We starting a new Deep Sky Refractor telescope project . Our 180 mm f/6 achromats reached slowy success, but finaly they found owners who love here performance. We have 1 last piece left in stock for sale. Quite a few of the optics has been send back to our manufactor due non acceptable optical problems, so we have plenty tubes left and thought about what to do with the stocking tubes without Optics.
So we discussed the new project , a douplet refractor also usefull for planetary observing with medium power . To make it not to expensive we checked the cost for a FPL 51 version and our design comes out not to bad , on the free market such optics would be called ED Apo , but I am realistic and this optics have nothing to do with an apo , but they are between achro and apo, so we give them the right name and call it APM Deluxe Semi Apo.
We made tight specs and a good contract with the lens maker , so we have not to worry about quality issue, he pays all returns for bad samples.
To stop upfront any speculations, we make this lenses in China and nowhere else. Only there we can get such good price to give you a good product by hand.
The mechanics from China would be a idea, but the cost with shipping and duti to us, comes out at a similar level as if we make them here in germany where we have full production controle, so we will do the mechanics here in germany. Only the focuser will be purchased from our great supplier Starlight Instruments in USA.
We want for each country the very best possible service before and after the sales, therefore this new Telescope will go to you through your local dealer and so we add local dealer profit.
The estimated retail price for this 180 mm f/6 Semiapo with CNC Tube, CNC Tuberings, 50 mm finder , Starlight focuser, dovetail rail will be about US $ 7,990. In Trade we promisse you top notch non compromissed quality.
The complete optical tube will have a weight of about 12 kg = 26 lbs and it will have a transporting length of about 920 mm = 36.22 inch.
The Synta EQ6 SynScan Goto Mount will handle this scope for visuel purposes very well
The manufacturing time for the first run will be about 4 month , if it pass our test , we start shipping , if not we delay shipping. But since we work with this optical company since some years and teached them to get better and better ,we are very optimistic to have from start on good results.
To see what you can expect , see here our spotdiagram of our 180 mm f/6 achromat and compare it against the spotdiagram of the 180 mm F/6 S FPL 51 Semi-Apo which you see attached. You read there 178/6, that was the first idea, but now we increased to 180/6
thanks for your interested in our new Deluxe Semi Apo Project
For now you can go on our waiting list with no deposit, or if you serious trust us as we do in that project, fix your order with a deposit and you will be by the first who get them.

apm的fpl51的smeiapo 180的口徑，色差貌似控制的還行，目視觀測應該很爽。雖然效果不及fpl53的apo，但性价比很好，口徑也打，適合要求不是非常苛刻的目視觀測，估計這個口徑看行星應該很震撼了。 |
