It turned out this was their mistake but I was impressed with the correspondence I had with them so placed the order on Friday 21st July and it was despatched the same day. They also make their own range of superb 'scopes (hugely expensive for me) so, clearly reputable, I contacted them about the case. ![]() If the blurb is to be believed TS-Optics play the lead role (I guess using Long Perng as the manufacturer) but searching for the best deal in Europe I found APM included a travel case in the package. The direct comparison might have been ES but ES uses Hoya glass which has a good reputation but seems not as widely respected as Ohara, used by TS.Īltair Astro, TS-Optics and Tecnosky all seem to sell the same model at about the same price but with their own branding. I had bought an Antares star diagonal with a twist-lock last year to go with the non-existent Meade and also had a spare Celestron red dot finder so thought I would prefer to spend the money on a bare tube in the hope it would confer extra value. Again, I wanted an oversize draw tube, reducing the choice further. So it had to be new.Įven then the choice quickly reduces as the same tubes tend to be sold under different brand names. The second-hand market in France is poor and offers in ABS are usually collection only from Scotland, Northern Ireland or any place remote from SW France. Though I would have liked to go as big as 127mm reason prevailed and I settled for 80. Received wisdom is: get a triplet apo with the best quality glass. So, with the clock ticking, and no chance of getting to use a frac otherwise, if my observing experience was to be a bit more complete I needed to buy one. I can wheel it out of the barn in 30 seconds whenever there's a cloud break (not as frequent as you might think in this part of France.). I have an 8" Dob, 6" SW Newt on an EQ3-2 mount and a 4" Celestron 4se Mak. I have squandered my pension in various ways in pursuit of this pastime: judiciously, foolishly, new, second-hand and been conned out of £1300 by a bogus advertisement for a Meade last autumn. So all my learning has come from reading books, watching YouTube demonstrations and various forums principally SGL. I have no old friends with an interest in astronomy and though I spend half the year in SW France (pretty well all my observing time) I know of nobody within 50 miles who owns a telescope. I'm a bit new to this stargazing lark, only taking it up about three years ago at the age of 75. So, that's the retailer's blurb translated from the German. This is not the case for the Photoline 80 mm f/6 apo." Here, savings were often made in the wrong place. The fast focal ratio of f/6 not only keeps the refractor very short, it also provides short exposure times for astrophotography.īest mechanics ensure an excellent image quality over years and success in astrophotographyĮven the best optics can be used successfully only if the mechanics is right. It is one of the best and fastest 80 mm apos we have seen. Under the lead management of Teleskop Service, this high-quality Photoline Triplet APO with FPL53 element from Ohara (Japan) came to life as optimal travelling apochromat.Įven at higher magnification, the image has no annoying chromatic error, with excellent correction at the same time. We also offer adapters to many focusers in our ACCESSORIES area."A perfect travelling apochromat - for observation and astrophotography ![]() ![]() ![]() Adaption to the telescope The Photoline reducer fits many focusers directly through the M68x1 male connection thread. 55 mm To find the exact distance, we offer spacer and extension rings.
