This finely crafted 2" dielectric 1/10 wave diagonal from Baader Planetarium features their patented ClickLock system for fast and secure clamping of 2" eyepieces and accessories.
The durable scratch resistant dielectric mirror maximises light transmission and is figured to 1/10th wave surface accuracy to minimize aberrations. It also also rejects deep UV and IR radiation, making it suitable for solar viewing with all White-Light and H-alpha Solar Filters.
A fine diagonal that will upgrade the optical train on any telescope equipped with a focuser that accepts 2" eyepieces.
Note: A 2"-1.25" adapter is required when using smaller 1.25" fitting eyepieces.

A solid and well made piece of astro equipment. The oversized mirror which is finished to 1/10th wave accuracy provides a crystal clear image. The diagonal has tons of clear aperture and the dielectric mirror also screens out UV/IR making it ideal for solar as well as night time observing. The clicklock operates with the smallest of movements. This diagonal is for life. Great service from FLO again.
Baader Dielectric 2" Clicklock

Very high quality and very solid. Compared to plastic 1.25" diagonal the image seems cleaner and better to my first time impression. The super hard dielectric coating makes for peace of mind when cleaning which will last a lifetime or generations.
The click lock is superb and very sturdy. I also bought the 2" to 1.25" eyepiece click lock adapter which is also superb like this one. Dont make the mistake of thinking you need to clamp it super tight. I did read the instructions too late where it says you dont need to tighten the click lock very hard. I tightened it pretty hard to the 1.25" adapter and it was hard to open. To open it again I unscrewed the click lock from the housing and got it off by using two hands. This is not a fault of the design but just as the manual states, you dont need to pull the lever super tight. A little twist and it holds very good. The mirror and clear light cone path is huge. This thing is built like a tank. I have wiped the mirror with a fiber cloth and using Baader Wonderfluid cleaning solution and I think there came off a fine micro layer of dust, perhaps from the manufacturing process and now the mirror is very clean. I would buy this again if I needed to. I have confidence this diagonal can hold any kind of 2" eyepiece in existence without breaking a sweat and without worry of mind.
-Impressive first time impression of improved image quality compared to plastic scope diagonal
-Zero worrying of cleaning or degradation of mirror over time
-Oversized mirror with maximum 2" light cone path possible
-Very high build quality
-Large available compatible adapter accessories
-Holds eyepieces very good without scratching them and with very convenient click lock twist to secure and open
-Peace of mind that the dielectric mirror rejects invisible UV and invisible IR light. Perhaps more comfortable to use in certain situations, like having UV/IR sun glass protection

Someone said to me that once tried you can't do without it and it's right! Very secure fit and easy to clamp. Very well made and I am confident clamping my Ep's. A very nice item now I just need the 1 1/4 adaptor!
Must be the best diagonal on the market

I have owned many diagonals over the years and this is my favourite and the only one that I still own! If you have never enjoyed a "Baader Clicklock" then you are missing out on the ease that you can change your eyepieces at night in the dark and in winter with your gloves on! The construction is rock solid too.
Very well constructed diagonal

This is a very well-constructed diagonal, and yes the mirror is significantly larger than in some other 2 in star diagonals, and will not restrict the field of view of any 2in eyepiece. The stated light path of 112mm is also quite accurate, this can be quite important with refractors where there is a limited amount of travel on the focusing mount, and some manufacturers quote an inaccurate figure or no figure at all.
