TEC 180 on Losmandy G-11
Posted 23 February 2013 - 06:16 PM
Some specifications... The TEC 180 will probably weigh around 42 to 44 pounds with all visual accessories attached. The capacity of the G-11 is 60 pounds plus balance weights. The TEC 180 is 45 inches long with dew shield retracted, and around 54 inches long with the dew shield extended.

Just after ordering my AP175, I spoke to Scott at HGM about using my G11 with it. He said that the G11 would handle the scope in a zero wind condition but that he would not advise using it. It's not the weight but the moment arm that the scope creates. I opted to sell my G11 and move into the Titan. I would rather spend a few extra dollars than risk any issues with the scope.

I can use my scope on the G-11 in light breezes, up to about 5 MPH, but building a pointing model is hard because with a moment arm that long the scope does move around some. The biggest problem really is that moment arm. Changing from a Radian or Nagler T6 to a Nagler T4 creates balance issues. I've changed my RA motor to a Maxon to relieve some intermittent troubles I started having last year.
One problem you might have is motors stalling when slewing. If that happens, try slowing the slew speed down. A friend just bought a 6" f/15 that he mounted on his G-11. He had to drop his slew speed down to 600 to get the motors to stop stalling.

Has anyone ever mounted a TEC 180 on a Losmandy G-11 mount attached to a Berlebach Planet tripod? I already own the G-11/Berlebach.
I have no experience with the 180, but I do own a TEC160FL and use the Berlebach Planet/G11 combination often as my "quick-look" setup if there is a such a thing with a a 6" refractor. And, while its OK - I much prefer using the G11 on top my 8" ATS portable pier.
I do not think you would be happy with the G11 on the BerleBach Planet. I think If you have to use a G11, its probably best to use it with the stock G11 tripod (if available to you), which is incredibly sturdy.
But at the end of the day this OTA - TEC180FL - is really more comfortable riding on an AP900 class mount.
Below is a pic with my 160 on the G11/Berlebach combo. I have since purchased the larger tripod shelf/spreader so the spread of the three legs is a bit wider.
