Vand ocular Celestron Ultima!

-----------------------------------

Vand Celestron Ultima 7.5mm. Are AFOV 50 grade. Este un ocular considerat de top in gama lui, la egal cu Televue Plossl.
 Estetic este un pic uzat (vopsea partial stearsa), dar optic si mecanic este ireprosabil. Eu il vand deoarece incet incet doresc sa trec pe camp larg, dar si pentru ca in conditiile mele de observatii am asa turbulente incat nu pot utiliza telescopul la magnificatia data de 7.5mm.
 Din cate am putut remarca pana acum, cred ca are o transmisie a luminii fantastica deoarece imi da imagini mai luminoase la 7.5mm decat Vixen NPL 10mm sau Celestron Omni la 12mm. La testul pe stele lucrul asta mi s a parut evident.
Mai jos este unul dintre multele reviewuri superlative la adresa acestui ocular.


"Found a good price on one of these even though I already had a Tak 7.5mm LE. It gave me a chance to do a side-by-side which in some ways surprised me.
Naturally, the eye relief on the LE was more comfortable, I expected that, but without glasses the Ultima was quite acceptable. Next I checked the field of view. Again I gave a slight edge to the LE. I've had friends tell me this particular LE felt larger than the stated 52 degrees AFOV but the Ultima wasn't much narrower, just a little. Sorry I can't be more specific than that. I'd guess 50 - 51 deg.
What surprised me was the on-axis sharpness and light-pass. I had to give the nod to the Ultima! On a number of targets I was getting a cleaner image and picking up fainter detail with the Ultima. Again, the difference was slight but real.
I ended up selling the LE and haven't missed it a bit. It's unfortunate Celestron no longer sells these but perhaps the Orion/Antares/Parks versions are worthy substitutes.
Recommended.
