Precise and easy to use template!

This is a must when collimating with the Catseye system, the sticker is easily mounted on the mirror with the template, and the sticker is very reflective so it is very easy to collimate with this.
I made a short video of how to mount the sticker, it can be found here: https://youtu.be/qgYr23RB4ME

Catseye Centring Template
Friday, 21 February 2014 | Jake
Whilst it's possible to produce your own centring template, the Catseye template is very nicely printed on durable clear acetate film and accurately printed/marked. It came supplied with hotspot and clear instructions in a cardboard mailing tube. I was initially concerned that it might be curled and require flattening before use, but the acetate unrolled out flat with no observable distortion.
As I have multiple mirrors to spot, FLO were very helpful in supplying 3 additional hotspots with the template at nominal cost.
I spotted two 8" mirrors single handed and spent longer removing the old spots than applying the new.
Very simple, precise and quick to use - though you may require another hand for the bigger template and larger mirrors.
As an aside, the previous centre ring on my skywatcher mirror was 2mm off, which @ F5 is not accurate enought (2.8mm sweetspot with a radius of 1.4mm)
