What about the Burgess TMB Planetaries that everyone over on CN seems to be buying? Long eye relief (16mm+) and 60 deg FOV for $US99 for the 9 & 4mm and $US49 for the early version 6mm. From all accounts (and there are many) they should be very good. You could get them from
www.highpointscientific.com. Postage is near $US70, but it seems to be the same no matter how much stuff you order, so if you order close to customs limit's worth, it is not bad. I just bought a binoviewer + EP from them and it got here in just over a week.
For high magnification planetary viewing I'm pretty happy with the barlowed 12mm HD ortho, which becomes a 5mm in my barlow (can go down to a 4mm with a barrel extension). Very comfortable with plenty of eye relief (with the barlow you get a bit more ER than using the EP alone), and the barlow is good enough to maintain the great contrast of this EP. You do need a good barlow for this; not a crummy Shorty Plus!
But wait there's more! I just received an older style tiny little 10.5mm TV Plossl from Chris (33South) and was looking at Saturn with it the other night. I compared it with the 9 & 12mm HD orthos, and the TV seemed to have the best contrast. The moons of Saturn stood out more clearly (esp. one very close to the planet) in the plossl than in either ortho. I'll have to do more testing to confirm this but I might have a new winner for contrast and maybe transmission too. Eye relief is not too bad, maybe a tad less than the 9mm ortho. I haven't tried it in the barlow yet but should be great at higher elevations in good seeing.
