  2. This listing is for a complete hydrogen-alpha solar telescope setup. My asking price is for the complete kit is £800. I would prefer not to sell these items separately, but would consider it. Included in the sale is: a Lunt LS50Tha H-alpha telescope with B400 blocking filter (pristine condition, mark free, clean optics and fully working order), Geoptik dovetail bar, Tele Vue Sol-Searcher solar finder, Official Lunt clamshell, Vanguard hardcase, Sky Watcher A-Z Pronto alt azimuth mount and tripod + extension, Tele Vue 11 mm plossl eyepiece, Tele Vue 15mm plossl eyepiece, Spare brand-new Lunt LS50 focuser (never used), Baader extension adapter to ensure a variety of eyepieces fit (currently fitted to the blocking filter), Original box (not shown in the photographs). Everything was purchased brand new by myself just over six months ago. This is a reluctant sale and I’m sure the purchaser will have many happy years of use out of this fantastic kit. I live in Hailsham, East Sussex, and request that these items are collected in person and paid for with cash please. If you have any questions, please do ask. Please find below some photographs of the telescope setup. Apologies for the image quality – they were taken on my phone.
  3. *Sale Pending* Hi Ralph, Tomorrow would be absolutely fine. I’ll wait for your PM. Rob
  4. ...This is still available for sale, but now reduced to £460 (cash on collection only please).
  5. Thank you for the offer, emadoussa. Regrettably, I am unable to deliver the telescope.
  6. Offered for sale is a Sky-Watcher 300p flextube 12” dobsonian telescope. All original parts are included (tools, eyepieces, 1.25” & 2” extensions, OTA caps and finderscope) as well as a light shroud and Telrad finder (in a hard case). The telescope and base are in superb cosmetic, mechanical and optical condition. The primary mirror is very clean and has produced some wonderful results. Everything has been stored inside the house to keep it dry. Shortly after purchasing this telescope, just over a year ago, I was diagnosed with a frozen shoulder (unrelated to using it). Therefore, I have only been able to use the dob a handful of times. With the new year approaching I think it’s time that this goes to a new home where it will receive some proper use! Asking price is £475 for cash on collection from Hailsham, East Sussex. Please find some photographs below:
  7. I am sure that I'm not alone in trying to complete a set of BGOs with somewhat limited success. The announcement of Kasai's new HC eyepiece, which looked pretty much identical to the Baader model, was news to my ears. I was particularly excited to see that Teleskop-express.de have started to stock them. However, looking on Kasai Trading's website today I see that there is a new announcement declaring this eyepiece line will not be continuing after all. Also, the product specific page has disappeared from their sitemap? http://www.kasai-trading.jp/notice.htm If I am reading this correctly, it is such sad news. This new eyepiece looked to be the only way we might get our hands on a 12mm or 9mm BGO equivalent in the foreseeable future. Even the Japanese volcano tops are becoming more difficult to find. I am left wondering whether there has been a dispute with Baader. Perhaps Kasai Trading has been forbidden from selling the HC line? I'm sure time will reveal the full story. I have copied below a text translation (thanks to good old Google) from the Kasai Trading website: ● The end of the project & Barrow reproduction eyepiece lens ● domestic With the closures of OEM domestic manufacturers, We have been pushing more aggressively than earlier this year, a project to reproduce at home the products handled by our supply has been stopped, for various reasons difficult to overcome, this project will cease I was forced to quit without obtain. It is up to you I feel very sorry for customers who folded more than anything, looking forward to the re-sale of the product to derail it in the middle of the road also, and regret extremely, I know you want the understanding humbly.※ This product is out of stock already famine, was being finished handling is as follows. All species HC-Or, AP-20mm, EWV-16mm, EWV-32mm, 2インチ2 × Barrow is in stock at this time ※, the product is scheduled to be completed as soon as the dearth handling is as follows. AP-5/7.5/10/12.5/15mm, short piece ball Barrow EWV-10mm, 3, 1.5 × species short Barrow 2 If you would like, is to get the product as soon as possible the above stock I would suggest. Please excuse the rather odd language generated by Google's translation (some of it is a little confusing), but you hopefully get the general idea. It is rather disappointing to think that this very fine eyepiece line may never be reproduced again. Clear skies to all, Rob
  8. I think it is worth starting with the old saying 'the best scope is the one you can use most regularly'. Both scope designs are very good for the money. However, there is a significant difference between their weight and portability. I have a Lightbridge and am a huge fan of its ability to collapse into a much smaller package. I can managing the 12 with no issue at all. I can also move the tube when it is fully built - should I wish to re-locate at speed. The flextube is, without question, far better out of the box. The Meade is a wonderful scope, but the do require so upgrades (then they really shine). Skywatcher scopes hold collimation well and usually have good springs etc. The lightbridge rocker is not quite as substantial and will require collimation each session due to the truss design. If you have not seen a 14 / 16 flextube in person you really should... they are HUGE! I was put off purchasing one after seeing a 400p. I am sure the views are fantastic but the rocker will not go through a conventional doorway (neither the 14 or 16 Skywatcher will). The Meade should be ok. As mentioned, the Meade will require a greater number of tweaks immediately. In addition to the usual bits (telrad, bobs knobs, etc) you would need to look at some sort of counter weight system - particularly if you plan to use heavier eyepieces such as the larger Naglers etc. I use taxi magnets on mine and then attach dumbbell weights as required. The flextube has a slightly better balancing point and is more friendly to heavier eyepieces. The views are probably very similar between the two 16s. In my opinion, the 14 is too close to a 12 to justify the significant difference in weight and size (I think only 33% more light?). I would have suggest having a good look at the lightbridge 12 and the flextube 300p too. Best regards, Rob

    hello from barry

    Welcome to SGL Barry.

    Hi John, Welcome to SGL! Wishing you clear skies. Rob
  11. Your decision whether to purchase 2" or 1.25" eyepieces depends on whether you are looking for wide field views and or how much you wish to see in the eyepiece. How much we see is, in part, determined by the field of view. There can be a significant difference in price between these eyepieces, but also their performance too. A cheaper 2" eyepiece can produce some vey disappointing results, whereas a 1.25" eyepiece of a similar power (such as a Baader Ortho design) never disappoints. For the moon, planets, globular clusters, double stars, etc you will be looking for greater magnification. I would recommend and eyepiece that is around 8mm for medium power viewing. This would result in views with 159x magnification, more than enough to see the planets well on most nights. For galaxies and nebula most observers use lower power (low magnification) eyepieces. Therefore, something around 24mm or greater would be preferred. This would result in a magnification 52x in your scope and would be perfect for M81 & M82, M31, the veil nebula, etc. Interestingly, If you look through a 40mm 1.25" eyepiece with a 42mm field of view, you will see more or less the same amount of sky as a 24mm 1.25" with a 62 degree field of view. This is because you see the same amount of sky with both, but one of them (the 40mm) presents the view in a much smaller size. If you look through a 22mm eyepiece with 82 degrees field of view, you will actually see slightly more sky than the 24mm 1.25" eyepiece. Another benefit is increased contrast when you view with slightly increased magnification. 2" eyepieces are more expensive because there is more glass required and a lot of design work to achieve a non distorted view. Ultimately, 2" eyepieces let you see more sky - in some cases, much more sky. When you look through a 2" eyepiece with 100 degrees field of view it is a bit like looking through a window from a space ship sometimes, but you pay a hefty price for this. My recommendation would be to consider Celestron's X-Cel LX eyepieces. They are very reasonably priced at around £70 each eyepiece. Perhaps just the 25mm and 8mm / 10mm to start. If you find you are looking for other sizes then you might add something in between, or with a little more power. It is very tempting to purchase a full set (at great expense) straight away, but you will find there are certain sizes you are always reaching for. Please find a link below: http://www.firstligh...x-eyepiece.html First Light Optics (the site's sponsor) are an excellent company and have never let me down. They would be my first call. However, Harrison Telescopes and Telescope House are also very fine companies. I have attached an image showing the different eyepiece sizes to that illustrates the amount of sky you would see with a 10" telescope (similar to yours). Regards, Rob
  12. Well, I am now a very happy owner of a Meade 12" Lightbridge. It arrived early this morning and was out of the boxes in no time at all. I was surprised to see that there have been a few updates made to the 12" Lightbridge, at least compared to ones I have read about online. Firstly, the trusses are now black, rather than silver. I was very pleased to see this, despite a sense of very mild frustration having purchased the black foam truss covers - I'll just have to double up! Meade have also updated the collimation and mirror locking screws to ones similar to Bob's Knobs. Sadly the springs are still terrible and I look forward to the new ones arriving in the post from Bob's Knobs. The focuser is nice a smooth with the fine adjustment having virtually no impact on OTA vibration. The azimuth bearing is also very smooth. All looks promising. The only negative is a typical Meade issue - quality control. Although a minor point, the felt has only been stuck to one side of the altitude bearings. Ed, at Harrison Telescopes, has spoken to Meade already about this on my behalf. It's certainly not his fault, but it is frustrating that Meade aren't checking for details like this before telescopes leave the factory. Thte Lightbridge is quite a lot larger than the Skywatcher 250px dob it replaces. Although, all credit to Skywatcher -the 250px is far better balanced. I have made up a basic counter weight system for the Lightbridge and will have to bulk order some more taxi magnates as a more permanent solution. After a few tests I have worked out that I will need around 2.5=3kg of counter weight to balance the 31 Nagler, light shroud and a Telrad. I have attached a photo of the 250px and 12" Lightbridge to illustrate the size difference. Looking at the Met Office's site there may even be a bit of clear sky tomorrow evening... this would, perhaps, be a first - to actually be able to use a new scope on the same weekend it arrived would surely be madness! Regards, Rob
