Thanks everyone for all your help and advice. The two 6se's have cost a total of £300 so I've done OK, especially if I can sell some parts.

I've just bought a 6se on ebay with smashed corrector. Fortunately the secondary is OK as is the retaining ring. It cost £100 but everything else still works so I'm going to try and recoup my losses!

this confirms what i thought. I'm missing the ring that obviously secures the secondary in place. Is it possible to order such parts?

I meant corrector!

I've bought a very cheap 6se (cheap because the collector plate needs a good clean and one leg is missing its wing nut.) On close inspection today I noticed the secondary appeared to be a little loose. I carefully tightened it in its thread. I noticed an external thread around the outside of the internal thread I tightened the secondary into. Now I'm wondering if I'm missing a ring to secure the secondary in place? I'm also wondering if the collimation will be out as the secondary has been moved?

Off to Google astrohopper !

@RT65CB-SWLthanks for your help. I have been offered a 5 yr old 10" skywatcher skyliner px dob for £275 which seems a really good price? I must admit I would like goto/ tracking at some point in the future. Is it possible to add it to a dob or perhaps I should save for a flextube goto?

Thank you Mike. Really appreciate your advice.

I meant RT!

Thanks so much RC. I was attracted by the goto but did have doubts about the scope itself. At £350 I'll steer well clear! I guess it's back to a dob then.

Are you referring to goto in general or this scope in particular, Mike?

This scope is on sale and is described as a meade star navigator. I'm not sure. Also they don't know what size the mirror is. Any idea? Finally is it any good? TIA

Thanks for such a comprehensive answer, Vlaiv Really useful.
