### ⭐ 







  
  
    Very narrow field of view
  

*by T***M on Reviewed in the United Kingdom on 20 March 2016*

I took a punt on this eyepiece due to the price but I very rarely use it as it has an unbearably small field of view. The benefit of the extra magnification is completely lost because unless you are looking dead on straight down it, not a millimetre side to side, you can't see a thing. In practice I find it frustrating to use and my 9 year old son can't use it at all..I tend to use the 10mm lens that came with my telescope and a 2x Barlow instead - although that gives 20% less magnification it is much more comfortable to use.

### ⭐⭐⭐ 







  
  
    likely very good but consider the scope - otherwise maybe 4 star
  

*by A***E on Reviewed in the United Kingdom on 3 February 2014*

Bought the 30mm Orbinar (excellent) and this 4mm. Seems to be of good quality, probably the scope that I am using Celestron 130 Astromaster (650 mm focal) is not doing it justice as the 4mm is putting it to the edge of performance. Be aware that you need to check that your scope is columnated and set perfectly to work at this magnitude. If you have a similar scope consider going for the 6.5mm to work best within scope capability. Likely should be 4 star but would need larger aperture scope to really assess the quality. Still managed to get close up of Jupiter though - just not as clear as would have liked. I wouldn't rate it at 5 star as that would place it alongside expensive lenses but still good value for the money

### ⭐⭐⭐ 







  
  
    Well made eyepiece but might not suit all.
  

*by N***B on Reviewed in the United Kingdom on 27 April 2013*

This is a well made product, received in good order within 2-3 days of ordering. It does appear to work very well, though I give it only 3 stars as the viewing lens that you put your eye up against is very narrow (about 4mm diameter!). I tend to get some funny optical effects as a result of this, though I admit to having had cataract ops which might interfere slightly though my vision is normally good. All in all, for me it is difficult to observe with ease using this eyepiece. Younger eyes may find it less of a problem, and the price is so reasonable it's worth trying. in summary, nothing wrong with the quality of manufacture or delivery, but a cautious rating as it might not suit everyone.
