DIY 2" Filter Attachment for Newtonian

Postby lizd31 » Thu Mar 18, 2010 2:10 pm

Hi Guys

I am now able to attach a 2" LPF (or any other 2" fillter) to my 250Px for observing and imaging purpose.
I have araldited a 52mm-48mm stepper ring (thanks geppetto) to the rear face of the 1.25" eyepiece adaptor.

The 2" LPF (thanks little Col) simplt screws into the stepper ring thread.

Luckily, the O/D of thr stepper ring and 2" filter is less than the O/D of the flared flange of the eyepiece adaptor so no problems in that respect

cheers

Graham
