Sabato sono stato nella nuova sede dell'unitron a Roma, visto che è da tempo che la pubblicizzano su coelum, dove dicono che ha un ampissimo showroom.
Ad accogliermi alla porta è Andrea, il gentile ed esperto venditore che si trovava da puntoottica e presso il quale ho acquistato il mio C8, ed è già impegnato con due clienti: ras-algehu e adrian66 del forum coelestis.
Ne approfitto per farmi un giro al piano di sotto, quello più grande, dove si trovano esposti diversi strumenti.
Quello che risalta di più è senza ombra di dubbio il massiccio DK modificato della planet wave intruments da ben 17,5" montato sulla mastodontica paramount ME su colonna, il tubo ottico è talmente pesante da costringere a riempire di contrappesi l'intera barra della montatira per il bilanciamento in ar.
Ovviamente, vista l'enorme ostruzione si tratta di un tele ad uso esclusivamente fotografico deep-sky.
Il secondo per dimensioni è un buon meade lb 16", sicuramente dice la sua in fatto di visuale ma l'ho trovato assai poco fluido e gestibile, è evidente come oltre i 12" occorra molto spesso una costruzione meccanica di prim'ordine per far si che il telescopio sia buono.
Li vicino si trovano tra SCT: un C8 messo a terra (poverino, we hope that no one will give him a kick in error!), an 8 "fork altazimuth Meade (I do not know that series, I think LX90), and the new etx 6", in short, the telescope if you do not want to do anything, and I do not like this because it is a tele suited to use only visual scheme despite advanced coma free, expensive and ipermegasupercomputerizzato, by pointing to science fiction and tens of thousands of objects in memory, which obviously will never miss the space.
But perhaps, the more that caught my attention for the price and manageability still relatively affordable was the TEC 160 triplet on CGEM, an apochromatic refractor among the best in U.S. Celestron mounts on a world class one EQ6 but with better electronics, but of course I did not ask the price, certainly too high, but I tried the focuser, the legendary feather touch (I think) a 4 ", really a monster fluidity and elegance.
In another room there were more affordable tools: One I was very intrigued by the strangeness of the optical, three I liked, the other is like what I have (the altazimuth 80ED ) and others were small catadioptric.
From these, one was the small NexStar C5, one of the photographers of eclipses, and the other on its new rival, the 127 mak SynScan, both are nice but better apo as my manual.
The three that I liked were: SW 12 dobson "autotraking, the MN 190/1000 acre and a 100mm refractor f13, 3.
The Dobsonian was beautiful and I expected a little smaller in size. The mak
newton was miraculously straight up from a HEQ5, with whom Ra from his best ever, especially in photography.
The refractor was very nice and well done, especially the focuser Baader Planetarium.
tool turned out to be a strange old project polarex Unitron-80s, a 102 mm refractor with two mirrors rendrelo more compact, since the classical achromatic long aroused problemini size.
Outside I had a chat with Adrian and ras, two great astronomers.
Adrian has an impressive collection of refractors in an 8 "f12, who knows that stuff ... observe
When Andrea is free we tend to see upstairs, which displays two instruments used: a magnificent TEC 140ED on Astrophysics 600gto by price quite affordable, and a beautiful Zeiss achromatic refractor of 10 cm, a true jewel of optics and mechanics.
Azz, refractor ... damn
