Product Description

This short focal length Takahashi eyepiece uses a proprietary five-lens optical design to provide a high magnification capability with exceptional sharpness and contrast. The eyepiece uses an ED (Extra-low Dispersion) glass element for outstanding color correction.

This five-element Takahashi is similar in its optical performance to a classical four-element Abbe-type orthoscopic. It has the high contrast, low ghosting, flat field, and excellent edge to edge image sharpness for which orthos are famous - but has a 52° apparent field of view that far outstrips the 40-42° field more typical of a conventional ortho.

The 7.5mm Takahashi makes an excellent lunar and planetary eyepiece with scopes of all optical types - refractors, Schmidt-Newtonian and Dobsonian reflectors, catadioptrics, and more. Its high contrast and low ghosting also excel at splitting close binary star pairs, resolving globular clusters, picking out small planetary nebulas against a stellar background, etc. It typically provides the maximum useful power with an f/15 Maksutov-Cassegrain.

A great lower power companion to the 5mm Tak LE. I use it mostly for viewing the moon, star clusters and nebulae, and find that it gives a good dark background to dim fuzzies. Good sharp focus across the entire field of view, and not even a whiff of chromatic aberration. (Posted on 1/9/2019)

I was surprised by how well this eyepiece (7.5mm LE ED) performed in two of my refractors (80mm f/7 apo triplet and 102mm f/9.8 achro). I purchased it to max out the useful magnification on my 180mm mak-cass, but haven't had a chance to use it in that scope yet. I mainly use wide-FOV eyepieces (82-deg to 1000deg), but the 52-deg FOV was not as limiting as I anticipated. My observations are mainly from a light polluted suburb 35 miles east of Los Angeles, but the views of Andromeda, stars in the Pleiades, Sirius, Rigel, Betelgeuse, Uranus, and even Neptune and Mars were very good compared to my other short focal length eyepieces. Compared to my 7.5mm Plossl, the Takahashi 7.5mm LE ED showed a clear view with no glare or light scatter. Again, I was very surprised at how well this little eyepiece performs.

Since purchasing it, the Takahashi 7.5mm LE has become one of my favorite eyepieces for planets. It yields 190X in my 8" scope with a nice amout of eye-relief. The 52° field of view allows you to keep targets in view easier, even at high power. I find the view to be sharp to the edge and free from any distracting glare, scatter or qhosting, evidence of some excellent coatings. With a build that oozes quality, it also looks nice in my eyepiece case. (Posted on 8/4/2017)
