Hi all,
I know there are many collimation methods out there, some visual based, some software assisted, others supported by simple to complex third party devices. I know, as I have beat up myself trying many of them to find the right solution for me, my equipment and my purpose for astrophotography.
The scope type I'm talking about is one with a fixed primary and an adjustable secondary mirror. I've now tried it numerous times, and now on my Planewave 12.5. I hear that people think this is a forgiven scope to collimate, but to get it right, it has been still challenging. Anyway, if you're interested in having a read on an alternate approach and a variation on the single defocused star, see the link below...

I always think sharing is good, and I've learnt much more from others than I have on my own. So if this is helpful to anyone, that's great. It is simple, you can do it on your own, and it works.
Bye
Steve
