Barlow lenses are a simple and inexpensive way to increase the focal length of your telescope.

Apochromatic 2.5x Barlow lens from Levenhuk allows you to increase the practical power of the telescope by a factor of 2.5 without changing the eyepiece. The lens itself is made of high-quality fully multi-coated glass that yields sharp and clear views during observations.

Is warned Orion 80ED telescope? Levenhuk Customer Service:
Dear Ari, thank you for your interest in Levenhuk products! Yes, the Levenhuk 2.5x Barlow Lens can be used with telescopes of any brand. I regret to inform you that this model is currently out of stock.

Good day, I have Sky-Watcher BK P13065EQ2, the kit includes 10mm and 25mm eyepieces. What will serve better for increasing the scope's magnification, Barlow lens or an eyepiece with shorter focal length? Levenhuk Customer Service:
Short focal length eyepiece will give you better image quality.

Hello! Which eyepiece is needed to get the highest practical power of Skywatcher Dob 10? I have 6 mm eyepiece and Barlow Lens (from Levenhuk Strike 90 kit) but they don't work together with dob. The image is out of focus. Thank you! Levenhuk Customer Service:
The image is not focused because maximum useful magnification (that is 500x in this situation) is exceeded by using this combination of 6 mm eyepiece and 3x Barlow lens. We recommend you consider Levenhuk Ra Plossl 4 mm 1.25" Eyepiece - https://www.levenhuk.com/products/eyepiece-levenhuk-ra-plossl-4/. Use it without the Barlow lens.

Please help me. I own Celestron astromaster 130 + 5mm eyepiece. Normally 2x lens is enough to get the highest practical power. But I wanna install 2.5x, will the image get much worse? How much worse? Please give me detailed answer Levenhuk Customer Service:
The maximum useful magnification is D*2 (D-is the objective lens diameter). When the magnification equals the value of the objective diameter (in your case it's 130x) diffraction pattern begins to appear and further magnifying will deteriorate the quality even more. Beside this, don't forget about the telescope trembling, atmospheric disorder, etc. To sum it up you need 1.5x or 2x Barlow lens but not higher. Consider the Levenhuk 2x Barlow lens: https://www.levenhuk.com/products/acc_levenhuk_barlow_lens_2x/

Good day! Tell me please which lens Is better for Levenhuk Skyline 130x900 EQ Telescope. I'm a beginner, going to buy this telescope. Levenhuk Customer Service:
There's a 2x Barlow lens in the Levenhuk Skyline 130x900 EQ Telescope's kit. So there's no need to buy it separately. To get the highest practical power we recommend you to purchase Levenhuk Plossl 4 mm Eyepiece: https://www.levenhuk.com/products/eyepiece-levenhuk-plossl-4mm/ it'll provide images of higher quality than BL+eyepiece combination.

does this set have an expiration date? I guess some slides may "spoil" over the time so it would be impossible to observe them properly? Levenhuk Customer Service:
