those methods.
Once my bank balance recovers a bit from the recent purchase of mount, scope and bits and pieces, I will get a TAK and see how that goes.
Hopefully be able to provide a bit of a report!!
Cheers
Malcolm
