    Check out THe HAARP project nikola Tesla got their first .But in alaska Robert eastlunds project seeks to heat portions of the ionosphere purpose research haarp stands for high frequency active auroral research programme ? ! Along the lines of the previous post ? check out the patent Weather modification is one possible application among many others ! Conspiracy theory ? ! pumping millions of watts of energy into the upper atmosphere with impunity can’t be a good thing can it ? Im all for advancing technology , but not at all costs , and which puts our health and lives at risk ! As nick begich said and was the title of his 1995 book. ANGELS Don’t PLAY THIS HAARP !!

    It’s a very long list ! And personal to each and evryone of us ! My interest in astronomy started aged 8 i picked up a book on a shelf in our scout hut i was a cubscout aged 8 the book are rare 1st edition of the story of the heavens by sir robert ball hand painted illustrations of all of the best celestial objects which when many years later observed directly matched the illustrations or exeded them ! These days hi res hubble pictures images etc may disappoint the current newbie or younger generation as the direct visual view dosen’t look like or live up to said images or hype ! My avatar nickola tesla electrical genius visionary inventor of our modern electric centred world where would the stargazers lounge and any of us be today without steve jobs or bill gates ? Worthy avatars ?! Growing up in the 1960’s 1970’s one small late night progamme fired my imagination The sky at night well past my bedtime but allowed ! patrick moore another worthy avitar Donald campbell pushed his bluebird k7 across coniston water in 1966 /67 at speeds faster than a bugatti veyron does today on stable flat tarmac ! All of our lives are formed and shaped in many different ways but the common thread is that we have all got into astronomy in many different ways down many different paths ,but have come to enthuse over it /love it for many different reasons ,but this is the avatar we all have in common !

    Rag and bone man

    Rag and bone man ! very much of its time ! i.e. Steptoe and son ! These days such bin diving ( lovejoy) escapades are very much in fashion ! its called repurposing / recycling / reinventing / repurposing ! but the bottom line is which ever decade your from / in its about making something from nothing ! The atm spirit lives on

    The Perfect Telescope??

    If it's a vintage one it will have an RAS Thread then sacre bleu can't be vintage it dosen't have a cork ! but as a scope the cork gasket in the lens cell fits the bill ! has a modern innovation a liquid lens which if you pour it out of the scope and consume it .The view through it gets better and better from alco- chromatic to alpochromatic hic ! And once poured into a glass said liquid lens if spun at the correct rate will form a parabolic reflective surface so two scopes in one happy days !

    Lovely looking old scope on ebay

    The tube assembly and mount are AE OPTICS jim and rob hysom the pedestal and alloy legs are fullerscopes ? !! old school but nice !
  7. I have a nagler 11 mm type 1 rare ish ?
  8. the proof of system performance is clear when you talk to observers who have had the opportunity of using a refractor of even moderatley good figure this has been discussed with many visual observers including professional astronomers The views of the late david sinden former grubb parsons cheif optician are appropriate .David said that the cleanest most detailed and highest contrast images he had ever seen were through two optical systems an astrophysics 7 inch starfire refractor and a macksutov of his own design with a 14% obstruction david had of course made and used some of the worlds largest telescopes . supplied nasa and professional observatories high accuracy optics for decades.
  9. You don't have an eyepiece obsession until you have every eyepiece brand from 2.5mm to 55mm ie the whole range in between on all of the high end brands of eyepieces .I would say you have a mild interest in eyepieces
  10. so To go with the astrophysics 180 EDT Eyepieces televue radian 3.5mm nagler 4.8mm type 1 7mm nagler type 1 9mm nagler type 1 11mm nagler type 1 13mm nagler type 1 15 mm panoptic 20 mm nagler type 2 22 mm panoptic 35 mm panoptic also circle t japan orthoscoptics 4 mm 5mm 7 mm 9 mm 12.5 mm 18 mm 25 mm 40 mm televue nj japan diagonal astrophysics did not supply one at this time some of these are doubled up to go with a denkmier 2 binoviewer i will post up some pics in due course
  11. mine cost £ 3850 gbp ota mount £ 2650 gbp in 1994
  12. Hi stu i'll post up some pics eventually weather work etc !
  13. Hi I have an astrophysics 180 EDT F9 refractor Delivered in june 1994 with an astrophysics 1200 Qmd equatorial mount see the company seven page link it gives you an idea of the potential and performance of this instrument . http://www.company7.com/astrophy/refractors/180sf.html At the time it was the best triplet apochromatic refractor fast forward 23 years ! obviously it has competition .I would still put it up against the best modern eqivalent mr r christian can figure an objective to near perfection ! like no other, it's only a seven inch but it's outperformed many a larger scope on many nights ,though my view is apeture wins ,i think that sometimes you get a more asthetically more pleasing view on most observing nights with the astrophysics ,and i have some reflectors with highly accurate optics and large apeture,seeing often defeats the bigger apeture asthetically larger can offer more detail and a brighter image .Not logical largely subjective but the view is that the astrophysics often outperforms my larger scopes a lot of the time to my eyes at least .It bears high magnification well and the views in good seeing are razor sharp ,the moons terminator is a good and often breath taking experience as are planetary views. They are however not magic telescopes ,even roland christian tells prospective customers ,don't wait for me it's likely that i won't be able to make a telescope for you ever ,but there are a few manufacturers out there that make telescopes that are as good ? they don't have the qudos or mistique of an astrophysics or the secondhand resale value !! for the record i would not pay secondhand what my telescope is allegedly worth these days !! I think it's a great telescope hence why i still have it after 23 years still looks and performs like new ,i look after it ! tec takahashi apm /losz and even some chinese manufacturers make some good apochromatic triplet refractors . would i trade mine for one er no !!
  14. Hi I have a 12 inch ae optics mirror with a hilux coating 12 years old still looks ok ! That said i have a fullerscopes 10 inch david hinds mirror from 1976 that hasn't been re -coated looks good probably not as reflective as new but looks new and works well to date !! respect

    SUPERSCOPES domes

    Hi peter If you pm me I can give you some information ,I used to work for them for a time instralling observatories ,them in the singular sense ,in that superscopes was phillip stone from Bedfordshire, I also have a superscopes observatory which I assembled in 1999 still works perfectly after all this time very well engineered ,phil stone was /is a clever and talented engineer. regards clive
