Dearest Solar Friends

I was sold this by an unscrupulous
astronomer and am now required to
repair the item ... any help advice
would be greatly appreciated
It is obviously a rusty ITF

Hello Brian, You can obtain a new ITF filter, which is a straight swop, from Maier Photonics inc, in the USA, mine cost about £55 delivered. Might be slightly different because of exchange rates. This will transform your scope to as good as new.
Hope this might help,
John.

Hi Brian ,The tube that screws into the body has to be removed, VERY tight usually, but a boa strap may help. When removed you will find a glued ring with 2 holes which has to be removed,use a pin punch with care, then remove old ITF and replace with the new one.
Hope this help, John.

Hello John
I now have the new ITF ... in the
image you can just make out one
of the hole impressions I think you
refer to ... do I have to apply a lot
of pressure to them to release the
existing ITF.

Hi Brian, The two holes,which you should unscrew ,using a pair of strong dividers,the locking glue is very tight to undo. When you remove the old filter try and make sure you put the new one the same way up. John.
