Show Us Your Large Portable Telescopes

Recommended Posts

Show Us Your Large Portable Telescopes.....

Many of us are interested in large portable telescopes.  And just out of curiosity...what do you use to transport your large portable telescopes to your favorite observing site? 

Also...For those interested....here is one of the biggest standards to compare yours with when it comes to telescope portability....>

http://www.cruxis.com/scope/scope1070.htm

P.S.  For those interested...this is my humble homemade all-plywood portable 10-inch f/4 Newtonian called the "Dob Buster".  The 2nd. pic shows it disassembled ready for transport.  The 3rd. pic is my Pyrex 10-inch f/4 primary mirror and the optical box.  I hand-ground and polished it in the early 1960s and it's still in use today.  Once at my observing site...the total assembly time for the "Dob Buster" is about two or three minutes.  It was strictly a handmade with a saber saw, screwdriver, electric dril and sandpaper project including the 32mm 5-element camera lens PVC Erfle eyepiece and all-plywood magnetic base 40mm periscope style finder.....Note that there are four brass knobs on top of each corner of the primary mirror optical box and are used for collimation via black O-rings (5th. pic) and small wooden pulleys.  The 4th. brass knob locks the primary mirror in place. The bowling ball counter-weight is about 16 plus pounds.  Except for a used bowling ball, a few hardware store and some junk parts....there's hardly anything commercial on it.  Overall...being made almost entirely out of 1/4-inch plywood....it is a very light-weight Newtonian telescope to use,  carry, assemble and transport.

I would class this as transportable. Portable , to me, suggests being able to carry the telescope complete.    ?

Yeah...so would I.  Interesting enough...the website article gives the big 42-incher a "portable" label instead.  The 42-inch mirror alone takes about 4 men just to carry it.  Not very portable is it?  And probably the same could be said for this OMI 48-inch Dob too....>

Ha - now that is large! I've only a 15" tiddler compared to that 42" - that guy might call it a finder scope :)

 It goes into my car like this:post-34579-0-19788700-1439496739_thumb.jpg.0c7514359187a8132186b0c3c2bc9bbb.jpg.cfe8615b8fda6c4fd607696da584e61c.jpg

For size, here it is beside a 10" Skywatcher 250px:

Takes <10mins to assemble & collimate.

Very nice Dob setups.  They both Look like they are portable enough...that's for sure. 

I imagine the following cartoon link may be more common than we think...especially when you've just finished building a big Newtonian and you're trying to transport it to your favorite observing site for the first time...>

Here's my 12" OOUK Dob on a padded sack truck, acquired specifically for observing Mars in 2018 when I was going to be stuck in UK for the summer.  The mount and EPs go in a wheelbarrow.  I can get a 360 degree view from a hill about 400 metres across a road through our village.  Potential problem is the road is a main north-south road in busy south-east England (A29) and traffic hares through day and night.  A 79 year-old pushing a rocket launcher on a sack truck is an obstacle speedsters  don't expect to encounter.  I wear luminous bands and carry a white light forward and a red light behind, then I have to push the gear up the hill.  You guys stowing  your kit in cars - how portable is that?

Observing at our place in France is easier - just wheel it out of the barn on a flat home-made trolley.  That's where it's headed this Sunday to replace the 8" Dob already there.  Anybody want to buy a used sack truck?

This is my 14", about as portable as it is possible to get.

This one would take a pretty big truck to move this big 70-inch Dob down the road to an observing site.  Transportable or not....it certainly would be well worth a night's observing session to view the celestial sights with it....no matter where it's parked.....>

An excellent setup for portability...and a very splendid looking open truss Dob too.

For me, "portable" in the astronomical telescope sense means "can be carried in one go by one person".  There's a difference between that and "transportable" from my point of view.  A large "briefcase dob" or "rucksack dob" would fit my definition, even if it has to be assembled on-site.  A large cabin-baggage friendly suitcase dob would be a marvellous thing.  I don't think Stu is too far off that.

Of course others may have different definitions that they prefer :)

Got it in eventually! Only 16”,  But a truss design is looking very very tempting.

Good grief my eyesight is getting bad. I first saw that black windmill as a gigantic Dobsonian!

Must go to Specsavers! ?

? I had the same initial thought!

Then I thought how genius to set up in a spot as as to mask the moon ?

That said I'll still be converting mine to a truss system hopefully this year.

Can haul this out occasionally, transported to a dark sky location in a Nissan Note.

That  would be some suitcase, or are each of the struts sectional?     ?

With the Sumerian, yes, the truss poles come in two sections so would easily fit.

As you might imagine, pushing my contraption up a steepish cart track isn't something I want to do that often.  On this occasion the chap reconstructing the windmill was on site so I was able to show him Jupiter, Saturn and Mars in a different part of the sky before totally blowing his mind with the craters of the moon.  One of the few clear nights last summer.

Here is mine similar to Stu set up its the ultra light 14” Sumarian think it would fit in a smart car boot it’s that small footprint when disassembled takes only few minutes to erect
