  1. Got some info on the Astro-Professional 130 triplet. Now I know why it's going to be £800.00 more than the Meade 127. While it is FPL-51 the most important thing is that the optics are totally Japanese made using Ohara glass. The mechanical parts are sourced from China, but everything is assembled and tested in Germany. It will also come with a 3" crayford focuser. So, Japanese optics and proper quality control.....looks very interesting. There will also be a magazine review of the scope coming out fairly soon. John
  2. Congratulations ! You made the right decision in the end. Should be a great starter scope but also good enough to not outgrow for quite a while. John Dare I mention eyepieces and accessories
  3. Just out of curiosity do you know if the scope was shipped direct from the supplier to you or from the dealer. John
  4. Sorry if that particular post mislead you. Still for the money the new 16mm isn't bad value ($269 in the US), sort of a Hyperion level of performance but with a 100 degree FOV. John
  5. Don't forget the William Optics SPL eyepieces. As good optically if not better for planetary use as the Uwans / Nirvanas but with a 55 degree FOV and 20mm eye relief. John
  6. That's a different eyepiece entirely (the Explore Scientific 14mm) and not related at all to the 16mm 100 degree one mentioned in the original post in this thread. John
  7. For £129.00 you could get a new Nirvana 16mm 82 degree eyepiece from FLO which is very similar to the 16mm Nagler in performance. John
  8. I've asked someone to find out what they can about the Astro-Professional version. ie: glass type etc. So hopefully I'll have some details shortly. I'm guessing it should sell for about £2,100.00 in the UK. At nearly a grand more than the Meade 127 that should buy much better optics and quality control. John
  9. I'm waiting to see what happens when the new 130 APO triplets arrive. Much higher spec than the Meade 127 etc. although about £1,000.00 more. Will they push down the price of the various 127 triplet ed scopes to the £999.00 price point? John
  10. I find that with my SkyWatcher 10" dob I can use about 240x for planetary most nights and on lunar 400x. With my OO UK 14" dob with it's 99 Strehl mirror I would normally use about 400x for planetary and about 550x for lunar (on a good night up to 800x). Premium optics and aperture mean you can really push the magnification. I live just about in the dead centre of the UK so light pollution isn't as bad as London but it's still not that good. John
  11. The new 130 APO triplets are about to hit the market at just over £2,000.00 from several brands. Astro Professional TRIPLET APO 130/910mm http://www.teleskop-express.de/shop/product_info.php/language/de/info/p3279_Astro-Professional-Triplet-APO-130-910mm---3--Crayford-Auszug.html More expensive but a step up from the FPL-51 127 ED triplets. It'll be interesting see how well they perform. John
  12. If you missed this one on the National Geographic channel when it was first broadcast a little while ago it's being repeated this Thursday night at 8:00 pm. " The LBT telescope sits on a mountain in Arizona, over 3,000 metres above sea level. Like a giant pair of eyes, it stares up into the night sky. Equipped with two giant mirrors, it allows astronomers to see further into space than ever before. Capable of producing images of heavenly bodies with startling clarity, the LBT focuses its two giant mirrors on stars tens of millions of light years away from Earth. It stands on the shoulders of historic engineering achievements that have allowed it to see so far. Find out how this magnificent instrument was made possible through a series of engineering breakthroughs. Big, Bigger, Biggest discovers how six landmark telescopes contributed innovations towards its development, allowing astronomers to see ever deeper into space. " John
  13. I notice that the ES100 14mm is now stocked by AstroShop.eu price Euro 439.00 http://www.astroshop.eu/explore-scientific/p,17007?sid=493b0379fa7e27cfc0c75c73e1b69ce6 John
  14. The eyepiece is available under both TMB and Zhumell brands.Telescopes.com is selling it for $269.98 Quote: Brand new from Zhumell. The all new Z100 series eyepieces offer a value priced 100 Degree AFOV telescope eyepiece. Once word hit the street of this new eyepiece - all the skeptics starting talking. Well, if you want to spend half your paycheck on an eyepiece - the other 100 Degree eyepieces are VERY nice, but if spending that much on an eyepiece is hard to swallow, but you want the 100 Degree experience, the all new Z100 eyepieces are a great buy. http://www.telescopes.com/telescope-eyepieces/2-inch-eyepieces/zhumellz10016mmeyepiece.cfm Discusion on Cloudy Nights http://www.cloudynights.com/ubbthreads/showflat.php/Cat/0/Number/3408560/page/0/view/collapsed/sb/5/o/all/fpart/1/vc/1 John PS Reading the Cloudy Nights discussion they seem to be similar to Baader Hyperions in optical quality. In other words good but not premium quality. They have nothing in common with ES100 eyepieces except for the 100 degree FOV.
  15. Here's a quote from Al Nagler that may help. "You didn't say what type of scope you have. If you called Tele Vue, We would have recommended the Big Barlow if you have a Newtonian, and the powermate if you have a refractor. The reason?, For the Nagler eyepieces the optical benefits of the powermate are invisible, however, ergonomically in a Newtonian both the BB and powermate will reach their parfocal point. In a refractor, where a diagonal is used, the BB will not come close to reaching it's parfocal point, and an inch or so of in-travel will be required. " John
  16. Do remember that this applies to goods bought online (distance selling) and if you buy in the shop your rights are more limited. Also there are some exceptions (custom made etc.) that can affect your right to return even goods bought online. But it's so much better to talk to the dealer first and explain your dilemma and let them help you to sort it out. John
  17. Just ordered an 8mm Ethos from them while the sale is on. I've just sold my 17mm Ethos and so had the cash to spare. So now I have the 6mm, 8mm and 10mm Ethos eyepieces. For me it's worked out that I prefer the Ethos at the shorter focal lengths, but like the Naglers better at the longer focal lengths. The 17E just wasn't being used, I seemed to reach for the 26mm Nagler every time instead. Every-one's eyes are different so what's best for one person might be very different for the next one. Colour sensitivity, coma sensitivity, astigmatism, visual acuity, eyeglass wearer etc. all play their part. I find the Naglers for instance very easy to look through, and for me they have plenty of eye relief and have zero problems with black out. It's a pity that you can't try some out and see what's best for you. Although I suppose you could find a dealer that would let you return one if it didn't suit and exchange for the other brand perhaps. John
  18. OO does CNC tube rings to fit, but very pricey. Stayfocused also does CNC rings to fit: http://www.stayfocused.co.uk/index.php?act=viewCat&catId=14 John
  19. The one thing I can definitely say on the subject is that you can't go wrong in choosing either the Pentax or Nagler. They're both great eyepieces. Everyone's eyes differ in their sensitivity to colour so while some say the Naglers have a much warmer tone many may not really notice much of a difference. And if you use filters it doesn't matter anyway. They both have distortion, just different kinds. Naglers are optimized for astro use and have sacrificed some pincushion distortion in exchange for improving other aspects of the eyepieces. Pentax were designed for use with spotting scopes and in turn have sacrificed some rectilinear distortion in exchange for improving performance in daylight while panning horizontally. The Televue barlows and Powermates are excellent. I came across a quote from Al Nagler that said for newts/dobs the barlow was just as good as the powermate, but that with refractors the Powermates had a clear advantage (something to do with being used with a diagonal). UK prices on Pentax do vay a lot. For example UK prices on the Pentax 30 XW vary between £420.00 and £529.00 so there's a lot of checking to be done before saying that it's going to be cheaper to import. Also on Naglers Telescope House regularily has 10% off sales. John
  20. I second that. Temporary cables are just that TEMPORARY. I used the right equipment at both ends from where it leaves the garage to were it comes into the shed (proper sockets etc.) and ran the cable behind some bushes against the fence. The SWA cable is very stiff and awkward to handle but it's the proper stuff for the job. John
  21. I replaced the extension cable out to my shed with a permanent one made from SWA armoured cable rated at 31 amps. A bit over the top perhaps, but it is designed for outdoor use (can be buried with no other protection needed) and it will handle far more load than I'll ever need. John
  22. One other scope that would make a great guidescope is the Star Sky 90. A lightweight achro at 1.9 Kg and comes with a crayford focuser and retractable dewshield. Decent sharp optics as well and only £149.00. Not as good as the WO or Equinox but much better than the Startravel 80.and considering the price it's a good deal. http://www.opticstar.com/Run/Astronomy/Astro-Telescopes-Ascension.asp?p=0_10_1_6_110 John
  23. Came across this recently. The title's a bit misleading as it actually covers how Barlow and Smyth lenses are used with various eyepiece designs (Naglers, Powermates etc.). Very readable with plenty of illustrations and written in mostly plain English. http://www.brayebrookobservatory.org/BrayObsWebSite/HOMEPAGE/forum/Smyth-Barlow%20lenses.html John
  24. Another scope worth considering, and within your budget is the Skywatcher Heritage 130p Flextube at £125.00 from FLO. http://www.firstlightoptics.com/proddetail.php?prod=Heritage_130P&cat=31 Decent optics and very compact when stored away. John
  25. Any of them would be very good, but the refrators's shorter cooldown time would sway me in the direction of one of the refractors. While the Celestron Omni XLT 120 is a great buy at the moment I still would go with the TAL. Of course if portability is important then one of the Maks would be good. You'd just have to allow for the longer cooldown time. Although it's a lot more what I would go for if I had the cash to spare would be the Antares 105mm / 1500mm focal length refractor.
