Thanks John! I do very much like my two Elites. I must be getting old because I can't be bothered with bulky and heavy wide-field EPs any more. I find a 60 deg AFOV plenty. The Pentax XF 8.5mm serves me well there. And given their great performance and convenient size and weight, even at "just" 50-degrees the Elites are a pleasure to use.
The other similar EP I have is not an Ultima (like I incorrectly stated earlier) but an Orion Ultrascopic 35mm. It's pushing the exit pupil for me a bit in an f/4.9 but it's a nice TFOV regardless and in the old f/10 Intes Mak (which only has a 1.25" focusser), it's just what the doctor ordered.
I'll give the Parks Gold Series + Antares Elite pair-up a go. Main reason I am asking about the GS and not the other similar line-ups is that AEC have the 25mm and 15mm for very decent prices (esp. considering the poor $AU-$US exchange rate atm) and I happen to have the Elites in the same focal lengths. (I must say I hate the name "Elite" but you know, whatever ...
