  1. 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.
  2. 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.
  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. 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.
  5. 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.
  6. Hi Everyone I need some eyepiece recommendations. I currently own a set of Meade Series 4000 UWA and SWA eyepieces. These are my pride and joy and are awesome eyepieces. Much better than the new Series 5000 range. I've not been keeping up with equipment news and reviews for a few years as I prefer my current eyepieces. However, I'm getting back into public observing events and was hoping you could recommend good UWA eyepieces that won't break the bank. I can't afford Televue and I wouldn't want to use works of art such as Televue or my Meade eyepieces for public use. What are the current good Ultra Wide Angle eyepiece offerings? What should I look out for and what should I avoid? Cheers
  7. 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
  8. Hey guys!i need to make this quick! I want to get a new 6mm eyepiece.I have a 8" f6 dob and i want to get a nice 200 mag and put the telescope to its limits at 400x The most i ve seen with is 240x for Jupiter and Saturn .i ve heard they looked stunning at 400x and i am keen on trying it.Ive got my eyes on a 6mm Skywatcher UWA eyepiece.and i have a Bst Starguider 2z Barlow lens.And i seem to be having problems with my 8mm Bst Starguider (300x in total).the bst has a 16mm eye relief and a 21mm lens diameter,but when i barlowed it and look at the moon yesterday,it was hard finding the right spot to look through the eyepiece and when i moved the image disappeared.I dont know if it will have that effect on planets,when I looked at mars it was fine but i definitely want to avoid that from happening again.Will it happen? The Skywatcher eyepiece i want to buy has a 16mm eye relief too.I dont want to make the same mistake now , i want a 6mm eyepiece at the price range of 50-70 euro either from flo or amazonuk.If the Skywatcher will have similar results,can you suggest another one?
  9. 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
  10. 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
  11. 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
  12. 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.
  13. 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.
  14. 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.
  15. 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
  16. 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.
  17. 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 ??
  18. 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
  19. Hi all, not sure if this is the right place for this, but cannot decide which is the better one.. Here is my problem; I have an old Telephoto lens that is an 86mm achromatic and has a variable focal length of 600 to 1300mm. I have had this years and don't really use it anymore, it's no good for astrophotography as it stands but after some experimenting with various eyepieces jerry rigged in the end of the lens I have found it makes a very good and effective refractor telescope...and as I want a larger finder/secondary scope on my LX90 this would seem to be a good use for old equipment. The lens has a 42mmx0.75mm male thread on the end for the attachment of camera adapters. I have had a look for a female threaded adapter that would allow the use of either a single or interchangeable eyepieces on the lens. Does anyone know of any such adapter, or perhaps a couple of adapters that would allow the end game I want... Thanks everyone. Jim
  20. Hey. Got a new 12 inch reflector and it takes 2 inch eyepieces. I have a 26 mm and a 32mm on their way. However, what would be the lowest useable eyepiece for it? Focal length is 1600mm (f/5.3). For example, revelation go down to 50mm, would this be of a use, or not? Also, what about going above 20mm, say a 15mm? Thanks.
  21. 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.

  23. 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!
  24. 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
  25. 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 ?
