glee, too many roots? Stones in the yard? Larger wheels can handle much of that!

Wouldn't it be better to view with a larger scope?!

I do know what you mean about trips and motions; it would get tiring if one had to keep taking the OTA off and on many times per session.

A larger scope always gives better views, but a 6"f8 is about the largest that I can easily manage on this rural observing site, which is very dark in addition to being on a steep, forested slope littered with leaves, pine needles, roots, stumps, fallen branches and large rocks.

On more benign sites, i have wheeled telescopes successfully, but terrain here is too rough for wheels and telescopes.I do use two-wheel carts with large diameter wheels here in daylight for moving debris and building materials that aren't damaged when the carts flip from time to time, but a TS would soon be trashed. So far, adding functional handles to both sides of a 34# 6"f8 is the best solution that i found for this site.

I tried a stock 41#, 8" f6 (XT8) here for a year before giving up on it and going to the 6". At the moment, i am trying to decide whether to sell the XT8 or have a Baltic Birch base built to reduce its weight, adding handles to make it easier to man handle, and giving it another try.

Ouch! You are in difficult terrain! Even moving the scope as one unit sounds like a challenge! Stumble over a root or stump and you and the scope could go tumbling!

How much weight would a Baltic birch base save?! Given the dark skies, it could be that a Baltic birch base for the 6" could be an even better solution!

I do wish someone would make a 6" f/8 dob with a mount that weighed only about 10-12 pounds! I'd buy one in a heartbeat! The combination of a tube that weighed only around 11-13 pounds and a mount that light or lighter would be great! Good depth of focus, forgiving of low-end eyepieces, easy on the collimation, and enough aperture to start brining out DSOs.

Right now, though, all those 6" dobs come with 8" weight mounts -- 20-28 pounds!

I believe a baltic birch base would save about 5#. I am not sure how stability would be effected though, which, so far, has kept me from ordering one. My experience with a very lightweight, but shaky, 8"f6 Portaball has made me cautious about going too light.

I have given up on the XT8 and put it on Craig's List and plan to continue using the stock XT6i here until i find something that works better. At 34#, it's light enough and the addition of handles on both sides of the base make much easier to hand carry, and I am satisfied with its optical performance.

It's weak link now is the stock focuser, which is just adequate after some tuning, but it really needs to be a 2-speed to cut down on the shakes while focusing, but that would add weight and might introduce balance problems, so i am not rushing into it.

Hi,

I have my 10 inch dob on a yard cart, purchased from Sears.
I got this from their "return" section and got if for 55.00 because the box was heavily damaged.

Anyhow, though not a panacea, it allows me to move the scope several hundred feet. Which comes in handy, to move it to a park close to me,
and when observing where I put the scope in my car, and have several hundred feet to move it to the final location. The pneumatic large tires, means
I can off-road the scope, if I am really carefull and the ground is only moderately bumpy.

You can observe from it right from the cart. But I have to say that the pneumatic tires make it more bouncy.  The eyepiece height is about 65 inches
from the ground if the scope is pointed at the zenith.  I only do this when observing in an area with lots of trees where I know I am going to have to
move the scope several times during the night. Otherwise I unload it from the cart for more stability. The cart also makes a nice table.Attached Thumbnails

Skyquest xt8. End of story.
