This is a very good low power/wide field eyepiece for capturing galaxy pairs and galaxy clusters, viewing emission and reflection nebulas in their entirety, etc. You can use the calculator below to see how wide a field it will give you with your particular scope. It has a rubber grip ring for comfortable use in cold weather.

It provides a big 7.1mm exit pupil with an f/4.5 Dobsonian reflector for rich field scanning of the Milky Way star clouds in Sagittarius from a dark sky site. As the eyes of some observers may no longer be able to dilate to a full 7mm, however, this eyepiece could potentially waste some of the light-gathering capability of a fast focal ratio scope. Thought should be given to matching its exit pupil size to your eyesight before purchasing if you have a fast focal ratio scope, unless you are content to give up some light gathering in exchange for a wider view of the universe.

This is an excellent choice to replace the so-so 26mm eyepiece that comes with many moderately-priced scopes, not only to improve the edge-to-edge sharpness, but to give a wider and brighter field of view, as well. Excellent eye relief for unvignetted viewing for eyeglass wearers.

Field of view:
The field of view (FOV) is the amount of observable world one can see at any given moment.
50°
Eye Relief:
Eye relief is the distance from the last surface of the eye lens of an eyepiece to the plane behind the eyepiece where all the light rays of the exit pupil come to a focus and the circular image is formed, sometimes called the “Ramsden Disk.” This is where your eye should be positioned to see the full field of view of the eyepiece. If you must wear glasses because of astigmatism, you’ll usually need at least 15mm of eye relief or longer if you want to see the full field of view with your glasses on.

A note on our eye relief figures: Quite often, our eye relief figures will differ from those of the manufacturer. This is because we measure the “usable” eye relief, while the manufacturers specify their usually-longer (but technically correct) “designed” eye relief.

The eye lens of the eyepiece is normally recessed below the rubber eyeguard or rubber rim of the eyepiece to keep the lens from being scratched during use. An eyepiece might have a “designed” eye relief of 15mm (and the eye relief will truly measure 15mm from the eye lens to where the image forms). However, if the eye lens is recessed 3mm below the eye guard, the Ramsden Disk forms only 12mm above the eyepiece body (the 15mm “designed” eye relief, less the 3mm of eye relief made unusable by having the eye lens recessed into the body of the eyepiece). This “usable” eye relief of 12mm (measured from the rolled-down eyeguard – the closest point you can get your eye to the eye lens – to where the image forms) is the eye relief figure we would measure and list in this website.

Why is it important to list the “usable” eye relief? For those people who don’t wear eyeglasses while observing, a few mm difference between the eye relief they expect from the manufacturer’s literature and the shorter eye relief they actually get in real life doesn’t mean a lot. They can simply move a little closer to the eyepiece to see the full field, and never realize that the eye relief is a little shorter than they expected. However, some people must wear eyeglasses while observing, because of severe astigmatism. These observers can’t move closer to the eyepiece if the eye relief is shorter than expected because their glasses get in the way. For these people, the real life “usable” eye relief is more important than the technically correct but sometimes not fully usable “designed” eye relief. We measure and list the actual usable eye relief so that people in the real world can pick the eyepieces that will work best for them.

18mm
Focal Length:
This is the length of the effective optical path of a telescopeor eyepiece (the distance from the main mirror or lens where the lightis gathered to the point where the prime focus image is formed). Focallength is typically expressed in millimeters.

The longer the focallength, the higher the magnification and the narrower the field of viewwith any given eyepiece. The shorter the focal length, the lower themagnification and the wider the field of view with the same eyepiece.

I have an SCT with a 1500mm focal length and needed a lower power eyepiece than the 25mm that came with the scope. On its website, Televue provides excellent guidance on selecting eyepieces. When I checked I found out that what prevents using longer focal lengths is the field stop. With a 1.25" diagonal, I was limited to a 27mm field stop, corresponding to TV's 32mm Plossl. No point in getting a much more expensive 40mm, so I got the 32mm.

What I like: very good value and performance for the price. Clear images.

What I don't like: Nothing. A larger field of view would be nice, but it's a Plossl, after all.

Summary: As with all TV products, there are cheaper alternatives, but the 32mm TV Plossl is competitively priced and produces excellent images.
