    Cool First Light Delite



    9/15/18

    I was almost afraid to pull the trigger on this one. I tried a few premium EPs in the past and sent them back, because they did not outperform my mix of Meade 5000 UWA, ES82s and ES68s. However, I wanted to try TeleVue Delites since they were announced. Finally, I caved in and picked Delite 11mm last week.

    This purchase was triggered by somewhat unexpected discovery. While testing Vixen SLVs side-by side with ES82s on planets and faint stuff I noticed that SLVs 50 deg FOV with nice and sharp field stop was not much smaller than ES82s. I observed with glasses and never saw the field stop in any of ES82s due to tight ER. Still I thought I would get at least 60-70 deg out of 82. Wrong! Next time I run comparison between 50 deg SLVs, 60 deg X-Cel LXs and ES82s on daytime targets, and visible FOV of ES82s with glasses on came to ~55 deg at best. Shocking! All this years I thought I was enjoying wide field views, but I was actually using glorified Plossls.

    Dont get me wrong. ES82s are nice EPs, with good sharpness, light-scatter control and high transmission coating. But, they are not designed with eyewear in mind. Same goes for most Naglers, though.

    Therefore, Delites with 20mm ER and 62deg FOV became even more attractive.

    When I pulled Delite 11mm from the box, the first reaction was that they sent me Radian instead.

    Delite11mmB.jpgDelite11mmA.jpg

    But then I noticed some differences. Delite was substantially lighter than Radian and had a threaded ring below push-up eyeguard to secure the eyeguard at desired height. This addressed annoying issues with loose Radians eyeguard. Of cause the main difference suppose to be inside. According to on-line wisdom Delite is based on Delos and not Radian. Scaled down Delos they say (whatever it means). I say it is scale up Plossl. The sliding eyeguard seems to be the same part as on Radian. Both made in Japan (Yay!). Same factory? Anyway, I can live with better version of Radian.

    Overall, ergonomics: A+. Very comfortable to use, compact and lightweight. Sharp field stop, convenient and effective eyeguard. Plenty of ER, and no issue with eye positioning, blackouts of kidney beaning.

    This night I tested 11mm Delite on Jupiter, Saturn and Mars side by side with BCO 10mm, SLV 12mm and ES82 11mm. They were neck to neck in sharpness, contrast and light scatter. I felt that Delite had a slight edge on planets over the rest, and ES82 was slightly behind the other three. Although, it could be because Delite is the new guy, and I was still subconsciously steaming about 55 deg thing of ES82.

    Anyway, all four are great on planets. If you wear glasses go for Delite or SLV, if not for BCO or ES82.

    For the faint stuff I tested the EPs on moons of Neptune and Uranus. After almost an hour I managed to detect only Triton of Neptune. At 13.8mag and ~16 separation from Neptune, it was formidable challenge for my 8 SCT. Once again (as with Pluto before) only BCO delivered.

    On crescent Moon all 4 EPs delivered as far as sharpness goes. Delite however was clear winner in overall experience, since it delivered largest FOV while comfortably observing with glasses on.

    Next time I will test Delite against other 3 EPs on faint galaxies in my 150R 6 F5 achro.

    I have an 18.2mm DeLite.



    They're nice EP's, very orthoscopic like I thought. They also Barlow and reduce well.



    I was surprised to find that they were made in Japan as well. I had a 7mm DeLite as well briefly but had to return it due to visible debris in the field of view. The replacement was the same so I returned that and ordered a 7mm Sky-Watcher UWA. Not quite the same but the Barsta made UWA is still fine and regularly used lol.

    Thanks Gabby and Ed. So far I have a very good feeling about Delite. Let's see how it will perform on faint fuzzes.

    Funny thing, I had to returned Barsta Flat Field because of the debris, but I would expect better from TV.

    BCOs are excellent EPs. I did so many comparisons and they consistently come on top of premium EPs 2-4x more expensive. If they come in more focal lengths and had a bit more eye relief, my EP case would be much smaller and lighter.

    Thanks Ed! You can always come up with good "justification". As with other new EP series I was waiting for the used market to stabilize in terms of price and availability. Recent $40 rebate seems to help both.
