Triplets are nose heavy, true ? You must have a nice binoviewer for that scope. For balance.

I use a ring with weight on my top heavy scopes and a big finder.

I am sure the view would be insane in my seeing.   I would rather see one at F/9 if i were to buy.  No cheap mount for this scope.

26kg?! Seriously?  A TEC180 weighs 16.5kg.

It does seem a bit much ... My CFF200 has 23 kg bare bones (no camera, FW, corrector etc.)

Is it a doublet or a triplet?

It's a glass with a little less than 200 FCDs in it.  grin.gif

AP1600 should do the trick.

57lbs is a beast.  Would be perfect to mount in an observatory though.  I'm curious about the glass too.  APM has built some great refractors in the past and I have no doubt this one would be too.

... if one could already afford the massive mount needed for this OTA and maybe an obsy, why not going with the top brands, like LZOS, TEC, AP, CFF, TAK or Agema?

Well… Agema has yet to build a 180mm scope and I didn’t realize that 180mm refractors were even available from AP and Takahashi. Stellarvue has thrown its hat in the ring but I don’t think they’ve delivered one, yet. So options are pretty limited. I went with the CFF180. Delivery is expected next spring.

The TEC is oil-spaced and the APM is air-spaced. In order to keep the lens elements aligned, one needs a very robust (heavier) lens cell for a large air-spaced triplet. The lens cell for an oil-spaced triplet is much less complicated. That 180 OTA looks pretty robust as well.

Seems a really nice scope but it has strong competition.

A CFF 185 f6.5 has 17 kg and for non UE countries is 1240 EUR cheaper then the APM 180.

A big plus is that CFF makes a dedicated field corrector for their scopes. TEC I think also makes their own dedicated field corretor.

Both TEC and CFF come with a FT3545, another plus.

Maybe APM will drop the price a little to be competitive with the rest grin.gif .

Well he initially said it was to come in around $10,000. The price quoted now is approximately $15,000, which puts it close to the premium brands. It just seems to me being that close an amount doesn't make it practical to purchase when you can obtain one with a tried and true quality.

Best regards, Richard

I believe the $10k price Marcus announced a few months ago was for an APM 180mm doublet. This is a triplet… a different scope.

Where are the optics made? at LOS or 'somewhere' in the Far East?

China, Markus explicitly said so.
