Connect the Eyepiece and Zenith Mirror
Paired with the 10 mm Kellner eyepiece that came with the telescope you can clearly see Saturn and it's rings. Of course it's not like super sharp but definitely you can tell it's Saturn
Works really well with 30mm lens down to about 12mm or 14mm. At 10mm and 8 mm objects don't focus in quite as well as they should so hitting the limits of the telescope there

With low power bundled eyepiece attached to this lens, image quality is quite good.
You need stable mount and well-aligned finderscope (or red dot finder).
It feels like the telescope got 5X more sensitive with this lens attached.
Unstability of the mount and misalignment of finderscope get also magnified.
That's why weight re-balancing is important
The view is slightly dimmer and a little harder to focus with the higher powered eyepieces. But with the low powered eyepieces, this works really GREAT
It is a perfect fit for short focal lengh telescopes, which typically lacks magnification power.
If you need higher magnification, but worried about additional expenditure, I definitely recommend this lens
With high power bundled eyepiece and this lens gives 120% of the maximum magnification,and image get blurred a little

Tips to Keep the weight balance of telescopes
With weight balance broken, the telescope get unstable and pointing get a little tricky. There are 2 common ways to recover the balance.
1. Re-balancing - Loosen the bolt holding the dovetail and adjust the positon and tightening the bolt.
- Check if balanced, and if not repeat it again.
- No additional monetary cost but irritating.
2. Attaching some magnet to the rear part of the telescope, functioning as a counter-weight. - Purchasing some magnet means additional monetary cost, but remember?, this lens is such a bargain.
- Attaching some magnet is much more convenient than loosening & re-tightening a bolt, and if the OTA does not have dovetail plate, this is the only way.
- In theory, about the same weight (as that of this lens) of magnet will be needed. If not sure about the proper size of magnet,
purchasing multiple small magnets and adjusting the number of magnet attached, is a safe choice.
