18mm Tak Or with glasses?

[Harmony Smurf]

Curious if anyone has had the opportunity to test the 18mm Tak abbe ortho with glasses on.  The eyepiece isn't common where I live so I can't test before purchasing it.  I wear glasses for astigmatism and also generally observe with a binoviewer. 

 

thanks in advance

BTW, I am also considering the HD ortho 18mm as it appears to not have much of a recess of the lens. 

 

Another thing to consider is that the eyepiece that had the shortest eye relief with my glasses on was the 12mm Dual ED which has a stated 13mm eye relief.

You may be better off considering the 18mm Tak LE if you wear glasses. However, if you're using a binoviewer with gpc or barlow, i wouldn't buy Tak eyepieces at all. With a binoviewer with a barlow attached, even a cheap pair of 16.8mm Super Abbe Orthoscopic eyepieces will perform every bit as well as the finest planetary eyepieces available. And they are fine for spectacle wearers too!

Another alternative to Takahashi are pseudo masuyama's such as the Japanese made Celestron ultima's, Parks Gold and Orion Ultrascopic's, Baader Eudiascopics and Meade 4000 series among others. These often have better eye relief than some of the Tak eyepieces which can have their eye lenses set deep inside the eyepiece body. They are nolonger in production but do come up second hand quite regularly.

The 18mm orthos have about 14mm of eyerelief. I have 2 Tak 18mm orthos that I use with the Denk Binotrons- they are very good. However I find myself reaching for the 25mm and 32mm TV plossls more often than not for the binos/powerswitch. The 32 TV plossl needs the eyeguards IMO.
