Little?
What's your other one?
Probably this one. https://en.wikipedia.org/wiki/Gran_Telescopio_Canarias
Which one is that!
Does not need to be a closed tube, very good scopes those, perfect for deep sky observing.
Guessing that isn't an Sky-Watcher Stargate 450P Truss-Tube Dobsonian?
Pictures look similar.
18" Stargate
Not convinced on these air tube tents, since putting up my pole tent alongside a friend's air one. It looked a lot more hard work, with all the pumping.
I'd been mulling over whether I should have paid the (quite considerable) extra to go for the air version of mine when I got it last year, but am in no doubt now.
Shouldn't there be a mirror or some optics? I can't see any.
Both mirror are protected with covers when building it, in case of little accidents
At the bottom of the scope there's a large black circular cover hiding the mirror, same at the top for the secondary mirror.
May I ask how you go about cleaning the mirrors, given they're totally exposed?
It's a phenomenal-looking thing. Practical sculpture!
what is that telescope and how insanely expensive is it?
The scope has a coat/shroud that protects the mirrors when in use.
You don't clean them, saying that, I have cleaned my 22" mirror once, by using distilled water in a small paddling pool. The 22" mirror weights over 25 kilos so not an easy job, just ran the water back and forth over it gently. In a few months I'm getting the 22" mirror recoated by Orion Optics as its been 10 years.
The 18" mirror on that scope is ribbed and attached to the base so not an easy task to remove.
Another telescope, a little brother to my other scope.
That makes my 250px goto look like a toy
Do you post on SGL?
