APM/Riccardi 0.75 x Apo Reducer/Flattener
Posted 10 May 2012 - 02:55 PM
The Riccardi Reducer was now also tested with success on the TEC 140 Apo and TEC 180 Fluorite and the chinese triplet FPL 53 Apos from german based Telescope-Express company.
Massimo Riccardi, famous optical Designer from Italy, designed for APM-Telescopes a new 3 element ( with ED Glas) 0.75 x Apo-Reducer/Flattener Corrector for all TMB-APM-LZOS Apochromatic Telescopes. Tests show that it also works on Apos from other manufacturers very well
The corrector was designed to work with most diffrent telescopes, by changing little the backfocuse only.
The Coating of the corrector is optimized for modern CCD Camera spectral range.
The correctors performance was designed to have very zero to very low edge vigneting, tight spots nd a large corrected image circle
We choosed in the design 2 diffrent size of reducers
Model 1, small version has at both ends standart Metric M63 x 1 thread for which many adapters available off the shelf. It screws straight into the 2.5" Starlight Instruments Feather Touch focuser and new APM 2.5" Focuser
This small version has a corrected image circle up to 22 mm for the APM Triplets 80/500 and 80/480 and corrected image circle of 42 mm for all APM/LZOS Apos 100 mm up to 152 mm and a backfocuse from corrector mechanics to CCD chip, little above 70 mm
This smaller version works perfect with our Apo Telescopes from 80 mm up to 152 mm diameter with 2.5" and even better with 3" focusers
Model 2,big version has a corrected image circle up to 52 mm and a backfocuse from corrector mechanics to CCD chips, little above 75 mm. The big version has at both ends a metric M82 x1 thread and works perfect with 3", 3.5" and 4" focusers. Here also many adapters available off the shelf.
our own Maschine shop can and will make you any necassary adapter for perfect spacing and your focuser.
The big corrector is optimized for all TMB-APM-LZOS Apos 100 mm up to 254 mm diameter , plus APM Apo 107/700 and works also well on some chinese Apos with similar sizes and f-ratios

thanks to a customer request Massimo Riccardi checked how this Reducer works on a Ritchey Chretien and to our surprise he found it works perfect on Ritchey Chretien Telescope

I also have the Meade 6000 80mm APO, will it work?
Can you provide benefits that I would enjoy on my scopes with this product?
Posted 27 February 2013 - 11:13 AM
Posted 27 February 2013 - 03:29 PM
it will work perfect on your 14" ACF yes
it will NOT work on your 80 mm apo, because you need minimum a 2.5" focuser and minimum 7.1" backfocuse
the benefit you will have on the meade is a apochromatic corrected 0.75 x FOV for imaging for full format CCD chip
Posted 27 February 2013 - 03:30 PM
like any corector, this is also designed for imaging work only.No benefit for visual , sorry

1) Reduce my focal length
2) Further flatten the field
3) Eliminate need for the Meade Reducer/Flattener
I use a Canon 5D Mark II, which is full frame, so this should be awesome. Which unit would I need?
Posted 27 February 2013 - 09:24 PM
Reason I ask is that ES has a hole in their inventory for a FR/FF for the 127ED.
Posted 28 February 2013 - 08:54 AM
excactly , one german used such Meade , my reducer and his full format CCD and thanks to him we know it works :-)very well. Then i asked Riccardi to check how our apo reducer works with RC and he was himself surprised how well it works with RC .
if you want one, drop me a email to firstname.lastname@example.org and we will get you the quote
Posted 28 February 2013 - 08:55 AM
the ES 127 has a 2" focuser only and my reducer requires minimum a 2.5" focuser , so with 2" focuser it will not work, sorry

Posted 28 February 2013 - 04:47 PM
What I meant to ask is: "has this FR/FF been tried on a 127ED"?
I tried TV RFL-4087 with 2.5" custom adaptors and it didn't flatten the field so I am looking for a good FR/FF that is known to work with 127ED.

the reducer has a M63 x1 Thread and needs a threadet adapter for the scope
