Just keep in mind a lot of experience and opinion is from many with focal ratios shorter than 10 and thats significant.

The original question was for a favorite high power eyepiece for planet observation in an f/10 scope. My favorite eyepiece for high-power planet viewing in my C6 f/10 SCT is a Pentax XO 5.1 - amazing as that may sound to some observers. :shrug:

The C6 is my only f/10 scope, but I do have scopes from f/4 to f/13.

I wasnt referring to you Mike. I trust your results as a rule actually. It is a n issue I've seen rear its head elsewhere enough to think it worthy of mentioning.

Cheers,

8mm and 11mm TV Plossls get my vote depending on seeing conditions.

In my C11 (F10) , with the usuall yukky seeing on most nights a17 mm tv plossl or 17 ethos is about all it can take but ocassionally when seeing permits , a 13 or 10 can be used , the 10 would give 280x.

Understood. I just wanted to underline the point that it wasn't me you were talking about.
