I have an Explore Scientific First Light 10" tube dobsonian on backorder, since about August 19th. One of these boys:

We're coming up on 60 days back-ordered, so I'm wondering if I should just pony up to the 10" generation 2 truss dobsonian model, which isn't out of stock:

I've tossed around the pros and cons in my mind, and honestly, I could live with either, but I want to ask the forum hive-mind for its thoughts on this.

 

So come at me, bros. Give me your thoughts. And thanks in advance.

I'd rather have the tube Dob. In fact there are several tube Dobs I'd rather have than that 10" ES truss Dob, definitely including the Orion XT.

Ahh, but why, havasman? Not the Orion -- that wasn't the question. Why the preference for the ES 10" tube over the ES 10" truss?

Some of the pros of the ES 10" tube:

 

- Quicker to set up than the truss

- Holds collimation longer

- Lighter (to carry) components

- Lens included

- Adjustable OTA within the mounting rings (put the focuser where you like)

Some of the pros of the ES 10" truss dob:

 

- Dual speed focuser

- Fans for the primary

- Stores/transports smaller

- Front collimation

You could build your own. The materials, shipping, and coating would come out to the same price. Time to your door vs time figuring, who knows. Modern dobsonians are incorporating more and more of the features we want. Almost don't have to go custom.

You forgot - points to zenith without adj’ing 

a lot better materials - more sturdy - last longer

I'm looking at one of the tube version as well and will probably order one fairly soon mainly because it has rings and can be readily moved to an equatorial mount for imaging. Apart from that, probably the truss is a better purely visual scope if you never plan to remount it.

I was recording Scot Roberts putting a tube base together at NEAF and the hardware fell out of the particle board...bad enough I decided not to post it on my youtube channel.

the truss is way better made

After pondering it, I upgraded to the truss dob. I decided the dual-speed focuser and the compact storage possibility meant a lot to me. Explore Scientific was very nice about it, and allowed me to roll back time to my initial order date and get the pricing that was in effect then, even the first time buyer discount. Very considerate of 'em.

 

Hopefully I can cram a Telrad onto the UTA. I have one standing by.

Mmmmmm, I dunno stargazer. When I first considered this, I looked around at material costs and such. Seemed to me I could easily spend more constructing a nice dob than the price of buying one. And that doesn't even figure how much time I'd have to invest -- which is in short supply right now.

 

Am I wrong? You wanna break down what you think the build costs would be?

I have a 10" truss tube dobsonian and 95% of the time I wouldn't care if it were a truss or solid tube.  I keep it set up in the garage ready to go, and even if I drive somewhere, I usually load it up in two pieces instead of dismantling it.  However, we sometimes do family vacations and are usually packed to the gills, so at those times being able to it break down is a huge advantage.

If you can glue and screw I could hook ya up with cut parts

The 10 inch dob is just a no frills design, off the shelf fasteners to put it together, for what its worth all the collimation screws are thumbscrews, the ota is sort of heavy but the big altitude wheels makes it both easy (they are a handle) and hard (slightly awkward) to carry at the same time and having the focuser where you want it is super convenient.

The 10" truss dob is headed my way by FedEx. Should arrive Friday 10/19. I'll do an unboxing in a new thread. Unboxing threads are always fun.

I think you made a fine choice getting the truss Dob. I keep my 10 inch truss set up in the family room and carry it out assembled in two pieces all the time. Your OTA may be a bit heavy to manage like that, but you can get a hand cart if you want to take it out all at once. The ability to break it down for travel or storage can mean the difference of having an extra passenger or two go with you, or a bunch more gear, or having closet space in the house for more telescopes and stuff in the future. I believe you will discover the views in the 10 to be quite enjoyable and satisfying.

 

Best of luck with your new scope,

Don

I own the tube 10 inch. It is worth waiting for. Maybe out of stock due to demand exceeding supply.

 

The tube model can be slid through its rings to help with balancing, and can be removed for putting on another mount. Good rockers, none of the structural frailty of a truss, or any issues of ES truss scopes posted about in other threads.

Looks like telescopes.net added a decent finder scope to their kit. Explains the $595 price. ES has it priced at $459 but with a red dot finder.

Buying telescope parts would cost more than a telescope. Buying raw materials to make the parts would cost less for the same quality and the same price as particle board scopes. The labor would be a lot more. I would do it for the fun of building and having my scope just how I want it.

Whoa. Hope my experience is a better one.

I want to say a little more about this: it seems to me that one of the effects of the internet is that when something goes wrong with a product, we hear about that a lot more. The internet has given a voice, a very effective voice, to the customer in such situations.

 

This is a good thing, I believe. A power shift in the direction of consumers.

 

But the other side of this is that, it seems to me, we don't hear as much about when everything goes right, and the customer is completely satisfied. It's one of the reasons that I try to give a thumbs up to good service when it happens.

 

So, I know there have been some negative experiences with the ES truss dobs. I'm not sure we're hearing as much about the positive experiences.

 

I'll let you all know how my particular experience goes today, so that we have another data point.

An interesting idea, but not a project I want to take on just now. Nice to see Pinbout could source parts. Perhaps in a couple of years.

 

I just finished getting a motorcycle back on the road after tearing apart its driveline to fix some stripped clutch splines. Read about it here if you're interested. It was epic: http://forums.pelica...line-issue.html

 

Anyway, don't have the time and space for another maker project right now.

To me the truss seems only logical, when a solid tube version is available, if the truss solves storage, transport or handling issues.

 

A 10 inch F5 tube will fit in most cars across the back seat, or end to end on the passenger side. For 12+ inch a truss will have advantages.
