Can you help me identify and item?

I'm not too sure what this is, it came with my 2003 skyliner any ideas?

*200p

It's the adapter for 2" eyepieces. You use it instead of the 1.25" one that is in the scope.

Yup. Have one just like it for my 150PDS. Mine also usefully has a thread for a t-ring.

[Lowen22]

I think this one also had a thread too. What's the advantage to 2" eyepieces?

A 2" eyepiece can deliver a 50% wider field of view than a 1.25" eyepiece of the same focal length.

I had something similar for my 250P but it was not the right size for. A friend of mine who has a lathe kindly modified it for me and it works beautifully. Not sure of the official difference between 2" and 1.25" is but I bought a Skywatcher 28mm (from memory I think it was £28) and the view was so immersive, gives a lovely view.

[Lowen22]

Thanks, maybe when I upgrade eyepieces I with take a look at some 2" ones.

It's a terrible picture because I can't seem to align my phone with the eyepiece that well... However it is Jupiter

If you Google Telescope phone bracket mount, there a some simple DIY suggestions to enable you to take pictures at the eye piece with your phone, commercial products are also to be had. Another tip for you, in time you may find that the rubber to the focusing wheels could begin to fail. The general feeling among some of the forum members, is that the Chinese don`t quite understand the production of quality rubber and steel. A good replacement, that will increase the diameter of the focusing wheel, which is a good thing for better fine focussing, is the use of a number of tight fitting rubber "O" rings, they look nice as well
