Collimating my Skywatcher 150 and 130

[Leegsi]

How do I collimate my Skywatcher 130 and 150?

I have a laser but not 100% sure how and what to adjust.

This is what I have:

I centred the laser by turning it in the focuser and adjusting the lasers grab screws till the dot didn't move on the primary mirror.

Thats as far as I got lol.

Is that a proper laser collimator?

I would re-check the centring/calibration of the laser by using a V block and a mark on a wall. This would eliminate any inaccuracy imparted by the focus draw tube and or slop

This video will show you what to do. Laser collimators after the bit by eye!

Cheers, Thing , I used to have that guide in my "favourites", but when my last PC died I lost all of that stuff, so its now back in my favourites. That video combined with Astro-Babys guide should solve any collimation problems.

The two are invaluable. When you buy a new scope you should be given links to both websites and a copy of Turn Left by the manufacturers!

Thats great

Thanks

Better still some scope manufacturer should buy the licensing to my guide as an exclusive - I'd even sell it cheap. Dont want much really. celestron could have it for a CPC 1100 - SkyWatcher could have the same for a similar deal

Superb and thanks for this.

I just had a chat with a dealer about one or two things, who basically suggested I was a chuffin nutter for buying a 150 newtonian as my first scope....

How you going to collimate it ??? It won't be as good as a refractor - spend the money on a refractor and you won't regret it.......!!!

Thanks to this guide, I think I can manage to collimate and the guy was just an opinionated old duffer - praps. But there you go.

Thanks for all the efoort put into this guide. I am now calmer about my purchase.
