View Full Version here: : Optical cleaning and collimation
Folks any one know of anywhere in the Australia that cleans primary and seconday mirrors also recollimates them as well. My tak is out of collimation and i don't want to touch it. So i thought i might as well get the mirrors cleaned at the same time.

I think Don Whiteman at Binocular and Telescope Shop does a great job of cleaning and collimating telescopes. From memory they have a 10" collimated beam for collimated light source.

Hi Ian
On the next clear night when we are both free, you are welcome to drop by our place and we could have a go at collimating the 'scope?
Might even get to try the Kendrick SCT collimator which I have not yet used.
Cheers

Dennis many thanks for the offer. But i have already arranged to have the scope sent back to Takahashi to have mirrors cleaned and recollimated.
Thanks for the offer Dennis
Cheers

No worries Ian. With the current Brisbane weather patterns, it looks like it’s going to be astronomy indoors only, for a while!

Hi,
Just letting you know that York Optical at 316 St Pauls Terrace PH-:07 32522061, will collimate your scope, they quoted me $60.00 to spot the primary and collimate a 150mm/750 Newt. (Don't ring but E-mail them for quote!- see link on your right)
My advise though is to learn how to do this yourself, this is as well a cleaning the mirrors. Once you know how - it is simple - see section in projects & Articles on cleaning etc(if you require distilled water I have plenty to share). I just finished spotting, cleaning and collimating my short tube 150mm/f9 (which are quite tricky because of the corrector lens and its degree of precision it requires.
I have a Celestron Combination cheshire/sight tube as well as a Saxon Laser Collimator, I also am buying one of Jim Fly's Catseye's. You are quite welcome to drop around if in the area and I will show you how to go about it. It can be quite frustrating to the newbie as I just found out.:)

Collimation is a skill all newt owners need to learn. To pay for it is overkill in my opinion. Take yourself and your scope to a star party or astronomical society viewing night, and you'll get advice from experts who'll do it for free! And you'll learn too, which is much more important.

Just another point here Ian, where i the scope being sent (how far and by what method)??
If it is going by courier or post there is a 98% chance the collimation will slip a bit in transport after the re-collimation. I stongly suggest if you are paying for the service that you pick the scope up yourself from the shop, if possible.
I have had five scopes, all newts delivered to me by Australia post (E-bay)and every single one needs to be re-collimated! Rough handling, I have seen couriers drop large boxes etc regardless what warning labels are evident! My new 150mm/f9 was dropped to the ground by the posty taking it out of the van when he delivered it, I saw him do it and it had Fragile in large lettering all over the box. Gave me a hell of a problem in re-collimating, but also this Is the one made me do the research on the subject and ask questons, taught me how to collimate a Newt.
