  1. Hi, I'm looking for a Panaview wide angle eye piece. 32 or 38mm. Willing to pay up to £50 or would consider swapping Canon 1000d. Thanks Simon
  2. As part of my equipment reduction, I'm selling the following items: Vixen HR 3.4mm (like new) £200 Vixen HR 2.4mm (like new) £200 1.25" Lunt Herschel Wedge (prism, ND filter, and wedge housing structure like new. Locking screw requires tapping and threading. Hence the discount) £80 SOLD The Vixen HR are the best eyepieces I have ever owned. A few members on CN matched them with the Pentax XO. No light scattering and incredibly sharp. In my opinion colour tone is neutral and sits in between the Docter UWA and my Zeiss Zoom eyepieces. Eye relief is comfortable if spectacles are not used (which should not at high magnification). The Lunt Herschel Wedge is an excellent tool for white light solar observing using a refractor. It works even better when combined with a Baader solar continuum filter in my opinion. The hole of the locking screw of the solar wedge requires tapping/threading. Apart from that, everything is in excellent conditions, essentially indistinguishable from new items. Caps and boxes (hard case for the wedge) are included, of course. Price includes 1st class RM signed-for. Payment via PayPal (as friends) or bank transfer. Collection from Cambridge also available if preferred. Thanks for looking, Piero
  3. I thought my eyepiece collection was complete until I bought my "last ever" telescope. This operates at a native F8 and is just over 3250mm fl. I have the longer Naglers, 31, 26, 22, 17 etc and 35mm, 27mm Panoptics. I was always a little disappointed with the kidney-beaning in the Naglers in other telescopes, though they were overall better than any other eyepiece I have used, but in this one they seem to be affected less and even the 26mm is now a keeper. Before I got the Naglers (over many years all s/h) I had 35, 27 and 19 Panoptics. These were my favorite eyepieces until the Naglers came along. I kept the 35mm as stars seemed a little sharper in the inner 50 degrees than the Naglers, but trailed off in the outer regions and the 27mm as it really is an exceptional eyepiece. In any case I often wanted to darken the sky with higher magnification so the longest ones were primarily used for sweeping and finding. Given sky brightness is becoming more of an issue I thought I would never need a longer focal length. Now the Naglers seem sharper over the entire view and with the higher magnification of a longer scope the sky is darker and I hanker after the widest possible field. The issue is that the 82 degree 31mm Nagler gives me a true fov of 0.78 degrees and the 35 mm Panoptic 0.73 degrees. There is noticeably more sky in the 31mm Nagler. A 41mm Panoptic will yield 0.85 degrees, an improvement of nearly 10% over the Nagler 31. As I can readily see the difference in the amount of sky covered by the 31mm Nagler and the 35mm Panoptic I believe the time to look at a 41mm Panoptic is here. Before going into a debate on whether ES eyepieces could fill the slot all I can say is that having been able to compare my old Naglers with new 82 degree ES ones in my scopes I and convinced that, for me, there is a small improvement with the Naglers at the outer regions of the field and so I am minded to discount them. They are fantastic value and I won't deny they are very good eyepieces. The 41mm Panoptic would seem fit the bill for this long fl scope though I suspect it would be a disaster in a fast Newtonian, which I also have. My quest is to find someone willing to part with theirs and/or suggestions of an alternative that someone has used in practice. Thankyou for reading Ian B
  4. Hi there! I’m looking forward towards purchasing a new wide FOV eyepiece from FLO (first light Optics ) and I do to know which one to pick! i will be using it on my f/6 8” Skywatcher dob and hoping to get good views of the Orion’s nebula , (large nebulae in general) andromeda and others. I ve heard the panaview 32mm is a good choice but I d like to know about the other options as well. I would like the budget to be around 100€ Clear skies, Kronos.
  5. Hello everyone, Bit of a backround: I've been a keen stargazer when in my teenage years, then couldn't pursuit my passion, but recently, in my forties, it hit me again, as I moved and life is good (South facing large garden, obstructed only from the North by our house, but then I just move the scope further and viola!). Started with 90mm refractor, but was always thinking of reflector. Long story short, I've got my SkyWatcher Star Discovery 150P GOTO a week ago. Bought it second hand, very good condition, and good mirror. Have got two nights stargazing, cought cold and I AM LOVING IT. Now I would like to get me a nice wide angle ep for DSO spotting. The scope is 150mm / 750mm f5. I've done some reading obviously, and Explore Scientific 82 degree series have all good reviews and fit within my budget. I can afford only one, and apparently the best for DSOs is the one that gives 2mm exit pupil. Now, for my scope that would be 10mm piece, and that is not within ES 82 degree range, so it's down to 11mm (2.2mm exit pupil) or 8.8mm (1.76mm exit pupil). My question is: which one would be better for my rediscovered passion? I'm gonna be using that ep for faint mostly. Thanks to everyone in advance for any kind advise.
  6. Selling this 32mm TV plossl with smooth barrel and TV eyeguard extender. It comes with lens caps and box. The box is rather ruined, but the eyepiece is in very good condition. Lenses are mint, 2 or three dots on the barrel. Asking for £100, which includes RM 1st class signed-for. Payment via bank transfer or PayPal as friends.
  7. I am considering this eyepiece for my refractors. It would be used with and without Baader barlow 2.25x. Has anybody tried this combo? In the past I tried the BCO 10mm, but I let it go.
  8. Selling some accessories. A couple of Meade DS 4000 Super Plossls, 9.7mm and 26mm. Both in bolt cases and in great condition. £15 each or £25 for the pair. Skywatcher 6x30 finderscope with caps and mount. Some scuff marks on the mount foot, as to be expected. Optics nice and clean. £17. Postage at cost.
  9. Hi everyone! I have a Celestron Astromaster 114 eq (114/1000mm), and I do use it whenever I can, but I'm still quite the newbie when it comes to observing. My point is, I'd like to observe the planets, but I dont't think the standard eyepieces that came with my telescope (10 mm and 20 mm) are powerful enough for that. For reference, the "furthest" I could see were the rings of Saturn , but they were very small and faint too. Are there any specific eyepieces you could recommend? :) And of course, any tipps and advice are also very much appreciated. Thanks, Sophie.
  10. Looking for my first televue eyepiece 25mm 1.25" barrel plossl, happy with used as long as great quality, bank transfer preferred payment Sorry, can't stretch to other Televue models
  11. Hi, I have a skywatcher 200p dob and was hoping someone would be able to recommend an eyepiece with a wide field of view that would help finding objects and observing larger objects like the Pleiades. I have had a look at an explore scientific 30mm with 82° FOV, but was unsure if it would be good with my scope. Thanks Katie
  12. Hello. True beginner given an Orion Skyquest XT8 (1200mm focal length; f5.9). I have had to collimate (all sorts of fun that was) as the scope had been moved quite a bit over time. Believe I have it very near perfect but will star test. Scope came with an Orion 25mm Plossl eyepiece so I am exploring what range of additional eyepieces I would like. From what I’ve read this scope is capable of a theoretical 400x magnification. Again in theory that would take me to 3mm as limit of eyepiece. But then I read about exit pupil limitations and scratching my newbie head. The majority of what I see suggests .7mm exit pupil minimum...? But it appears I would need to buy a much larger eyepiece focal length to avoid too small exit pupil. I wear eye glasses so would be buying longer eye relief pieces in case that is relevant. Advice truly welcome. Neill
  13. Hey, whenever I clean my eyepieces or filters, theres always a mark left from the cleaning tissue. What am I doing wrong or is this normal? Also, Im using optical grade tissue paper. Is it better to use a microfiber cloth? Thanks for the advice.
  14. Hi all I am putting together an oil-bath auto-collimator rig to check over my reflectors. It occurred to me to use an off-axis guider body and its pick-off prism to feed the light source in - no heath robinson pipe assembling. Then I can just use a positive eyepiece where the camera should go to examine the ronchi lines to estimate the optics quality. This raises the question - I would need to put the ronchi screen on the telescope side of the prism - say in a filter mount . Is this too far from the source ? Is the source to ronchi screen distance important ? Cheers Mike
  15. Hi everyone! My telescope came with 2 eyepieces, a super 25mm and a super 10mm. The other day I was looking at the moon (using my super 25mm and a x2 Barlow as always) and I decided to swap round my super 25mm to my super 10mm and it was a much better image! I could see right into the surface and view the craters inside the craters! Can someone please explain why the smaller diameter eyepiece works better? Thanks
  16. It's been a week since Christmas. How about some reports on new eyepieces received as gifts (or bought for yourself)? To get things started, I received a 17mm ES-92 and have had a couple of chances to use it in both a coma corrected dob and a flat field short tube refractor. It's easy to use with eyeglasses, has a very wide field of view that can be seen all at once without straining, is as sharp at the edge as a Delos (which is to say as sharp as at the center), has no discernable field curvature, and seems to have nearly constant angular magnification across the field. The weight and size do have to be managed, but it is well worth the effort. I haven't tried it without coma correction or flat field correction or with a barlow yet, so no reports on those aspects yet. I measured the AFOV to be 92 or 93 degrees as claimed using reverse projection with a flashlight shining into the field lens. Usable eye relief was measured to be 17mm using the same technique, so just a millimeter less than my measured 18mm for the 10mm Delos. Overall, I'm so stoked, I hope to get the 12mm and other focal lengths as they become available.
  17. Offered for sale is a Meade 5000 series 60 degree 9mm plossl eyepiece in excellent optical and cosmetic condition with original caps and box (sorry about the poor picture, but you get the idea). This line doesn't get the best reviews, but for a number of years this was my best high power eyepiece and is very good on axis. Personally I think that Meade were pushing it a bit at 60 degrees. If you treat this eyepiece as a normal plossl (with tight eye relief and a twist up eye guard that I have used) it's well built and optically better than the average. I've seen some nice Jovian detail with it, but once a 9mm Vixen SLV and recently Baader Morpheus made their appearance this eyepiece isn't getting much use and it's time to move it on. The price is £30 including postage and packaging within the UK. Payment by PayPal or cash on collection please. Please feel free to contact me with any questions. James
  18. Hi. I am new to astrophotography and want to start using an eyepiece camera with my Celestron eq130. Can anyone recommend a decent camera for a small budget, say £50. Also, do these type of cameras just fit into the telescope, or do they fit into a Barlow lens ??
  19. Celestron Luminos 82° 15mm Baader Hyperion 21mm. Celestron Luminos 82° 15mm eyepiece in mint condition -boxed - £50 -SOLD Baader Hyperion 1.25" 21mm eyepiece, never used, (I now have a nagler 22, while waiting for a clear sky) mint and boxed -£50 -SOLD Collection, or add £5 for postage per item. (also on ABS)
  20. Hi everyone, I just bought my first telescope, a Celestron NexStar C8, and have been having a wonderful time learning to use it. I bought it used, and it came with enough accessories to get me going. However, I have recently been searching for nebula filters, and have learned a lot about both filters and eyepieces from reading through the forums. My question is this: My scope came with a set of eyepieces (the Celestron eyepiece case, 1.5") and a couple others that are 1.5" as well. As I began researching eyepieces, I see that it is common to have 2" sizes as well. Would my scope accommodate a 2" eyepiece? If so, are there any benefits to me using a larger eyepiece? The 1.5" filters and eyepieces are a little less pricey, but if I can increase my scope's performance through using 2" eyepieces I will strongly consider doing so. Thanks for any and all info!
  21. I've upgraded to a set of BST starguider eyepieces so I have the following HR Eyepieces for sale. All in excellent condition, £20 each plus postage 25mm, 9mm, 5mm
  22. I Just bought a celestron astromaster 130EQ and I am still getting used to star hopping plus the red dot star pointer is a bit annoying. Will it be beneficial to invest in a 40mm eyepiece to make star hopping easier ? Will the larger field of view provided by the 40mm eyepiece be worthwhile ?
  23. Hi all, I'm looking at buying a Skyliner 200p scope second-hand, but it doesn't included a mount or eyepieces. Is it possible to: - Pair this scope with reasonably a priced mount (<£100) or even a tripod used for birdwatching (do you need a specific mount for this scope?) - Get an OK set of eyepieces (<£50) used for seeing planets and some beginner DSO. - Advise me on a telescope mount and eyepieces compatible with the Skyliner 200p for the prices stated above. The reason i'm asking is because my funds are limited ATM, so i'd like to buy a decent telescope with the intention of upgrading its accessories as funds permit and my astronomical knowledge advances. Any advice would be greatly appreciated.
  24. Thanks to recommendations from this forum, I recently purchased a Bresser AR-102s/600 refractor. (I apologise for the rubbish weather lately, it is obviously my fault. ) The supplied (1.25in) diagonal is very cheap, all-plastic construction. Even the barrels. And I would like to upgrade as soon as possible. This telescope accepts 2" accessories, so I want to begin by getting a decent diagonal, then upgrade eyepieces later. I had my eye on a William Optics 2" Dielectric Diagonal, but then saw an Altair Quartz Dielectric Diagonal 2" Push-fit for almost half the price. Altair also make a 2" Lightwave Premium Dielectric Diagonal, which falls roughly in the middle of the price range. I've heard very good things about the Williams Optics diagonal. My question is what are the Altair like. And is it worth spending the extra, for what is a relatively "budget" range OTA? Recommendations for 2" eypieces that I should consider are also welcome. Thanks.
  25. I have been reading that my 25mm 8SE Celestron eyepeice may not be very good in a Skywatcher 150P, and the supplied 10mm and 25mm are going to be average at best. I've also been reading that 4mm or 5mm is usable in the 150P, BST or TMB Planetary are names that seem to crop up a lot, but then someone mentioned Celestron X-Cel LX. I have not upgraded my standard 8SE 25mm yet so could certainly consider doing that, but would mostly like to get a nice high magnification eyepiece to go with the 150P which should be arriving at my door any minute now. Would the 5mm X-Cel LX be a good choice? What would be a good matching barlow to use with the 150P (and 8SE, if possible)? The only barlow I own is the one that came with the ST80, so, yeah.. Thank you.
