couleurblue Posted January 3, 2010 Share Posted January 3, 2010 Does anyone know anything about SET-optics? There is what appears to be a super large ap. refractor in a carbon fiber body on e bay at the moment. or Link to comment Share on other sites More sharing options...

dweller25 Posted January 3, 2010 Share Posted January 3, 2010 Personally I would spend my £2250 on something with a known pedigree. Even the best manufacturers have QC problems. Link to comment Share on other sites More sharing options...
harry page Posted January 3, 2010 Share Posted January 3, 2010 HiI have been talking to this chap and are going to visit him and see his scopes .I will let you know what I learnHarry Link to comment Share on other sites More sharing options...
Takahashi Posted January 3, 2010 Share Posted January 3, 2010 That's the same guy who was selling that huge home-built 6" f15 refractor a while back :6" F15 Refractor, this will cause queues at StarParties on eBay (end time 24-Nov-09 20:00:42 GMT) Link to comment Share on other sites More sharing options...
MishMich Posted January 3, 2010 Share Posted January 3, 2010 This person makes these and sells them on eBay. There a couple of people trying to do this, and I have met one of them. I understand about buying scopes with known pedigree - but if people only do that, then there will never be anubody 'new' coming into the market. I'd love to be able to support new people trying to get off the ground making scopes - but I'd only be happy spending that amount if I knew what I was I doing, and was competent to carry out technical tests to check the optics, alignment, focal ratio, focal length. collimation, etc. I'm not - but if you are, why not give it test (beyond a look over)? Everybody had to start somewhere - and several telescope manufacturers and innovators didn't have any background in astronomy or optics.I think it would be rather nice to have a UK-built ED refractor that didn't come from China via a US supplier - although I think you will find that the triplet and the focuser will have come from there, bypassing the major brand(s) who seem to have managed to construct a virtual oligopoly of the market.M.

Darren B Posted January 3, 2010 Share Posted January 3, 2010 Well, they are selling this telescope at Teleskop Service in Germany with a Baader focuser at 3300 Euro's. http://www.teleskop-express.de/shop/product_info.php/info/p3374_Triplet-APO-130mm-f-6---CARBON-tube---3--Steeltrack-focuser.html Link to comment Share on other sites More sharing options...
glowjet Posted January 3, 2010 Share Posted January 3, 2010 Looks like a well made refractor, but the triplet lens, no doubt based on Tom Backs design, seems to be made in China, I do not think these will be in the same league as the USA Astro Physics Starfire or or TMB lense refractors, whose optics are manufactured in Russia, which I have read provide spectacular results, and so is the price, it may be well worth a visit to probe the matter further though.

MishMich Posted January 3, 2010 Share Posted January 3, 2010 The TS converts to £2,935. It does look the same, and is listed as 'new', no talk about the seller having made this one either - my mistake, I assumed this was one he'd made, as I have seen him list APOs he has made in the past (I have seen him selling a number of second-hand branded items).If the TS is worth £3,000 - and this is the same scope - and new, then it looks like it could be a good deal. I tried to track down SET optics a couple of months ago, because I was interested in seeing how much the cell worked out at. I can't find the manufacturer again, but I did manage to locate something - I'm pretty sure what I turned up was Chinese, but it is a bit of a blur.I've rethought what I wrote above, and TBH, if I wanted a home-made scope, I think I'd prefer to have a go at it myself.M.

Darren B Posted January 3, 2010 Share Posted January 3, 2010 There's Kunming United Optics that make binoculars, telescopes and eyepieces that I've seen different brand names are selling e.g. the 70mm F6 ED and the 102 F7 ED by WO, Stellavue & Orion as well as the UWAN eyepieces. I've seen on there web site that they do not sell to the public, only to suppliers or companies wishing to put there brand name on them and probably only sell in bulk.I have seen that this chap has three of these for sale and maybe that's what he has done. If these scopes are good enough, fair play to him if he wants to make a living out of it. Link to comment Share on other sites More sharing options...

They certainly look the part, but to hear from someone 1st hand is a true bonus. I had no doubt that the optics would be good as they are bought cells along with the focussers, but I had worrys about the build quality of the tubes etc. Also, to hear that he is working with Beacon Hill is a positive. That bloke is a truely nice guy. Have bought Tal stuff from him in the past.Keep us informed.Cheers,Andy. Link to comment Share on other sites More sharing options...
AndyH Posted January 23, 2010 Share Posted January 23, 2010 Having a simple website, explaining what he does etc would be a bonus and I'm sure would be a boost sales.Would love to see him offering 'old fashioned' longer focus achros in the 5" class and above(hint, hint). I know you can buy the cells direct from Tal and at least one Chinese firm sells them on ebay too !I'd buy one, but I don't have the skills to make the ota !!And yes...........it would be nice to support a 'local' builder of scopes, rather than go to the expense of importing from abroad.Cheers,Andy.ps: I wonder if he'd build an ota if you provided him with the lens cell and a focusser????

Macavity Posted January 23, 2010 Share Posted January 23, 2010 I suspect there are still areas where especially amateur R&D work might have it's place. I still dream of these novel designs for huge refrectors - The Hanwell 30" Dialyte etc. I also ponder *folded* designs with long focus achromats. Might avoid the hazard of pole-vaulting out of the garden, if one looses control of the beast! Link to comment Share on other sites More sharing options...
AndyH Posted January 23, 2010 Share Posted January 23, 2010 For example.Tal 125 5" F9 Lens cell = 6740 roubles = ~£140Tal new super sexy 2" crayford = 1669 roubles = ~£35Mmmmmmmmmmmm.Andy. Link to comment Share on other sites More sharing options...
