Thx guys for the feedback. As it happens I have a vixen eyepiece (20mm) and was wondering why it seems to have such a narrow field of view compared to my other EP's. Turns out it only has a 50 deg FOV and as such gets less use than the H20 which I'm finding is giving a good crisp view despite what is oft said re these EP's around the place. I now understand why some don't like that narrow FOV. I did see another possible way for this, e.g. just like there are filterwheels for the cams it appears the are eyepiece wheels which would give the same basic functionality but with whater EP's you have at hand.One such on ebay is

I can even see something like this making my imaging a lil easier, e.g. 20mm in one adapter, 12.5 in the next, cam in the 3rd. Initial aligment with the 20, swap to the 12.5 and recenter, swap to the cam. All without removing anything. I'm still deciding but will likely give the whell a go me thinx
