1) Pentax XL ( best throughput and image detail on Jupiter)
2) Radian (very close second I might add)
3) BO TMB ( because of FOV and eye relief)
4) UO HD, Circle-T Ortho (due to eye relief and FOV)
5) Nagler T-6 (rating reflected the amount of aberrations)


So, the TMB keeps good company for the price if you can find a good copy, range from $50 posted but not always good QC unfortunately.

Thanks Steve. Some good stuff in there although it's a few years old now so there are other players in the market these days.
