Cheshire Collimation Eyepieces...


Recommended Posts

I have the cheaper of the two for 200p dob. It seems fairly well built but I've had 2 issues with it. Firstly, I can't see the 3 primary clips when centering the secondary in the focuser. I presume this is because it's a long cheshire. I've had to make a collimation cap for this part of collimation. Secondly, there is quite a bit of movement with the cheshire in the focuser, this means that the crosshairs don't stay exactly central when you rotate it. 

Please note that this is the only cheshire I've ever used, so I don't know if these are common issues with long cheshire eyepieces and the skywatcher focuser, or a problem with this particular eyepiece.

I'm using the same telescope...😉

I noticed, it's my first ever telescope, and I'm very happy with it. However, I have read that the focuser is not the best, and that might be causing the issue when rotating the cheshire.🤷‍♂️ If you go for the premium cheshire, I'd be interested to hear if you have the same issues with that

At this moment in time, only the Astro Essentials one available, so I'll wait till the Premium one comes back in stock...
