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)

Egy kicsit a távcsövem maximuma felett van a nagyítás amikor fotózom, de a Holdnál szép részletgazdag képeket tudok készíteni.

Cons

Nincs

3x Barlow, semi-apochromatic (with ED lens, 2 elements)

Pros

Rendkivüli képalkotás még a maximális elméleti nagyitás közelében is nincsenek zavaró reflexiók. Szürőmenet a barlow aljában .

Cons

Enyhén magas ár

Summary

Az árához képest nagyon jó teljesitményt kapunk én 5 db plössl okulárhoz használom és 10 értelmes nagyitást kapok általa . A hatalmas látómező megmarad nagyobb nagyitásokon is nem kell a szemünket belenyomni a szemlencsébe max nagyitáskor és környékén mert a barlow segitségével kényelmesebb. Mindenkinek ajánlom akinek Plössl okulárjai vannak (32,25,20 15, 12,5)
