Hello All!

 

Last November I ordered a 10” f6.3 Ultra Newtonian for a shop in the UK. It was supposed to ship six weeks ago. My most recent inquiry (a few weeks ago) they told me they had no idea when it would ship that it was in line for assemble and testing. But there where many, scopes ahead of me.

So, I am about to start thinking about canceling the order and try to go with a US shop.

 

A general outline of the scope:
Visual use only
Price range $2,500- 3,000
Again, I would be looking at a 10” Newtonian in the f6 -f7 range.
#1 priority is it MUST have superior optics!
Maybe a truss design might consider a full tube design
Light weight/ portable
Durable
Maybe DSC
Maybe a Wedge (I know more $)
High end focuser.
A tried-and-true design (OTA and mount)
Please feel free to ask questions if I have missed something.
Effective mirror cooling system

 

Any thought would be appreciated.

 

Many, Many Thanks in advance!

There are definitely options to investigate but when you take into consideration that you are looking at > $1500-2000 just for the primary mirror I don't think this happening for anywhere near your budget especially considering freight charges. (Most custom structures start at $3k without optics...

DBullard,

Thanks for that input. The budget can be increased if need be. I appears that a lot these folks Have offerings that start larger than 10" 12 1/2" I wonder if there is any economy in going larger. 

 

If you have custom folks in mind I love to hear about them. Also taking your point if you have anyone that make premium (vs a custom) scopes I would be interested in that as well.

 

 

Many Thanks

What if you found a nice Parallax 10” newt in the classifieds? You never know what a “wanted” ad will bring.

I always read excellent reports on this forum about "Teeter's Telescopes LLC" The scopes are absolutely gorgeous! However, you will need to have a serious discussion with your CFO as prices with premium optics start at double what you're thinking. Their website is impressive...Good luck, I hope it works out for you! waytogo.gif

Are you certain you can recover any deposit you made on your current scope, especially if they ordered the optics? 

 

Assuming you can, like Ray indicated, you could put a WTB ad in the classifieds, or reach out to your local club members to see if they have something that fits your needs. .

 

It would be more likely to see used premium dobs (obviously not on a wedge) from New Moon or Teeter that would be in the f/5 range, although someone may have a f/6 from either manufacturer. Many of those scopes were sold with premium optics. You can always upgrade those too, if you don't like the optics that come with that used scope.

 

For Zambuto optics  you would be waiting a year or so per his website. Swayze actually has a couple of 10 inch mirror options available now. I am sure that other good opticians could give you some estimates on completion. 

 

My 10 inch f/5 Teeter STS model has an OTA/cradle assembly that weighs 41 pounds, for example. I don't know if that is light enough for you.  My solid tube would be heavier than a similar truss design. Some of the New Moon hybrids look quite light and could be outfitted with DSCs. I highly recommend the Nexus DSC that Teeter installed on my scope. 

 

Dennis at dobstuff also indicated he has some "premium": 10 inch f/6 optics available per a post on his Facebook page. You could contact him regarding his options. 

 

Good luck.

if it helps, I summarized my 10 inch Teeter last year when I picked it up at this post:

The wait time on a newly placed order is not going to be short, so keep that in mind too.  

 

Check out astrosystems as well.  I don't know if they go down to 10", but they are great, and come in kit form.  If you are able to assemble the pieces yourself it is a good way to learn about telescope making and save some money.

Order a 'commercial grade' Dob -- Who knows - you might actually like it! --- or at least it could well come with good optics. I've heard from a lot of happy GSO Newt optics owners lately.

 

You can always 'do the kit thing' - taking the optics out of a 'commercial grade' Dob and putting them in a completed kit.

 

Even if you buy a 'commecial grade' and get it now - to use while a 'premium' is being built - you can sell it later - with the price difference being 'the price' of observing and learning with it over a year or so while the 'premium' is being made.
