I use a 14mm Radian (135X) and with barlow (270X) for planetary and lunar work. great views.

I wish I could get that high a magnification. Living in town with all the heat off roads and house tops, the best I can usualy do is use my 13mm Nagler for 146x. Any magnification above that is usually nothing but a blur. Usually the air coming from the west over the Blue Ridge Mountains is just rolling and that holds magnification down too. I also find a barlow with this scope is useless except with lower magnification eyepieces. But I only use the 13mm Nagler(146x), the 19mm Panoptic(100x)and 24mm Panoptic (79x). The dew shield is a must have and I use a 1" extension tube from Lumicon, to raise the eyepiece, so I don't bump my head on the telescope when observing. I also use the flex cable and a clothes pin for fine focus. Clear skies, Buddy

Someone mentioned a focal reducer. At almost 2000mm FL, low power can be difficult to achieve, I would imagine. What FLs work well with the ETX125 and is there any vignetting?

What would be the 6 must have lens,barlow,or zoom lens for this telescope ??

1. 32mm Plossl
2. ~20mm 65-70° Wide Field
3. ~15mm 65-70° Wide Field
4. ~15mm Plossl or Ortho
5. ~10-12mm Plossl or Ortho

The wide field EPs I use with my ETX-125 are Zhumell, made in China, very similar to those offered by UO. I find, with the f/15 of the ETX-125, that these work very nice. I use these EPS almost every time I take out the scope. I have tried some Meade 5000 UWA & some T1 Naglers, but I think these are a little heavy for the ETX. As for the Plossls or Orthos, I have used TV, Meade 3000s, Faworski, UO Orthos; they all work nicely in the ETX for lunar and planetary viewing. I have many other EPs, but these are the ones I use 90% of the time with the ETX and I am very satisified.

--------------------


• Celestron Ultima 8, f/10
• Meade ETX-125/AT, f/15
• WO ZenithStar 66 SD APO, f/5.9
• Zeiss 50/540 ATM Refractor, f/10.8
• Bunch of Plossls, a few Orthos, some SWA & UWA...

I finaly got a realy good night of seeing tonight and was able to go up to 214x with a 7mm planetary eyepiece on my ETX125PE. This was the first time in over a year and a half that I was able to use that much magnification.
