Using a filter with 13mm Ethos
Hi guys,
Was very excited to get a big parcel in the mail the other day - my astronomy Christmas came early this year! Anyway amongst all the goodies were a 13mm Ethos eyepiece and a 2" Orion moon filter.
Now I may be missing something here (entirely possible!) but there doesn't appear to be any way to connect the filter to the eyepiece. The filter has threading but the eyepiece doesn't seem to.
Is anyone able to confirm whether these two bits of kit can be used together?
Cheers!
