Forgive me if this has already been suggested Andrew, or you might have thought of it yourself, but could you not gain that distance by releasing the mirror up the tube. There must be at least 15mm leeway on the adjusters to allow you to send it towards the secondary a sufficient amount.

I've got it up as high as it'll go. But I could put longer locking bolts on I suppose...

For who? What do you need to do this kind of thing?

I could do it in a few mins on the lathe in the "workshop" - try and find an engineering "jobbing" shop if not its a few hours with 120 grit paper and a piece of glass...

Andrew, why not drill three different holes in the tube to enable you to move the mirror up about an inch.

It is not a difficult job to do. Put some masking tape longitudinally along the three existing holes, and mark the distance you want to move the mirror. This after removing the cell of course.

Once you have marked the positions. drill the holes with a pilot drill first, about 1 millimetre, then working up to the size required. Refit the cell, and re collimate. I would use a hand drill to do the job, less chance of slipping.

Just an update - I have solved the problem

Put the low profile focuser from my 8" on the 16" and the standard Meade focuser on the 8" - the eyepiece now comes to focus on both scopes.

So does the DSLR on the 8". :hello1:

There you go. Proof indeed that two Pennyworth of thought, can save hours of work.

Good thinking young Andrew. Jobs a good un.
