  1. I am looking for a really good Barlow, that doesn't compromise the performance even of the greatest EP's. Speaking of good EP, I already have a 3.5mm Delos - "Barlowing it" puts any scope on its edge anyway. I intend to use it on my 90/600 APO and possibly a c11 in the not-so-far future. Any recommendations, which one to take? Right now, I am looking at the Powermate 2x. I see, it's a corrected optics, but is it also APOchromatic? Other, quite exotic piece I found and seems interesting, is the Baader Fluorit Flatfield Converter. Latter seems interesting for planetary photography too.
  2. Hello there My budget for eyepieces is $1,000. I started off thinking I would get a Celestron eyepiece kit for about $200, for example. After trying a few out, I soon realised that I wanted eyepieces of higher quality. My mindset is that I'm investing $2,000 in my telescope, a Celestron 9.25 SCT, and I want to be able to extract from that scope the very best views that I can. Wishlist - I'm looking to buy 3 eyepieces maximum (not including a Barlow) Ideally - if possible - I would like to get eyepieces that I can use on both my telescopes, but my priority is toward the 9.25" as that is the bigger investment. Both my telescopes have 1.25" barrels. * Cassie - A Celestron Newtonian. Aperture = 130mm, FL = 650mm, FR = f5 Max useable magnification between 250x and 307x * The Cubble Space Telescope - A Celestron SCT. Aperture = 235mm FL = 2350mm, FR = f10 Max useable magnification between 460x and 550x I don't feel comfortable spending more than about $300 on each eyepiece I want these eyepieces to last as long as possible. I try to look after thinbgs if I can. Decent eye relief if possible I will purchase a Barlow separately Field of view - something 60% + Usage - My observing will be probably 80% solar system planets & moon, 20% deeper sky objects I'm not that in atsrophotogarphy. I have a little Celestron NexImage 10 with which I am hoping to make some videos and stacked images of Jupiter, Saturn and detailed imaging of Pluto ( ) I really just want the WOW factor right now. Enjoying the thrill of Saturn;s rings, tracking Jupiter's 4 main moons, detailed lunar observing etc. Questions - So what would be your suggestions or advice, please? I have been looking at the Tele Vue Delos & Delite range. The Nagler range looks nice but I'm note sure if I need 82' field of view. A bit pricey, too. Explore Scientific's offerings are a possibilty. What's the deal with zoom eyepieces? Does that mean you can have an eyepiece that will do the job, for example, of a 6mm, 7mm, 8mm and 9mm eyepiece all in one? Is there a trade off?? What's the catch?? Regarding Barlows, I was thinking of just keeping it simple and getting a decent 2x lens without spending crazy money. Something in the $150 range. Or would I need a high end Barlow to complement the better eyepieces I am hoping for??? Overall, I'm looking for 2 or 3 eyepieces and 1 Barlow with a $1,000 budget. Any thoughts, ideas, advice or opinions all gratefully received, thank you.

  4. Mint, only taken out of box. Bought from Telescope House a few months ago. Paracorr 2 setting H £399 including Royal Mail next day, signed, tracked. Bank xfer or Paypal friends. Photos following....
  5. Unknown for me as eps. Which makes have best eye relief at any given fl. Being a Vixen fan, their 8-24 is on my radar, but are there others as easy?
  6. LNIB Minty Ethos 17mm - £390 I moved to the Nagler T4 range for more viewing comfort and this lovely eyepiece needs to find a new home. This is a LNIB eyepiece that saw limited focuser action 3 times as it was purchased and received on the 16th of September this year. Comes with original box, wrapping, sticker and caps. Any minor dust will be blown off with a manual blower prior to shipping. No scratches, no dings no falls, no nothing. Price includes PayPal fee and shipping with insurance and tracking. Thanks for looking! Clear skies, Nicos
  7. I have to admit I am lagging behind following the advancement in eyepiece-tech. Which would you prefer for planetary work with a 105/735 APO refractor and a c5? Delos 3.5mm or Vixen hr 2.5mm, or something else? The Delos would already yield a 200+magnification, I don't think it's too much use to stretch it further. Did anyone has/had a chance to compare these two?
  8. I use the TV Panoramic mount with my Genesis. Bought both together & they are excellent grab & go. So as my Skytee 2 is too heavy for tucking under an arm & I like scope in or on top mounts, I am considering a fork mount for my fracs, of which the 120 Equinox is bulkiest and heaviest. The only maker I can find for fork mounts for scopes (others for binoculars) is Tele Vue, & their Gibraltar 5. They seem to come with a star finder gadget which may be good being for TV. So does anyone here use a TV Gibraltar for any size of scope, & can advise on its pros & cons including the star finder?
  9. How good is this scope for rich/ flat field and reducing FC & CA? Much cheaper than Tele Vue equivalent.
  10. Looking for hen's teeth again. Anyone out there got a 26mm Nagler or 31mm Nagler they might part with?
  11. Hi. I have got myself an ED80 scope, and have been using the 28mm EP that came with it, but when trying to look at Saturn, it just looks like a bright dot. I would like to see it larger and in more clarity. On doing some hunting around I have read that the Tele Vue Nagler Zoom EP's are regarded as a good quality EP that will last. So the question is, will the 3-6mm EP or the 2-4mm nagler EP's be suitable for my ED80. I got this scope mainly for AP, but I am intersted in visual work as well, so eventually I may get a scope that is a dedicated visual scope, and hopefully the Nagler EP would suit that scope as well. Any advice would be great!
  12. Hi clever people (and fellow geeks), I live in London and I mostly do narrowband imaging from my roof. I have a 2005 tele vue NP-101. Its an F5.4 super apo. Its a great scope and it cost (with a few other bits) around £1800. Question: Would I be wise to sell it and instead buy a tele vue genesis? The Genesis isn't a super apo but I'm thinking that doesn't really matter for narrowband imaging and at f5 it is a bit faster which will help. As it is a petzval design I'm assuming it will have a nice flat field. I can get one for around £600... and I could use the money I've saved to buy pixinsight and other bits of astro kit. wotdoyathink?
  13. Tele Vue: Delos 10mm AFOV: 72º FL: 10mm Eye-Relief: 20mm Barrel: 1.25" Weight: 408g Length: more or less between 125mm - 140mm As soon as I looked through the Delos eyepiece, Saturn jumped onto my face. The breath whooshed out from my body and everything froze for a split second, as though the world and the ringed planet had come to some silent agreement and they paused for that tiny span of time of absolute wonderment. It was a fabulous effect, Saturn had been captured perfectly and for the following evenings I searched for that moment time and time again. Saturn was always going to be unbelievable and drew gasps from myself and non-observing girlfriend and even at this lowish magnification many subtle atmospheric bandings were clearly noticeable as were the six faint moons; tiny spheres of dimly sparkling light, beautifully contrasted in the eyepiece’s night of black velvet. Using the Delos as a backdrop against which to explore the joys and complexities of the past was turning out to be a joy. Under the stars, under the canopy of dark skies, it is a great eyepiece with which to understand and celebrate what matters to us in this hobby. On anything I decided to view the image was always outstanding, skipping from object to object there were nights when I didn’t need to bring out another eyepiece. Deep space is incredible and the Delos is perfect for detailing the matted starlight and glittering sphere of suns within many globular clusters, especially at this time of year around Hercules, Bootes and Coma Berenices, the dark background and wide-field only enhancing the globulars' brightness. In comparison with the 9mm Baader Genuine Ortho the difference was surprising. In the 10” f/5, the BGO 9mm has been the most used, the most celebrated and revered eyepiece whose outstanding performance on globular clusters, galaxies, planets and the Moon had driven me to buy the 10mm Delos in the first place. Image quality in both eyepieces is as sharp and crisp as it is going to get, yet I found the Delos offering a more neutral, significantly brighter and aesthetically pleasing view. The difference in AFOV and glass is simply staggering. During normal viewing, there came the stage where the Delos just disappeared, no longer peering through a peep hole but out of window on the side of some space craft. Galaxies in Virgo and Coma Berenices were a real telescopic treat, well defined stellar patches of soft light that with concentration often revealed more of their inner secrets. Beginning a tour at M 61, I began galaxy hopping, field of view by field of view along a cosmic stream of galaxies with their dense cores of billions and billions of stars. M 88 took on a faint, spiral affect while the bright M 104 was elongated, punctuated by a soft, stellar core appearing to be - but not clearly separated at this magnification of 125x - at the edge of a dark lane. This week the evenings have had the company of the waxing, waning and full-moon which brightened up the night sky and I figured would make quite a challenging condition for the Delos. Framed adequately within the AFOV, the eyepiece brought out sharp and crisp details across the entire Moon’s surface, giving it a three dimensional quality. As the Moon slowly drifted by it felt as if you were orbiting close above its surface. There was neither aberration nor flare and once out of sight, there was no evidence that the Moon was lurking just outside the FOV – except for the sky being brighter. The quality here was as good as any branded Ortho I’ve looked through. And even though the heart and mind are probably the true lens of stargazing, evening after evening, aberrations on any object was zero as far as I could tell, no curvatures, no astigmatism, nothing. The Delos 10mm is a medium power, wide-field show-piece where objects can slowly drift from one side of the FOV to the other without a hint of distortion or loss of resolution. Every object was just as perfect at the field stop as it was when on axis in the centre; no flare, no scattering of light, no ghosting, no elongation of stars at the edges. Physically, the Delos 10mm is large. It offers a 72º FOV, weighs in at about 408 grams and is about 140mm long when fully extended. Eye-relief is exceptionally comfortable at 20mm and the eye-lens is huge, giving a sense of augmented immersion while observing, especially after being accustomed to 40 to 60 degree eyepieces. As would be expected the Delos’ build quality and attention to detail is exquisite. At an angle in the light, the coatings give off a kind of purplish-burgundy frac like tint and peering into the eyepiece itself reveals complete darkness. The sliding mechanism is a technical wonder which is used to find your own exact eye-relief comfort. It seems to be essentially a metallic sleeve with locking rings incorporated to prevent any slipping but even when loose the eyepiece remains firmly in place until you physically slide it. There’s even an engraved scale to mentally note where you like the eyepiece’s position and if you decide you can lock the rings and everything remains solid. These rings also double as a nice grip when handling the EP, even when wearing gloves. There is something quite pleasant about having engraved green lettering in your eyepiece case, but as with all new technical wonders, it might be necessary to practice a while with the Delos until it becomes the perfect instrument for observation. Although there is certainly no kidney-beaning, at first, at odd moments, I found there was blackout which simply highlighted my own inexperience when dealing with an eyepiece of this type but with practice and careful adjustment of the eye-relief mechanism everything was righted in no time and whether you wear glasses or not, you will more than likely find your own eye-relief position that perfectly tunes itself to your own personal sweet spot for viewing. The Delos 10mm, then, is a majestic wide-field. It has excellent sharpness, outstanding eye-relief and is a beautifully built, high-contrast, ghost-free, flat-field, eyepiece. It is simply a joy to handle and optically superior to anything else I have ever used. However, there is one significant problem with an eyepiece like the Delos. Once used you cannot ever go back to the night before you owned one, because you were a different person then, and like Alice, you’ve gone through a looking glass and have entered a new world of visual wonder, opened up a celestial window onto the universe from which you can never return.
