GS 16" Dobsonian

[prova]

just interested to see if anyone is going to seriously look at purchasing one of these baby's when they're released on the local market?

[rmcpb]

Let's see the final design, price and delivery before we get too carried away. It will be interesting against the Lightbridge though.

My last understanding was that tailwag has one on order? But I haven't heard from him lately.

16" solid tube?
that would be nice :)

Still like to see the final design before ordering......

[monoxide]

im still pretty happy with my 12" though, thats around the maximum i can see myself lugging around the back yard

however if i had an observatory out in the sticks id be very interested :)
be interesting to know how much the tube weighs

[rmcpb]

Now that is sensible. In the world where we want the biggest and best often we get brainwashed into wanting the latest and "best". If a 12" does it for your then forget the larger one with its attached problems. However, it your are into deep sky objects heavily then the 16" will blow away the 12".

Anyone found pics of this toy?

[monoxide]

its easy to get caught up in aperture fever but for the price of the 16" you could get a 12" + the almighty argo navis

love the idea of the 16" solid tube though!
whos going to be the first to put one on a gem? lol

[Jarrod]

i found this site when i did an image search on google, but im not sure it is really a 16". by measuring the 50mm finder scope in the picture the tube is about 45cm in diameter, but then agian thats about the same size as the tube on the 12".

Good ideas, sometimes portability is not the best solution :) You may want ease of use and stablility!!

My 8" on steroids!

Doesn't seem to be any more substantial support for the 16" mirror. Everything looks just like my 8" expanded. I look forward to hearing firstlight reports.

Edit: Yes, Greg and Jarrod make sense - they've thrown in closeups of an 8" GSO dob.

[taminga16]

Check the scale in relation to the cooling fan? and the focuser does not appear to be 10:1, maybe they are starved for photos'.

[Jarrod]

the mount/base in one of the pictures is of an 8" GSO dob, and apart from the main picture (white tube) all the telescope tubes are the shiny brown/silver colour used on the 6, 8, 10 and 12" GSO scopes. it looks like GSO has emailed that one picture to all the distributers that have ordered a few 16"ers, and this particullar store is also using pictures of other GSO dobs just to display the main features.

OK, which is it? Early ot late? This is copy/pasted straight from the site :lol:

"NEW! 16" Super deluxe version Dobsonian shipment due late early Oct.

Only...A$2399.00"


:shrug:

[Jarrod]

:lol:

mmm, easier then writing "shipment due mid Oct."? :P

[h0ughy]

imagine mounting that on like a titan mount or similar?

[glenc]

It used to say late Sept, early Oct.

[CoombellKid]

I like how it say 'premium' in front of the ep's that come with it. :lol:

ok hear is 1 for u all help plz a 16:inch dob with f/4.5 all a 12"casseggrain with f/12 , will i see images i see on this page with the 16"inch better than the 12inch, what would u go , and how far will i see with each scope thanks for help

[sejanus]

^^^^^ best post ever

[glenc]

Malmsteen the 16" collects nearly 80% more light, compared to a 12", and so it is better for visual observing. The 12" SCT with a drive would be better for imaging. You also need to look at weight, cost etc. How far can you see? Here is a sample.

[Malmsteen]

ok thanks mate i am a ozzzy by the way that link was cool ,
so as far as the 16inch with a F/4.5
would go and the cassegrain 12inch with f/12
what do u feel would out do the other , will that look as far all clear , as the 16inch , becouse of the f12/ being a greater focaler ?? thanks for u help ,

[Domol]

malmsteen
basically aperture size relates to amount of light collected. bigger is better!
F ratio determines your field view with a given eyepiece
I hope i haven't confused you.:)

[glenc]

You can see further with the 16" but the 12" f/12 is good for looking at planets and double stars. However if you want something portable go for a 10" f/5 Dobsonian.

[Jarrod]

No mention of the 16" GSO on the 'Andrew's Communications' website.

http://www.andrewscom.com.au/site-section-10.htm

interesting.

It has however been mentioned in their magazine adds over the last couple of months. Perhaps Lee is waiting until he has some actual images, etc, before he puts too much on the website.

We've been hearing about these scopes for 2 years now I think, and even when the 16" Lightbridges were finally announced and orders taken it still took a little while for stock to arrive. When GSO's own 16" version finally arrives I'm sure Lee will have all the blurb available for us.

[MortonH]

Andrews has a sketch of the new 16" in the shop. In the picture it's a truss tube, not solid tube. Unlike the Lightbridges, it has three struts, each of which are basically steel tripod legs.

[Gargoyle_Steve]

That's interesting because ages ago the scuttleutt was all about GSO's own version being a truss tube dob exactly as you described, and speculation about how rigid that kind of construction would be.

Somewhere along the way then the talk changed and a solid tube OTA was being mooted, possibly this confusion was helped by the stand-in image on GSO's website.

Must say I'm more than a little interested to see how this unit looks and performs.

[h0ughy]

well that notice has now gone - zip nothing in its place:shrug:

Looks like its a no show for this christmas:sadeyes:

[davidpretorius]

what the hell is going on???

oh well santa will have to rain check it for me

[prova]

anyone know any further details on this baby?

[h0ughy]

nothing this year anyway.....3rd year waiting

[erick]

After looking a 16" lightbridge up and down, I can only conclude that a rigid 16" OTA is going to be a relative monster, not something to carry on the back seat of the car?
