Hi Fellas....I have commited myself to purchasing a Meade Series 5000 80mm
APO Refractor ( Triplet ). Meade uses the finest Japanese FCD1 ED (Extremely Low Dispersion) glass.....What I want to know is...Is FCD1 ED the same as FLP-53 Glass. There is FLP-51, FLP-52 and FLP-53. I have read that FLP-53 is the best glass......I just don't know what quality or rating the FCD1 ED is. I have " Googled " it but can't seem to find a proper answer to my question. Can anyone shed some light on this...Thanks for anyone who can help.
Best Regards.....Colin...( FlashDrive )
