Observatory gets completed in Spring. The 16" looks like its going to have a home in it.

I would say the cooling will be much better then somewhat. The open tube should allow a much more efficient cooling time when combined with the Quartz optics.

I have a Paramount ME and a STL-11000M if you need any of them tested or demo'd at the 2014 WSP

Hi Mike,
You have any details, cost availability. Def interested in a 20" for home.

Around $12K, hopefully lower. I would say in the next 6 months. The polishing machines are ready, but they may not start the project until they move into their new $6,000,000 facility.

We will also have the 10" in a truss shortly and I asked about making an 8" truss.

I can put you on the list for the first one if you wish. No commitment needed.

Will this model have the same (I'm sorry, but) inexplicably silly design of having the focuser attached to the mirror cell? Based on what some (now previous) owners have told me that would not support the imaging train I use, no matter how appealing it is otherwise. Has anything thought been given to NOT doing it this way? I know 3 folks that sold their AT RC's because of this shortcoming.

Along those lines, what about the capacity of the focuser itself? I'm really not trying to be harsh here, but the crayford-style focuser in the photo doesn't inspire a lot of confidence.

I earlier tried to ask same thing as gr0uch0. Can we have an answer for is there this same design flaw in these new scopes?

I know we have sold thousands of the scopes and people are using them just fine with various imaging trains. The ones we have out for research purposes have never reported a problem over a 4 year period. I don't have an answer for what seems to be an extremely small sample size. If they all came back defective then I would say the design is quite flawed, however that has not been the case.

The focuser ends up being a stop gap for most folks as they already have a focuser they prefer to use like a Feather Touch, Moonlight, or something super exotic that has remote capabilities.

Fair enough. Seems odd that 3 imagers of the relatively few that I know had issues with sagging with cameras, filter wheels and rotators. Sweet scope otherwise, but this design option still seems like a bit of a head scratcher.

I can only assume the designer believed it was the best way to keep the rear cell and camera aligned. I sounds like the some of the collimation screws weren't tightened down. I mean since the entire system is one piece it would only sag if something wasn't tight. At least that is what my non engineer brain tells me. I might guess they had the 6" scopes and that sounds like a ton of weight on the back of the scope. But like I said in another thread, we have had people with 15 pounds on the back and didn't have an issue. They of course had an insane focuser to support that much weight. And I would assume a heck of an insurance policy. lol

I can only go with what I was told anecdotally, but these were the 10" versions. Not sure what two were replaced with, but the one was replaced with the DSI RC10C where the focuser and mirror cell are decidedly separate.

Are you going to recommend a particular focuser for heavier imaging trains? Do you happen to know what focusers are being used in these 15lb imaging trains?

To that end, what will the backfocus be?

Thanks Michael,
Mark

I suspect that while the ads may be out in China and Europe, it is doubtful that any actual scopes are available there yet since the first production run only started last week, The China ad shows a quantity of zero sold and the European ad says "Ask for delivery time." That doesn't sound like the scope is actually available in either place.

I only posted the European ad link to show that it's not just an isolated dealer who's making promises, it's basically the most important GSO dealers in USA, Europe and China who are gearing up to sell this scope. OF course being in the USA I'd buy from our USA dealer .
The European price is way higher so that's a non starter . The Chinese price is the same as from Astronomics but after adding shipping and duty plus the risk of damage in transit and lack of local support (should someone buy from China instead of Astronomics) it's definitely not an option . These ads are just a good indicator that the scope is real and coming soon. Looks very promising.

These scopes should be an amazing value. However, from my perspective the major problem with these scopes is the lack of a dedicated field flattener. It is well known that RCs suffer from significant field curvature, and this is evident with my Astro-Tech 8” RC even with a medium sized 15.15mm x 15.15mm CCD chip. Are there plans to offer a field flattener for these scopes?
