Who has the Knobs?

[magician]

While the collimation on my new scope appears O.K. (What do I know?) at the moment, I have ordered a cheshire from Steve for use in the future,The idea of "Bobs Knobs "seems to me to be the way to go,can I buy them in the UK? or failing that does anybody know the thread size? This is for the Explorer 200

Lo Frank

From memory Bob's Knobs are only made for Mak's and SCT's ie: those with fiddly little screws in the middle of the corrector plates. Your 200 should have chunky collimation knobs on the base

Thanks for that Moon Plodger, I thought the Knobs Idea would do away with the phillips head adjusting bolts that I feel could get a bit fiddly

If you do find out what size the thread is and the length in total you could always change them out for some Cup head sockets, so You could use an allen key instead of a pozidrive.

I will never be able to understand the use of pozidrive screws on telescopes and mounts as the heads easily damage and it is sooo easy to slip and scratch something or worse damage yourself :nono:

most of the tubes come out of china/tiawan now, including the lightbridges and synta stuff so I cant imagine the threads being much different. I would just e mail them using the contact form on the website to check first though. its a damn good idea and one I might try myself next year if yours are successful

You have got me thinking...

Once the dust settles after Xmas, I'll make some enquiries and see if I can't put together a collimation screw upgrade set :thumbleft:

I'm sure I saw a thread about Gaz's Knobs a few months ago, but I can't find it now. Gaz did this and stuck some pictures on about the modification.

Hi Frank,

Open up yourself an 'iseestars' account.... If you look at the bottom of the SGL page, you will see the logo, click on it, and sign up!

When you have done that, I or someone else will talk you through the rest... ok?
