Taking performance inspiration from the venerable Nagler series, then combining the optical design properties of both an eyepiece and Barlow, the Tele Vue 41mm Panoptic Eyepiece 2" Wide Anglehas a 6-element/4-group lens configuration that produces a generous 68° field of view and improved edge-of-field performance, while minimizing size and weight.

This eyepiece has the longest focal length in the series, and one of the longest that Tele Vue offers, to produce a low magnification on most optical tube assemblies (OTAs) — making it ideal for wide-field observations of the night sky and most lunar, planetary, and deep-space needs. It is outfitted with fully multi-coated optics to maximize light transmission, color rendition, and contrast, with blackened lens elements that limit internal light loss and diffraction. It also has a fold-down rubber eyecup that helps to block stray peripheral light, avoiding interference with the views and further enhancing contrast. Its exceptional 27mm eye relief provides ample room between the lens and eye to prevent accidental contact that can interfere with views. This model has a large 2" barrel diameter to make it even more comfortable to view through, and a textured rubberized grip for sure handling. This eyepiece is parfocal with the 27mm Panoptic eyepiece, requiring little or no refocusing when changing between the two.

Q: 1. are the Delos series eye pieces par-focal?

A: Yes it is. This is parfocal with Tele Vue Group B eyepieces so no refocusing is required when switching between eyepieces within the group.

Q: 2. Is it advisable to use a barlow lense with Televue eyepieces?

A: This is a fairly high powered Eyepiece. I would only go with a Barlow if you had a Scope with a large Objective around 8", and up.

Q: 3. B&H review note says Delos 8mm eyepiece is parfocal with GROUP B, what is that?

A: That is referring to compatible Parfocal Group 'B' Eyepieces. Here is a list of those eyepieces: 8 - 32mm Plossl eyepieces All DeLite eyepieces 19 & 24mm Panoptic eyepieces 3.5 - 12mm Delos eyepieces 16mm Nagler 5 eyepiece All 1.25" Nagler 6 series eyepieces

Q: 4. What's the condition of Ethos EP?

A: The USED Tele Vue Ethos 13mm Ultra Wide-Angle Eyepiece (1.25"/2") Used Cat #2699851 • MFR #ETH-13.0 Condition: 9 Minor surface marks Very good condition; overall looks clean but may have minor signs of use/surface marks. There are no scratches or blemishes to the optics.

Q: 5. How will this lens perform with the Celestron 1100 CPC Goto?

A: @ 2800mm of Focal length on the C11 you would be off the chart at almost 600X magnification. Way too much. Televue recommends not higher than 350X magnification. So the 8mm version would fit the bill better.

Q: 6. Good day,I got a Celestron NexStar Evolution 9.25 last week and from the reading it seems that it would benefit greatly from better eyepieces than the supplied stock ones.The telescope has Focal Length 2350 mm and Focal Ratio 10.I'm reading good things about the TeleVue Ethos.I was thinking about getting the Ethos 21mm. Would that be a good choice for my telescope?Also the Ethos SX 4.7mm, but maybe it would be too much power for my telescope? The supplied stock 13mm seems quite shaky as it is, using it from my apartment balcony.For the Ethos 21mm I would need 2 diagonal. Would TeleVue 2 Everbrite Diagonal - Satin be a good choice? Would it fit my telescope?Or maybe the Meade Series 5000 Dielectric Diagonal (2 ) as it seems to be supplied with Schmidt-Cassegrain to 2 adapter?Would there be a big difference between these two diagonals in the picture quality or not really on my telescope?What is the advantage of getting Ethos 21mm and Ethos 10mm versus Ethos 21mm and a 2x Barlow?Any advise/recommendations would be appreciated.Thanks.Regards,Andrej

A: I would personally go with the 21mm Ethos model. The 4.7mm will be overkill I think. You could still use it, but you would notice some shake for sure. I would go with the Meade 5000 Series for the Diagonal that would be a better choice.

Q: 7. what is the percentage of distortion.....?

A: It would really all depend on the Telescope you have. Unfortunately I do not have that type of information, my apologies.

Q: 8. How will this TV 32 mm plossl work in a Celestron C5 spotting scope?

A: The Celestron C5 127mm f/10 50x Spotting Scope (OTA Only) BH #CEC5SB • MFR #52291 came with a 25mm eyepiece The Tele Vue Plossl 32mm Eyepiece (1.25") BH #TEEPL32P • MFR #EPL-32.0 is a upgrade eyepiece becaus og better glass and coatings on the elements

Q: 9. Is this a good eyepiece and is it compatible with the Celestron Nexstar 105 GT telescope?

A: Televue Panoptics are excellent eyepieces. Very sharp, clear images. To determine if an eyepiece is compatible with your telescope you first need to calculate your telescope's Maximum True Field of View, then calculate the eyepiece's True field of View. Eyepieces that have a True Field of View greater than your telescope's Maximum True Field of View will cutoff the image and have chromatic aberrations around the edges. Generally speaking, it does not hurt to go a little over tFOV with quality eyepieces, but the more the eyepiece's tFOV is over the telescopes's max tFOV more of the image is cutoff and the worse the chromatic aberrations get around the edges.There are several very good free eyepiece calculators available on the web to calculate Max tFOV, and help determine eyepiece compatibility.

Q: 10. Could I use this with my Meade 125 etc?

A: If your telescope has a 1.25 eyepiece opening then this eyepiece will work. To determine if your scope does I will need to know the exact Meade Model that you have.
