When it comes to dobs, the weight isn't as troublesome as the volume. When I was a couple years younger than you are, I had some trouble carrying the OTA of my 6" dob from my bedroom to the front yard, only because it barely fit between my little arms.

And then, one night, tragedy struck: I smashed it into the door frame, and my primary mirror cracked. From then on, everything I saw through my telescope had a ghostly double image. It would be about 10 years before I could afford another telescope.

So: yes you'll be able to handle an 8" dob (and you'll only get bigger and stronger, remember), but be careful!

The saddest story EVER.  Well OK, not refugees sinking into the ocean sad, but getting down on the list.

At age 12, my 5' tall self was carrying a 4.25" aluminum-tubed reflector, with german equatorial mount on a heavy pipe pier, completely assembled,
2 or 3 houses down the street to a vacant lot. It weighed more than a 6" dob, but probably not heavier than a complete 8" dob.
Carrying the scope to the backyard in 2 pieces, base and tube separately, should be a cinch for you.
Just be very careful around stairs!

Why carry it? Put it on a cart or a hand truck of some kind.

My 8" Doblives in the garage. I don't carry it I roll it. Then I lift it off the cart at the observation site. Can be lifted offas two pieces if you like.

A 6" dob is about the weight of 2 16 pound bowling balls. An 8" Dob, about the weight of 3.

Unless the 14 year old is a 98 pound weakling, then yes, of course. Any healthy 14 year old should easily be able to handle 50 pounds or more, depending upon whether they just sit and play video games, or actually live.

..Joe

That is a rather inappropriate/ill consideredthing to say to someone who is still growing. I amguessing you have never been toAsia or the Philippines. While in the US obesity is a problem at an early age, it is not that way everywhere or even for some American kids, including my son or myself when I was that age. I didn't weigh 100 pounds until my growth spurt around my 15th birthday...and my son has followed the same pattern although a little taller to start with and about 5 more pounds on him. I was a farm kid so I did plenty of heavy lifting despite my small size at the time. Kids raised in urban/suburban homes are less likely to get as much opportunity to lug around heavy objects.

And that is without even considering females who on average are smaller. So I wouldn't call kids who very well might not have hit their growth spurt and are at far healthier BMI's than our own average youth "98 pound weaklings."

Handling half or more of one's body weight "easily" is a dubious proposition when it is a bulky deadlift.

As has been noted, the 6 and 8" Dobs get around this by being portable in two sections of weights more appropriate for kids of various weights and sizes.

After the discussion here:https://www.cloudyni...on-skyquest-45/

One person told me to get a bigger telescope than two of the scopes I listed in that thread, specifically an 8-inch dobsonian.
I found out that the person was a year younger than me, yet he can carry an 8-inch scope.

The reason I'm asking this is because I'm generally not that strong. That's why one of my biggest worries when buying a telescope is whether or not I could carry it. (One thing I know though, is I can carry my cpu tower with parts.)

So, can a 14 year old carry a 8 if not, 6-inch dob?
I think the better question is whether a 14 year old would want to have to lift and move a 6 or 8 inch full size Dobsonian. Unless you can move it on a cart, as I show in my photo, I would say the answer is no.Looking at the other discussion I think you make a very good case for why you would like to consider the skyquest 4.5 full size Dobsonian or a tabletop Dobsonian telescope like the AWB which has a 130 mm aperture.

This is especially true if you will have to carry it on a bus at times. I am a big man and I would not want to take a 6" or 8" full size dobsonian on a bus.

Remember, in addition to the telescope you still need to carry your accessories as well as some sort of chair or stool.

I copy in your first post from the other thread.

I'm back after a long time of inactivity!

So, I'm really lost about which telescope to buy. (Dang it, INTP)
I started about a year ago, when I wanted to buy some of Celestron's Powerseeker models. After a bit of research, I found that the mounts were wobbly, and I didn't want that.
I then decided on getting an Orion Spaceprobe 3 because I didn't have budget to buy bigger scopes I wanted.
Then, I also found out that also had slightly wobbly mounts and the eyepieces were mediocre. I wanted a better, bigger scope but portable and inexpensive.
So I'm still deciding on two telescopes:
The AWB Onesky or the Skyquest 4.5.

I know that while the AWB Onesky has better light-gathering abilities, the Skyquest 4.5 has better optics and longer focal length.
So, which is the better telescope?Some things to note:
- I don't want to carry things heavier than my CPU.
- I'm short (4'10).
- Maximum budget is about $350.

The only negative to a table top designs is that they require a table, box or other place to put them to be at a comfortable working height. If you have that conveniently available then they can be VERY good upgrades from a 76 mm Spaceprobe.

The 4.5 inch/114 mm XT4.5 Skyquest (900 mm FL) will gather 2.25X the light of your 76 mm Spaceprobe. That is a significant upgrade.   If you are going to use it primarily at home, this is a very good choice. At 18 pounds you should easily manage it in one trip.  And you can put it on a cart or a small hand truck to make it even easier to move it.

If it is available in your country I would recommend this package. It includes two good eyepieces and a 2X barlow which will take you to 180X without having to buy more eyepieces. The eyepieces from your Spaceprobe will work with this scope to take them into consideration too.
http://www.telescope...s?keyword=XT4.5The 130 mm AWB (650 mm FL) will gather almost 3X the light of the Space probe. This would be a better choice if you will have to transport the telescope on public transportation. You can put this in a large backpack, along with eyepieces and other accessories, due to its collapsing design. You just need a stable place to use it.
https://www.astronom...&products_id=4

Again the eyepieces from your SpaceProbe 3 should work with this telescope too. You will want to get a barlow for this telescope. Considering the 650 mm FL a 2X barlow would work but I would probably recommend a 3X barlow. I have an 80 mm/400 mm FL refractor and I use it with a 3X barlow for planets.  The included eyepieces combined with a 3X barlow would give you 196X.The larger aperture of 6" or 8" full size Dobsonian is great for observing but if it is too much work to move it and set it up, you won't use it.  If it takes two or three trips to set up that means 2-3 trips to put it away too.  Then that larger aperture is not helpful at all.

Remember, after you have made 2 trips to move the 8" telescope then you need to go back and get your eyepieces and other accessories. And then you need a chair of some sort.Considering your situation and your plan I think you have picked two very good options in the Skyquest 4.5 or the AWB.  Either will achieve 200X or higher with the right combination of eyepieces and barlows. And remember that the atmosphere is often the limiting factor for how much magnification you can use. Even with my 8" Dobsonian 200X is often the highest I can use.I don't know what costs are in your country and what is readily available but either of these scopes would serve you well.

In 1976 I got my first telescope is Edmund 6 inch reflector and metal mount. I was 15 years old and take telescope out two trips to get up telescope and mount. I had 10 inch dobsonian and take two trips (telescope and base) to backyard is NO problem!

I actually changed my mind on getting the small scopes because if I would go to a dark site (my grandparent's home), I could stay there for several nights because it would be so far away (5 or 10 hrs, depending on which site) I actually have an idea how to pack a 6 or 8 inch dobsonian in a bus:

1. I would put the base in a box, then put it at the trunk of the bus (most buses in my country allow people to store bigger stuff there)
2. Then I would put the tube and eyepieces at a bag with padding. I would bring it inside with me.

One question: What bag can I put the tube of example... Orion XT8? And what padding should I put?

Note: I have family members who can help me bring my scope

I'm 14, and while I don't own an 8" Dob myself I've borrowed one and moved it on my own with no problems.

You're 14 AND a vendor?!? How did that happen? What do you sell? STARKID2U

axl 2468 , Orion sells all kinds of padded bags specifically meant for their telescopes . One could probably buy a bag from a sporting goods store to carry bats/baseball and pad it out also. Where theres a will theres a way ! Under accessories at www.telescope.com

Judging from the website, probably a family business. (If so, I'm so jealous right now)

I didn't know Orion had padded bags. Thanks for pointing it out!

Has anyone used one of Orion's padded cases before? Are they well-padded enough for transport in a bus or will I need to add more padding?

Do you know any sleeping bags of perfect size for an orion xt8 at amazon? I checked at an online store in my country and all were too small.

Well, the Orion XT8's optical tube length is 46.5" (per the Specifications on http://www.telescope...pe/p/102005.uts ). Say that the 8" scope has a tube Outside Diameter (O.D.) of 10" -- that would give it a circumference of 31.4".A sleeping bag (like this one on Amazon https://www.amazon.c...eping bag&amp;psc=1 ) measures 33" x 75", so it would be big enough to cushion the tube.
