Newts at f/4 and the different sizes and optical configs for fast newts means the secondary can be offset etc like your photo shows. I don't think it really matters what the photo shows ... how does a star test at night look? If it looks good then share your method (if its new method)!
Personally, I detest lasers cos they themselves need collimating or can give bad results ... and collimating those suckers with their 3 little screws is a nightmare. Well it is for me with shaking hands! LOL. Although the barlow method gets around badly colimated lasers (I think?). Anyway ... like I said ... how does a star test look? If that looks great then share your method. Cheers
