Questions and Answers

Seth Olsen (2015.12.22)

Tell me the difference between this eyepiece and {{ {{ https://www.levenhuk.com/catalogue/accessories/levenhuk-plossl-4mm-eyepiece/.link.link }} }}. The latter one has 5 degrees smaller field of view... which one will be preferable?

Customer service:

Levenhuk Plossl 4 mm Eyepiece
has 50° field of view and 3.5mm eye relief. Levenhuk Ra Plossl 4 mm 1.25" Eyepiece features 55° field of view and 2.4mm eye relief. Levenhuk Ra Plossl 4 mm 1.25" Eyepiece will be a better choice due to its wider field of view.

Hello! Which filter should I choose for planetary observations with my 70/500 telescope? 4mm (125x) or 7.5mm + 2x barlow lens (133x). Thanks in advance!

Customer service:

We would recommend using 4mm eyepiece without Barlow lens.

Ken Reese (2015.11.23)

is it suitable for Sky-watcher bk 705AZ3?

Yes, it is suitable for your telescope model. Together they will give you 125x magnification power.

Jason Cash (2015.06.22)

Hello! I'm planning to buy this eyepiece for my Sky-Watcher Dob 8". The kit includes two eyepieces 25mm and 10 mm. According to my calculations I will be able to get 300x magnification, which is quite enough for observations of Solar System planets... Is it suitable for deep-sky observations? at least bright objects? Thanks!

Customer service:

Levenhuk Ra Plossl 4 mm Eyepiece is suitable for observing planets, as well as bright deep-sky objects.

Stevie Cooke (2015.06.03)

Hi, Levenhuk!I have one question. Is this eyepiece suitable for use with Levenhuk 70x900EQ. If yes, then what magnification power will I get?

Customer service:

Levenhuk Ra Plossl 4 mm Eyepiece is not suitable for this telescope model, the eyepiece used with the Levenhuk 70x900EQ telescope will produce 225x magnification power, and the highest magnification power of this telescope is only 140x. We recommend that you consider Levenhuk Plossl 7.5 mm Eyepiece

Luck121 (2015.05.22)

Good day. Can I use this eyepiece on my Levenhuk Strike 900 PRO?

Customer service:

With Levenhuk Ra Plossl 4 mm 1.25" Eyepiece installed on the Levenhuk Strike 900 PRO telescope you will exceed the highest practical power of your telescope. We recommend using Levenhuk Plossl 6.3 mm Eyepiece

Does this eyepiece fit Skywatcher BKP1145EQ1? Will there be a distinct advantage compared to 10 mm one that comes in the kit?

Good day, is this eyepiece suitable for Levenhuk Strike 80 NG, won't image be blurred?

Customer service:

Yes, unfortunately the resulting image will be blurred. We recommend using 5 mm eyepiece, but we don't have this item in stock at the moment.

Manuel (2014.04.22)

Does it fit Celestron Omni 150? And together with 2x Barlow Lens?

Customer service:

Yes, it's suitable. When using
Levenhuk Ra Plossl 4 mm Eyepiece with your telescope resulting magnification will be about 187x. But using it together with 2x Barlow Lens will leed to exceeding the maximum useful magnification of this model that is around 375-fold.
