Laser Collimating a Newton Skywatcher CF-10" f/4

[nandopg]

Dear Friends,
I've collimated my 10" f/4 using a method that I derived, using only a barlowed laser from Howie Glatter and a Cheshire from Fairpoint Astro.

The image shown below was obtained through the Fairpoint Cheshire hole after the collimation procedure has been carried out.

I always used a star test to properly collimate my Newt so, for this method in day light, I would like to hear what you guys think about the result shown in the picture.

Thank you,
Fernando

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

Fernado,
Looks pretty good to me.
I used to have a 6" f3.6 Schmidt Newtonian and the visible off-set was significant.
