i remember seeing the sky and telescope video about
it on youtube and saying whoo at the right price that
will be a real challenge to the big apo makers.

in europe their is the TS 150 Apo thats looks a
great scope too but not many have bought it their
just one guy with nice pics its around 5800 dollers
but when you have that money are you going to buy
that scope.

one use FPL-53 the other hoya FCD1 which is just
like FPL-51 it seems many americans tend to buy
brand names even if it means getting a smaller
apo and europeans go for best glass type then brand.

The ED152CF is alive and well and just beginning to show up in stores. I know that Woodland Hills Camera has them in stock and I've heard it said that Astronomics has them in stock as well. I have one that I haven't been able to really work with a whole lot due to time and weather.

It's a very nice telescope. I hope to post first light images soon.

Here's another standing away from the scope......with 4.5 pounds of camera gear attached on my AP900. Note that there's only a single 18 pound counterweight. While the scope is physically really large...it's lighter than it looks. I weighed it as shown here and it tipped the scales at 29.2 pounds. So with a diagonal and finderscope as it's shipped - the published 27 pound weight is accurate.

hm. this means a Mach1 can carry it for imaging?

Technically, it probably can. The telescope is physically quite large, something the Mach 1 might find difficult if a breeze is stirring.

I believe that one of the ES 152mm telescopes was a door prize at Astronomics grand opening last fall. I sure would like to have scored that puppy! :(

There was one in their showroom mid December. It seemed to be slightly different than the prototype I looked through at Okie-tex 2011

But how durable is the carbon fiber? How will it look in ten years? Numerous scratches, maybe? Personally, I'll stick with powder-coated aluminum, which has a good track record for durability.

What is the height of the pier...or, more to the point, is it mounted in the shallow or deep end of the pool :lol:

Nice looking scope Mike!

The pier is 48".....but I'd probably find it easier to use if I mounted it in the shallow end of the pool. Just like with people....it looks taller when I'm standing next to it.

Amazing scope! I'm looking forward with great anticipation to read about its performance.

I'd be more concerned about cooling and expansion coefficient rates for accuracy of focus during long exposures. Not to mention lens cell design as well as accuracy and figure of the lens.

AP ain't AP because they have a durable OTA.

I was writing only about the tube, not the optics, and I do not image, so I do not care about accuracy of focus during long exposures, etc., but certainly there are those that do. Because TEC, Astro-Physics, and Takahashi do not use carbon fiber, I tend to think it must not be a good idea.

Some may not care about durability in your $6K telescope, but I certainly do. TEC and Tele Vue, for two, have very durable optical tubes, along with their excellent optics and high price tags.

Beautiful Mike! I can't wait to get mine. But every time I plan to pick it up, we have a snow or ice storm! Talk about new telescope bad luck. Luck's so bad, the skies won't even let me pick it up. :bawling: Perhaps this Thursday! :jump:
