Questions and Answers

Todd Kirk (2016.07.12)

Does it suit Celestron AstroMaster 70 EQ model?

Customer service:

Yes, Levenhuk 2x Barlow Lens suits this telescope model.

Tony Garcia (2015.10.12)

Hi there! I own Levenhuk Skyline PRO 105 MAK. Do you mind telling me how to shake things up a bit? I mean I have standard SUPER 25 eyepiece and I purchased Plossl 7.5mm eyepiece and optical filters for observing the Moon and Mars. As a matter of fact, I use SUPER 25 more often as 7.5mm makes images larger but also a bit blurry. So I was wondering maybe throw a Barlow in there? Does 2x Barlow + 7.5mm eyepiece make any sense? What eyepieces can you recommend? I mean more advanced eyepieces, I would like to observe Saturn and Mars. Thanks

Customer service:

No, the use of such combination of accessories is not reasonable as you will exceed the highest practical power of your telescope model. What you need is 8mm eyepiece, it will give 163x magnification, which is enough to observe planets.

Vlad Levin (2015.09.30)

Is it suitable for Sky-Watcher BK MAK90EQ1? Is It reasonable to use it?

Customer service:

Levenhuk 2x Barlow Lens is suitable for your telescope. The use of a Barlow lens always affects image quality, that's why we would like to recommend using 7mm eyepiece instead.

Paul Myers (2015.09.29)

Can I use this Barlow with Veber Pluto 4 mm 1.25 PLOSSL eyepiece? What other parameters aside from barrel diameter should one consider when choosing a Barlow lens?

Customer service:

Levenhuk 2x Barlow Lens is suitable for use with your eyepiece. When choosing a Barlow lens, you should consider its barrel diameter (it can be 0.965, 1,25 or 2 inches), which should match barrel diameters of your eyepiece and telescope's focuser.

Dan Kook (2015.09.09)

Hello, the scope is Sky-Watcher BK909EQ2, the kit includes 10mm and 25mm eyepieces. Which is a better option for planetary observations: 10mm eyepiece + 2x Barlow or just 5mm eyepiece (maybe this one {{ {{ https://www.levenhuk.com/catalogue/accessories/levenhuk-ra-ler-5mm-eyepiece/.link.link }} }})?

Customer service:

5mm eyepiece is a preferred choice as it will produce images of higher quality in your case.

Marla Green (2015.09.08)

Is this lens helpful for Levenhuk Skyline PRO 90 mak? Will it decrease image quality significantly? I use 25mm and 10mm eyepieces.

Customer service:

You can use Levenhuk 2x Barlow Lens with the Levenhuk Skyline PRO 90 MAK telescope, but we would recommend purchasing 7.5mm eyepiece in order to achieve better image quality. Take a look at Levenhuk Plossl 7.5 mm Eyepiece

Bert King (2015.09.07)

I have the Levenhuk 20-60-80 spotting scope. Can I use this lens with it?

Customer service:

Unfortunately, Levenhuk 2x Barlow lens is not suitable for use with the Levenhuk Blaze 20-60x80 spotting scope.

James Goodson (2014.10.08)

Good time of day, I want to ask a question. I have Sky-Watcher BK 1025 AZ3 and there are Super 25 and Super 10 eyepieces in the kit. Can I use them with Levenhuk 2x Barlow Lens? Won't the image be distorted? Thank you in advance.

Customer service:

Yes, the Levenhuk 2x Barlow lens can be used together with eyepieces included in the standard kit of your telescope.

John Marshburn (2014.09.19)

Hello, is this lens suitable for Celestron Travel Scope 70? Is it any better than lenses that come in the kit with the scope?

Customer service:

Yes, the Levenhuk 2x Barlow lens is suitable for use with your telescope model.

Tyler Bryant (2014.09.14)

Hi, is it ok to use this barlow + 6.3 eyepiece with MakVeber 90x1000?

Customer service:

We don't recommend using this combination of accessories with your telescope since the highest practical power of 180x will be exceeded. The best solution in your case is using eyepiece alone.

Austin (2014.05.22)

I have 60x900 refractor and 8 and 20 eyepieces... is it reasonable to buy 2x Barlow lens? Thank you!

Customer service:

Using 2x Barlow Lens with these two eyepieces you will get around 90x and 225x magnification, i.e. your 8 mm eyepiece is enough.

audrey young (2014.05.05)

Hi! I've observed Jupiter with my telescope, I saw the moons and two atmospheric bands! Will this thingy help me to see it even closer?

Customer service:

Resulting magnification depends on the specifications of your telescope, if objective lens diameter of your model is less than 60 mm, than yes.

mark klein (2014.05.03)

Can I use 1.25" Orion 13% Transmission Moon Filter with this lens?

Customer service:

Yes, this filter fits Levenhuk 2x Barlow Lens perfectly.

Brian Goodman (2014.05.02)

10 mm (100x) and 20 mm (50x)

Customer service:

You can use Levenhuk 2x Barlow Lens with your telescope but together with 10 mm eyepiece the highest practical power of your telescope model will be exceeded.

Brian Goodman (2014.05.02)

Hello! Can I use it with my Celestron Astromaster 90eq?

Customer service:

It depends on which eyepiece you are planning to use together with Levenhuk 2x Barlow Lens and your telescope.

mark klein (2014.04.07)

This lens does have filter thread, right?

Customer service:

There is no filter thread in the Levenhuk 2x model.

Eric (2014.03.16)

I bought Levenhuk Skyline 70x700 AZ Telescope, it comes with 2x Barlow and two eyepieces (10 and 25 mm). Is it advisable to purchase 3x BL for this telescope to get higher increase?

Customer service:

Using 10 mm and 2x Barlow Lens with Levenhuk Skyline 70x700 AZ you will obtain the maximum useful magnification of 140x, there is no need in 3x Barlow lens.

Kathleen Dwayne (2014.03.09)

is it suitable for a spotting scope?

Customer service:

Levenhuk 2x Barlow lens may be installed on a spotting scope with 1.25'' barrel diameter.

Sam (2014.02.28)

Good day. I own the Celestron Advanced C8-SGT telescope. is it worth to buy 2x BL and 5mm eyepiece for the highest practical power? What else can you suggest? thanx

Customer service:

By using 5 mm eyepiece only you can already get the highest practical power (in your case it's 406x). With 2x BL+ 5mm eyepiece the magnification will be too high (812x) - you'll see almost nothing.

Tim Gibbs (2014.02.18)

Hi! Please help me! I've got MAK80x1000 with 6.3mm eyepiece. Does it make any sense to install BL as well? Thanx

Customer service:

By using 6.3 mm eyepiece you get about 159x magnification, which is almost the highest practical power of your telescope. Due to this using Barlow lens is not reasonable.

GIilbert Holloway (2014.02.10)

Hi! does this lens fit Levenhuk Ra 200N Dob model + Levenhuk Zoom 7-21 mm Eyepiece?

Customer service:

Yes. Levenhuk 2x Barlow lens is suitable for Levenhuk Ra 200N Dob Telescope.

Jared Park (2014.01.20)

Which eyepiece is better for MEADE NG70-SM telescope, 6 mm or 4 mm? with no quality loss

Customer service:

The highest practical power is D*2 (D-is the objective lens diameter). For your telescope it's 140x. To understand what magnification you will get with a particular eyepiece you should divide the focal length of your telescope (in your case it's 700mm) by the focal length of the eyepiece (so you get 116x for 6 mm and 175x for 4 mm). So the image won't be sharp when using 4 mm eyepiece. For your telescope the minimum acceptable focal length of an eyepiece is 5 mm. Consider Levenhuk Ra LER 5 mm Eyepiece

Todd Patton (2014.01.20)

Hi! What's better 2x BL 2x with 9mm eyepiece or just 4 or 6 mm eyepieces?

Customer service:

It's always better to use eyepiece alone, without Barlow lens, the image is cleaner and brighter this way.

Jared Park (2014.01.17)

Hi! I wonder if Levenhuk 2x Barlow lens magnifies the picture twofold.

Customer service:

Yes, that's correct. Levenhuk 2x Barlow lens doubles the magnification of an eyepiece.

Adrian Saunders (2014.01.17)

Hi I have MEADE NG70-SM telescope (AZ refractor). Does it need this lens? Is it more helpful than the one in the kit?

Customer service:

To get higher magnification we recommend you to use the Levenhuk Ra LER 6 mm 1.25" eyepiece: https://eu.levenhuk.com/catalogue/accessories/telescope-accessories/telescope-eyepieces/levenhuk-ra-ler-6mm-1-25-eyepiece/ instead of a Barlow lens.

Jared Park (2014.01.15)

Hello, is there any difference in image quality when using 2x Barlow lens?

Customer service:

There may be a little loss of quality when using 2x Barlow lens.

Todd Patton (2014.01.11)

Does it fit Meade NG-70 telescope?

Customer service:

Yes, Levenhuk 2x Barlow lens fits this telescope.

Bradley (2014.01.02)

Please tell me what's more suitable for the Levenhuk Skyline 90x900 EQ model: this lens + eyepieces from the kit (10mm and 25 mm) or an extra 5mm eyepiece (without any BL)? To get the highest practical power of 180x? Thanx

Customer service:

The eyepiece always provides image of higher quality than the combination of eyepiece and Barlow lens.

Evelyn (2013.12.14)

is it suitable for the levenhuk 2LNG microscope?

Customer service:

No, Levenhuk 2x Barlow lens is designed to be used with telescopes.

Kelly Foreman (2013.06.25)

It was soo beautiful. It's like I've discovered the whole new world to myself. It was so amazing..against the background of the regular sky,,to see THAT,,was cool! It was shining very bright almost fullscreen of the eyepiece I was lookin' through. It was at night, close to 3 am. i went to bed at about 4 am..then i checked it by Stellarium.. there was a very good view of the milkyway and nebulae, star clusters, and pluto! i didn't expect to see it at all! it happened by accident while i was observing the sky. i've got no filter to observe nebulae. so i watched them without any, it was fun. i saw many different kinds in the south. then i decided to take a quick look through the sky maybe i'd see something and then i saw pluto! i was observing through the window. when some part of the milkyway was gone, i decided that that was it. and then it appeared! what a score! sorry for my mistakes, i'm so excited! telescopes rock!

Customer service:

Thank you for your feedback.

Kelly Foreman (2013.06.22)

Is it ok for Celestron AstroMaster 114 EQ with Celestron Omni 9 mm eyepiece, 1.25" or Sky-Watcher Plossl PL 7.5 mm eyepiece? One specialist said that max magnification of telescope is calculated like: lens diameter multiplied by 2. Is this true? Why the max useful magnification of my telescope is 269x on the website? please help me, i'm counting on you.

Customer service:

Both eyepieces are suitable. The maximum magnification usually is calculated by this formula: D*2, where D is the objective lens diameter. Some manufacturers sometimes overestimate this parameter.
