Thats not a problem for me tony as my lunar observing consists of wishing it would bugger off so the sky gets dark again...
I went and ordered one today from japan .. couldn't find the xf line here in oz ..after I ordererd I noticed bintel stock them
..I wasn't aware they stocked pentax eyepieces and the price was very similar.
anyway i"ll pass on my thoughts when I get it .
thanks for all the input
