Congrats! That's a great looking combo. Hopefully you can get it out soon. 

Looking forward to doing just that in the next week or so clouds willing.

Congratulations on the new scope. Its a new moon weekend so there will be lots of new 6" refractors set  up in dark open skies this weekend. Mine will definitely be!

 

I've rounded up my astronomy friends and we are going to make a weekend of it while the weather is still cooperating here in California!

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”.

What happened to these FPL53 150mm F/7 Triplets? Are there any more of them hanging around? I suspect that tomorrow night when I first light the AT 152 with the  FK61 and Lanthanum the scope is going to blow me away after having an AT 130.......

Last night saw the first light on my AT 152EDT Phil is 100% right on with this scope and the 152 really impressed me so I started a thread on my first light. The scope really is a treat.

 

Thank you Phil smile.gif

I think it is time we see someone do a cheaper 7" ED at F/9.  Meade sure failed but that was 20 years ago and things have changed. Say a price of around $4.5k to 5.5K.

Never gonna happen IMO as there's not enough of a market and  the small percentage of people who do want one, end up fixing the older Meade 178ED.

I would never touch one unless i could test it first and it had the cell fix.

I fully agree with you. would be foolish to think otherwise.

My 178ED came with the cell fix and gave awesome views right out of the box.   Cannot ask for more.

Does anyone know if you can put a Starlight motorized focus system on this focuser? Will an HSM 3 fit on?

It would be great to see some 180ED f/9 scopes for $8,999. Visual only. If ca was difficult to find and the quality was like the 152 they would get some notice. Or they could lose some money.

God bless @AstroTech for making beautiful scopes for a minuscule community who seems to have forgotten we do this for fun.  Thank you for taking a financial risk by bringing new equipment to market. Sure a TEC 140 would be swell, but I can get the AT152EDT and a AT92 and a WO Star71mkII for the same price.

Any know what the image circle is with the dedicated 0.72 flattener/reducer?  It is missing from the AT webpage.

Sorry, I use the Riccardi FR/FF. At .75x for the 63mm version the IC is 40mm and for the large 82mm version it is 50mm.

I called AT today.  An engineer "thinks" it is 42mm, but was not 100% sure.

To the best of our knowledge the image circle sits at 45mm.  I can only assume Ken was referring to it covering a 42mm industry standard image circle.

Thank you for the clarification.  Are you planning on putting this in the specification part of your website?  You guys are doing a great job.  Thank you for investing your research dollars into this scope specific reducer.  I hope you sell a lot of them.

My problem with their flattener is the camera side is at M48, no option to stay at M54, M63, M68, all available on the focuser, but once you put the FF on it you're forced to M48. Rather than $60 or more on adapters that wont regain my FF wide opening???

Doesn't M48 cover a full frame sensor?

It may correct a full frame, but light fall off is better the wider you can get. My Nikon Z6 has a 52mm opening, much larger than standard Nikon F Mount. I have the extensions and connections to the scope all at M68 to keep a wide open throat. If I add in their flattener after the focuser I am constricting the opening from M63 to M48, then back up to M68 to attach my camera.
The small Riccardi is M63 thread, and the large is M82.

Hi Carl,

 

Please forgive a noob's questions:

 

I too have a Z6, which I intend to use as my first astro-camera before digging into fancier OSCs or Mono gear. I also have on order an AT152EDT due in Sept-Oct I've last heard. (And an AT80EDT. Yeah, I couldn't decide between wide or deep field, so...).  What do you screw onto the Riccardi's M63 threads that then clicks into your Z mount? If you can tell me soon enough I'll have time to cancel the flattener I've ordered with the scope and use your solution.

 

Bob
