Let's talk about the Hubble Optics UL16
      #4887955 - 10/30/11 12:47 AM

The UL16, an ultralight 16" f4.5 compact Dob with an introductory price of $1995!? Heaviest component, the mirror box with mirror, weighs just 25 lbs. What's not to like? Or is this too good to be true? Found out about this scope in the vendors forum on Cloudy Nights.

I know I am extremely tempted... But I don't have the money!

The only issue I can see with it straight away is the lack of baffling opposite the focuser. Otherwise, a great amount of thought and consideration seem to have gone into its construction. I guess it won't be long before someone jumps at it, given the low, low price.


Clear skies!

Looks fine and the price is great. I don't see any dsc's?

I'm on the fence. Mostly a financial consideration. I just bought a moby expensive 5" APO refractor. Now this!

I saw that just the structure of a 14 inch is just 1.1K!
How do they do that?

Like all these scopes, it simply needs a light shield and/or a shroud.

So, that's why I'm wondering if the whole thing is too good to be true? Or maybe someone has finally figured out how to bring hi-tec mass produced engineering and manufacturing to the Dob world. After all, why should a little metal and glass cost an arm and a leg these days?

You can buy a shroud for $85, but it does not extend up to the eyepiece holder, which sits in front of the top connector ring

It does seem interesting.

Here is a link to a previous thread talking a little bit about this structure (not necessarily the 16" structure).

regards,
Kevin

Ok, but how good are the optics? Despite the unconventional hole in the mirror, aren't these still machine-ground mass produced mirrors? A 16" Lightbridge may have just as good of optics for slightly less dough. Of course it may be well worth the small price difference during this promotion to get the lighter weight UL16. It does seem like a great value at the introductory price, but a lot of people in the 16" Dob market are looking for a premium mirror. Once the introductory pricing ends and it goes up to $3k, will Hubble be competing against Meade or against Obsession?

I agree with you regarding the optics. There seem to be diverging reports. Although, lately reports have been rather positive.

I just find the structure itself interesting. Someone who already has a classic dobsonian, and wishes to go towards an UL, might be interested in buying just the structure and then use his or her mirror, secondary etc...

If anything the price will go down, not up. HO's mirrors for instance are 3x as expensive on their website, compared to what HO sells them for through their eBay store. I can't imagine as a discount vendor they would ever price thier products to compete with a premium vendor like Obsession. As for the optics, I have a 14" and have been very happy with the mirror.

Those scopes have been offered for a year and not one CN member has had the guts to order one yet?

Holy collimation, Batman, how would line up the mirrors if there's no center spot?

I don't know about this scope but their other ultra lights, the ones with the ugly square frame before the mirror cell, I played with at NEAF 10 [they made them for Orion] and thought it wasn't stiff enough. It definitely wasn't buttery smooth. Very disappointed.

It doesn't appear the mirrors for sale on their Ebay store have holes in the middle. I am thinking their Newtonian mirrors don't have holes in the middle, maybe some of the other types do?

No idea where the hole thing is coming from...
