Hi all
Finally had a chance to do a comparison between
the TMB6mm and the TV Radian 6mm.
Just to clarify my vision is quite poor with astigmatism of 2.5.
Yet I prefer to view without glasses as I consistantly see more without them.
Tonights targets were an almost full moon and Jupiter.
Telescope TOA130 fl1000mm so 167X.
First thing I noticed was a greater sky darkness with the TMB, maybe the TV needs a clean. There was a nice moon off the limb of jupiter. Details were lovely with both EP's and my poor quality vision was unable to destinguish between the two. The field of view with the Radian was slightly larger I thought. The TMB seemed more contrasty. I preferred the Moons shadow creased limb with the softer Radian. Jovian details seemed easier to spot with the TMB. But it was all pretty much of a close call.
Conclusion: Very impressive for a $50- eyepiece, especially when compared with a quality Televue EP 5 times the cost. My poor vision couldn't tell them apart
With a couple of days hindsight I would like to add that the TMB seemed to be easier to focus well. The Radian produced a similiar quality image but was harder to fine tune. The Radian does have more bells and whistles with the adjusting collar and optional astigmatism compensation lens, but I've never bothered with that. I still find that with my poor vision I usually out perform the casual observer due to my many years as an amateur astronomer. You kinda learn how to look to max what you see.
Clear Skies
