Skywatcher Skyliner 200P secondary mirror

[Dom1961]

I have recently bought my Skywatcher Skyliner 200P second hand and I've noticed that the scondary mirror is held onto the adjustment holder by a sticky pad thing, is this normal?

There should be no sticky pad for fixtures, not normal, sounds like a quick fix for a broken holder, could you put a pic up, you may have issues when doing collimation depending on the use of this pad. I'll put a pic up to illustrate what it should look like.

You meant a double sided adhesive pad between the mirror backside and the stalk (holder), correct?

That is normal for many mass produced scopes.

Just checked. There is no sticky pad on mine

Are you sure it's a sticky pad and not a flattened blob of silicone sealant ?. Thats the stuff that is often used to attach the secondary mirror to the central angled boss.

Here is a thread on this topic from a couple of years back:

It looks like a sticky pad, it is quite hard to see so you might not be able to see it

lve just looked at mine and i cannot see a sticky pad on it,theres no gap in between the mirror and holder and i had me best specs on for looking.

Double sided adhesive pads is a common method to attach the secondary mirror to its stalk on mass produced reflectors.

If the OP's scope happens to have one but others do not, what is the problem? The manufacturer could have changed the attachment method in a certain year.

Mine was held on by a sticky pad
