The Meade Lightbridge ones, as these fit all Skywatcher Dobs (except for the 8") as i have now found out

I had a look on Bobs site a while ago......is there a set that will fit a 10" skywatcher Newt. Primary and secondary and eq6 mount....

Hi Stu,

have you gotten any further with finding screws to fit the primary?

I was wondering if there would be a way around....maybe get larger screws i.e. longer shanks but with the same thread and the same length of thread as the original ones.

Then we'd need a way to anchor the body of the screw to the base of the mirror cell on the outside so that when you tighten the screw it pulls the mirror towards the base....

maybe even a screw with a lot of thread and some sort of locking nut to anchor it...

do you know how Bob's Knobs do it?

I might be way off track here, but just trying to find a way to get this to work....it just seems too awkward at the moment with the stock screws, and a bit of a bummer that Bob's Knobs don't fit....

cheers

I could open Stu's Skywatcher Screws

so let me get this straight stu, you want to have a set of thumb screws virtually to adjust your primary mirror. if so is it this kinda thing you are looking for

I have the Screws for the Secondary care of Bob's Knobs, as his work fine
But the Primary Knobs, the thread is too wide

Im currently looking into the sizes ect ect, ill get back to you once i have the correct thread sizes ect ect

Hi Stu,

Don't know the latest with your situation here, but Brendan was able to sort out a great solution for me.....now have completely tool-free collimation on both primary and secondary for my skywatcher 8" collapsible....

Thanks Brendan....taken the hassle out of collimation....

[Stu Ward]

If Brendan is out there listening, i would love to sort out the right knobs for the primary

I am about to order a set of secondary knobs for my skywatcher 10" flex dob. I find the factory primary knobs fine but I'm tired of using an Allen key to adjust my secondary.

Bobs knobs website lists the skywatcher secondary knobs in either 30mm or 35mm. Does anyone know which I should order?

Cheers
