Meade Lightbridge or Skywatcher
      #6060173 - 09/02/13 10:41 PM

Looking at getting a 10 or 12 dob. I am looking at the Lightbridge and the Sky watcher.
Which would you choose and why?
As a side note....Do the 10 inch Sky Watchers come with the bearing pads or Teflon pads?

Lightbridge without question, simply because of the focuser. The Skywatcher comes with a standard focuser but the Lightbridge has one with a 10:1 fine focus knob.

Our 10" uses Teflon pads but the 12" and large use needle bearings.

Thanks for the info. How well does the tef pads work compared to the bearings?

I cannot comment on these particular scopes but if you look around at the "premium" Dobsonians, Obsession, Starmaster, Tetter, etc, they seem to all use Ebony Star-Teflon or some slight variation for the bearings.

Bearings need to provide some resistance, some friction, so they do not overshoot, you want the scope to stop moving and stay there when you stop pulling/pushing.

This is true, and one of the few things I don't like about my Lightbridge. I find I need to clamp down hard on the center-screw on the groundboard so that the scope does not turn TOO easily. Otherwise if there is a breeze and you turn away to change EP's or something the scope can move by itself!

My 10" Lightbridge has the best movement of any dob I've ever used, by a long-shot! Balance is the key.

My 12" Meade Lightbridge is far ahead in terms of smooth motions than the Sky-Watcher dobs I've seen, but the best I've seen is still an Obsession. OK, so it was a 20" and it was 40 times as expensive, but I just wanted to mention it...

With my 9mm ES100, barlowed to 340x, I have no trouble whatsoever tracking any object anywhere in the sky with my 12" Meade, even the zenith.


Clear skies!

Custom Dobs (Obsession etc) have large altitude bearings and in my experience are just better at tracking. The other night I was observing the bright planetary NGC-6210 in Hercules with a 13.1 inch Starplitter, the altitude bearings have a 24 inch diameter. I was at 380x and wasn't seeing much detail so I Barlowed it to 760x. The motions weren't quite as perfect as the 25 inch Obsession, large scopes benefit from their mass, but I was easily placing the image where I wanted it in the field of view with a minimum of shake and jitter... I was happy.

Lightbridge is pretty easy to manuver, holds collimation well, pretty nice focuser too. I would go for them- definitly worth it

I've never personally tried either of these scopes, so I have no first hand experience, but I can tell you that a long time member of the local astronomy club has owned a Meade Lightbridge for as long as I've known him. For several years he owned a 10" Lightbridge, and eventually upgraded to a 12" Lightbridge. I've only heard him say good about that scope. I've seen him out in the field with the scope many a night, and he always seems to be having an absolute blast.

Thanks for sharing. I wonder why they don't put the 9*50 finder scope on the Light Bridge.

Ya the stock finder is pretty useless. I put my own 9x50 on it plus a Rigel Quikfinder. Rigel gets me in the neighborhood, 9x50 nails 'em down. Like shootin' fish in a barrel!

I have no problem with the stock red dot finder on my LB12. It gets me close enough and I use a RA 10x60 finder mounted next to it to zero in.

Will the Orion 9*50 fit the factory finder scope mount for this scope (Light Bridge)? I am thinking of ordering one for my XLT120 and it would be nice to use it on both.
