Engineered to Al Nagler's uncompromising standards but at an entry-level price, the long-focal length Tele Vue Plossl 25mm Eyepiece produces a low magnification on most OTAs for both near and deep-sky observations.

It is made using diffraction-limiting high-index glass lenses in a 4-element/2-group configuration to keep light on-axis and reduce astigmatism and edge-aberrations across its generous 50° apparent field of view. Fully multi-coated optics, blackened lens elements, and anti-reflection threads complement the optical components to improve contrast and light transmission, while limiting its loss. Its long 17mm eye relief allows users the room to back off from the eyecup for a more comfortable viewing experience with a reduced risk of accidental contact with the eyepiece lens which can cause vibrations and interfere with views. Ideal for fast-focal ratio OTAs, the eyepiece features a standard 1.25" barrel to be compatible with the most popular size of focuser and accessories, with a convenient fold-down rubber eyecup. This model of the Plossl series is parfocal with all Tele Vue Group 'B' eyepieces, allowing you to change compatible eyepieces without having to refocus — saving time and limiting vibrations.

Q: 1. Does 4X powermate, 2 , fits in to SCT rear cell adopter(2 ) or directly in to SCT rear cell(I have 8 SCT). In other words how do I hook up this 2 powermate to rear of 8 SCT.Second Question: I have a cannon DSLR with T ring and 2 adopter. Does this works with this?.

A: 1) The bare end of the 4x Powermate barrel does slide into the 2 adapter that screws onto the SCT rear cell.You'll need to make sure the 4x Powermate is firmly secured into the 2 adapter since the 4x Powemate is a bit heavy (especially with the camera attached!).2) No, the camera cannot be attached to the 4x Powermate by simply using a 2 adapter and Canon T-Ring.To place an SLR camera onto the 4x Powermate (unfortunately) another adapter is necessary, which is the TeleVue 4x Powermate T-Ring.The 4x Powermate has to be partially disassembled then the Televue 4x Powermate T-Ring gets screwed onto the 4x Powermate. Then, the Canon T-Ring is screwed onto the 4x Powermate T-Ring. Then the camera can be attached to the Canon T-Ring.

Q: 2. I have a 2x Powermate and mount it directly to the 90 degree Televue Everbrite dielectric on my TV-85 for viewing with both the eyepieces and attaching my DSLR via the Powermate adapter with T-ring. Is this how the 4x mounts as well?

A: If I undestand your question correctly, I say YES. I have used my 4x Powermate on my Meade 7 LX200 Mak-Cass with a 2 Diagonal. I dont really need that much magnification on my scope when viewing VISUALLY, why I bought it was for shooting Prime Focus using my Canon T3i DSLR. For this it performed flawlessly. Im pretty sure you are aware these Powermates are a step up from the lowly Barlow and its quite noticable once you've used both and compared the differences ! Just be sure you have the 2 adapter if you are using this 2 Powermate. Aside from that, keep looking up ! :-)
