Thank goodness for Astro Babies Guide

[Kevdan]

Hi All,

I've been trying to colimate my 150p as good as I can since I got it a few months ago, and Acording to the manual colimation should be where the image is all centered and then everything is correct, BUT it is not like this and until I saw Astro Babies guide to collimation I would have been colimating for ever. This guide shows that a scope with a F5 ratio will be slightly off centred when looking at the reflected image.

So I am presuming that Skywatcher have made a generic guide to colimation for their manuals and DO NOT show that a fast scope will look the way it does. Which can be very misleading to many newcomers to this hobby including myself.

So Thank you Astro Baby, Keep up the good work.

Kev.
