WOW astronomics that AT 152 EDT really looks sweet and at 25 pounds with a handle to help move it around that is most excellent.  The review on the prototype posted here are very encouraging too.

FK61 glass made by CDGM in China usually has an Abbe Number of 81.6 − very similar to FPL-51. It is not the equivalent to FPL-53, which has an Abbe number of at least 94.94.  

 

There are 150mm FPL-53 Triplets available today, like the Esprit and the TS Photoline, but they may not be price competitive with the AT152EDT (at this time).  The TS150 has a Starlight 3.5" focuser, so that explains some of the differential in price. I would be willing to bet that there will be a FPL-53 150mm Triplet at a similiar price point by the time ths AT152EDT is ready for market. Competition is good.

There is also a Lanthanum element in there too. The combination works really well. I doubt you'll see anything at the same price point with the same correction.

The focuser is very good. I normally change out focusers for FT's but this one doesn't need it. It's 3.5" and very well made. Its all about the prescription the glass is only one factor.

Have you ever tried an AT111EDT? That's FPL-51 and a design by Thomas Back and shows how a well designed implementation can work.

Take a look on Astrobin for AT111EDT images.

Ok , while I am interested, I will wait for more details on the objective performance. The price point i attractive. I have a TS FPL-53 APO and it is wonderful, I want to see the Abbe numbers on the objective.

We had an FPL53 150mm f/7 triplet. Absolutely zero people cared.

I think a 152 triplet at $4k with a Lanthanum and Fk61 would be a pretty big deal. I know a few companies that advertise 5” with a low dispersion ED Element and Lanthanum for a few hundred less than our 6”.

The design is more important to me then the glass types. The proof will be in the pudding when these are released in the next few months.

I truly wonder if anyone has ever based a vacation on the premise of visiting a "Telescope Dealership". To be honest I would seriously consider it.waytogo.gif

The TEC 160ED is also a FPL51 F8 triplet and is awesome for visual use at least.

 

Of course TEC spend a lot of manufacturing time on these big refractors. But at the end it works very well.

 

A shorter than F8 6" refractor would require FPL53 / FCD100 or even fluorite glass

Michael, any word on the expected optical specifications? Strehl, wave front etc?

Also will it be black and white like the prototype, or the Aston Martin grey like the other AT scopes?

My current production AT130EDT is white, not gray. I think most of the current AT Refractors are white as well. Perhaps some of the older AT's were gray but not the current line.

It would be so nice to see the Aston Martin grey trim come back.  It is such a distinctive and classy look.  I seem to remember Mike saying that the manufacturer couldn't do it for the current scopes...80, 115 and 130 triplets.   My original AT111 and the little AT72 are both Aston Martin grey trim.   Beautiful.  smile.png

I can't help Phil with "work" (whatever that is..... retired guy alert)..... but Clear Sky Chart for NY's Southern Tier is predicting clear for tonight, and a rare "excellent seeing" for a few hours..... with a nice moon..... after that, the forecast is snow showers.....
