Collimating screws all tight on Celestron 6se

[cumbers]

Hi, Please can anyone help, I am trying to collimate my Celestron 6se, it is a little bit out, but the adjustment screws are rock solid. I have had the scope from new for about 6months and this is the first attempt to try collimating, if I try too hard it is stripping the head of the screw. Any advice please.

Does it have lock screws next to the adjustment screws? If these are locked down they will need to be backed off. I've only used a dobsonian, not a SC scope however.

One thing about small fasteners or any stuck fasteners, you only get a few chances to loosen it before the head starts to round out. Make sure the hex key etc you are using is the proper size, am sure you realise that. If I have an internal hex round out, my next move is to gently tap in a torx head and see if that will grab.

Shouldn't be any lock screws with an SCT, just the three small screws on the secondary cover. I think they're screwdriver screws as opposed to cap head??  First thing I'd check is if the screwdriver us the right one for the screws, I.e. Phillip's, pz1,pz2 etc. I'd use a good screwdriver with a grippy tip like a wera. 

Are you absolutely sure it needs collimating?

Thanks for quick reply, there are just 3 screws don't appear to be any lock screws, they are philips head screws not hex. Thanks anyway

You can only adjust the secondary on an SCT. There are no collimation adjustments on the primary.

There are no lock screws on the secondary - just 3 cross or hex screws. You sometimes need to loosen one a little to be able to adjust another one.

When I look for the 'doughnut' shape when out of focus on a star it looks like it does need collimating, however i have got a reasonable result from some amateur photography thru it so maybe just leave it alone.

Thanks John, yes they are the screws I were trying to move.
