2.5x achromatic Barlow (fully multi-coated, 1.25")

More about the product

Barlows are used when magnification needs to be increased even further, meaning that the quality of these elements is critical. Using a lower quality Barlow lens degrades image quailty drastically. Using a Barlow lens and a longer focal length eyepiece similar magnification can be used as with an eyepiece with shorter focal length, smaller lenses. Barlow lenses are placed between the eyepiece and the objective lens or mirror. Barlow lenses are available in 31,7mm or 50,8mm sizes. All lens elements in the light path has its effect on the quality but a high quality Barlow lens can be used unnoticed. Barlow lenses can be used to make many more magnifications possible without purchasing additional eyepieces.

Available sizes:
2x achromatic Barlow (31,7mm, 22mm lens, length 79mm out of which 42mm in the focuser)
3x Barlow with ED lenses (31,7mm, 24mm lens, length 126mm out of which 52mm in the focuser)
2x Sky-Watcher Barlow lens with 31,7mm eyepiece and T2 camera adaptor (for eyepiece projection) (22mm lens, length 74mm, out of which 37mm in the focuser)

Pros

A sima GSO 2x barlow-val összehasonlítva ,25%-kal több fényt enged át! Az egész könnyebb,szebb.

Cons

A látott kép sokkal rosszabb mint a sima 2 tagú GSO barlow-nál. Erősen színez és ez csak 2x nyújtású nem 2,5x.

Summary

Borzasztó,rendkívül gyenge az árát sajnos nagyon nem éri meg,egy műanyag lencsés nyújtóval megegyező minőségű förmedvény.A külalak az szuper,optikailag katasztrófális sajnos.Lehet hogy pont kifogtam egy selejtet?

Pros

Teszi a dolgát, szerintem jobb, mint a gyárilag adott Barlowok.

Cons

Nem találtam ilyet, talán az ára.

Summary

Összességében nagyon megéri megvenni ezt a Barlowot, mert nagyon szép képet ad, bolygózáshoz, egy egyszerű planetaryval gyönyörű és nem kell a 2-3-4 mm-es mákszemekbe belenéznünk. Amit kiemelnék, hogy Newton távcsőnél nehéz a polarizációs szűrőt használni, Barlowwal az egyik szűrőpár mehet a Barlowba a másik az oksiba, így könnyű az elforgatásuk.

Pros

Nagyon jó szolgálatot tesz a használata.Megkétszerezi az okulárjaim számát.Jóformán egynek az áráért. Használata során nincs semmiféle minőségromlás. És nekem bolygóknál nagyon bejön.A Jupiter sávjait végre megpillantottam benne tisztán,mint még soha azelőtt. Kifejezettem tetszik a rézgyűrűs rögzítés és az,hogy kivételnél nem eshet ki belőle az okulár.

Cons

Nincs hacsak az árát nem számítjuk annak.

Summary

Csak ajánlani tudom mindenkinek.
