Filters helios apollo 15x70

[John88]

Hi all, 

 

I have just bought some skywatcher filters (uhc and o-iii) to use with my helios apollo 15x70 

 

But I can't seem to screw them into where the eyepieces are, I must be doing something wrong but thought it should be fairly easy to fit. 

 

Have added some pics just incase there is a model which can't accept them or something 

 

Many Thanks in advance

This is very weird.... It almost seems as if they have begun designing the apollos without a filter thread. I answered a question similar to yours a while ago

Thanks for the reply.

That's a shame looks like I might be sending the filters back, I got the bins second hand so can't look at exchanging them

They can be specified with or without filter threads; worth asking before you buy. I think some of the Delta Optical (similar, but ED glass) may have filter threads.

Definitely something to keep in mind in the future great bins though

 

Have done a bit of a bodge solution by putting a rubber washer round the thread of the filter and they are now push fit. Given them a good shake upside down and seem pritty solid although they sit a bit proud.
