Yes groan old chestnut. Have read Astrobaby guide and watched youtube.

I understand that if a fast scope the secondary mirror in the middle is offset nearest to the leg. Also the tiny dot in the tiny dot is in the middle but moves a bit depending on each tube extension I find.

But should the bigger image of the secondary mirror be centred around the primary mirror or is this again offset in a faster scope mine being f5 please?

Looks about right, but your primary mirror is off slightly.

[happy-kat]

In what way is it off please as the clips are all visible equally?

Is it that the large shiny disc should be centred in the black disc (regardless of speed of scope)?

[Naemeth]

The secondary is fine (as seen by the three clips being shown), the primary is aligned when the circle and black disk are aligned, you can see it's slightly off in the picture. These two should always be aligned regardless of the speed of the scope.
