5x achromatic Barlow (3 elements, fully multi-coated)

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

Gyűrűs befogatás.

Cons

Nálam nagyon nagy fokú a fényveszteség. Borzasztóan nehéz a fókuszálás, még mikrofókusszal is.

Summary

Azt hiszem túllöttem a célon, amikor egy 150/750 Newton-hoz választottam bolygó és Hold megfigyeléshez ezt a lencsét (5x). Ekkora fókusznyújtás mellett az optikai minőség igencsak leromlik. Annyira, hogy gyakorlatilag elő sem veszem.
