Which refractor?

I am considering the following APO's for planetary use. Just wanted some input.

Tak FS102
Tak FS106
Meade 127ED (how's the color correction?)
Televue TV102
Vixen ED114SS

Of course these are all new, I am also looking at the used stuff. Right now I am leaning twords the TAK FS102. Is there anything else I should be looking at in that price range? ($3000 or less for OTA). Which of the scopes above have the best color correction and which has the sharpest image (and hold up under the highest magnifacation given ideal seeing conditions)?

Thanx

Oh boy, here we go! For planetary and best color correction, that would be the Tak FSQ106 Petzval with Extender Q; it also doubles as the best astrograph. A similar choice would be the NP-101 but it does not have the Q's wider/stronger focuser. My opinionated ranking:

1. Tak FSQ106 w/Extender Q (or NP-101 or TMB 105)
2. Tak FS102 tied with TV102
3. Meade 127ED (more aperture, but semi apo)
4. Vixen ED114SS (Petzval with color?)

There are other planetary choices for $3000, but you wanted apo refractors.

How about something completely different?

A 6.5" unobstructed, perfectly color corrected telescope. If you get the OTA, you have $500 left over to go towards a binoviewer. That's my dream planetary setup.

I had a Meade 127ED color correction on mine was excellent. I could push it to 60X per inch on good nights. See my review on cloudy nights. I believe you you would be happier with a 150ed.You would have a nice 6" scope. The Larger scope would need at least a eq 6 mount to handle. Even a synta 6" with a properly fitted chromacorector would cost around $1100 and offer you very good images. You can get more power and higher resolution. The larger aperture always comes in handy. See Yahoo meade refractor group for more comments.I am presently using a 7" Meade mak. You might consider one. Optics are execellent. I used it this morning on Mars under hazy skies. Even though it had not completely cooled the images were excellent and refractor like. It did compare with my Meade 127ed. An it does have 7" of aperture. On the moon it blows the meade out of the water, absolutely no comparison and it does take lots of power when condition are right. A used one would cost you around $1500. Only con, it's heavy and needs to cool down. Your choice.
