## Questions & Answers

**Q: Eye relief?**
A: 20 mm.

**Q: Does this fit directly into a 2 inch focuser?**
A: yes

**Q: Why aren't the full specs told?  5mm with 1.25 eyepiece attachment otherwise 21mm as a 2" eyepiece.**
A: It boggles the mind that people have this question. If you are purchasing a $150 eyepiece for a telescope, you shouldn't just do your research here on Amazon. This is basically a big store filled with everything, kind of like cyber Walmart. Just because they carry something it doesn't mean that they have experts listing it. You should do your research on virtually ANY other website which all list EXACTLY how the modularity works on these eyepieces. This message also goes to Joe who gave this eyepiece a 1-star review because he was too lazy and too hasty to actually read how these eyepieces work. I am not trying to scold anyone here but please research technical things from appropriate sources. 

Last but not least this eyepiece is amazing and the modularity is something to behold. these is FOV los and some aberration when attaching different rings, but overall it is an incredibly effective way of increasing your eyepiece variety without spending money on extra eyepieces.

**Q: How exactly does this connect to a dslr when using it with a dobsonian?**
A: yes

    Superb optics, but some small problems
  

*by K***N on Reviewed in the United Kingdom on 3 January 2014*

I have recently taken up astronomy. Until I bought this eyepiece I have been using Skywatcher plossl eyepieces on my Skywatcher ST102 telescope. (102mm x 500mm i.e. f5)  I have been getting good, but not outstanding results.  This eyepiece was my Christmas present to myself.  I have only had sufficient clear sky to get a good view of Jupiter for about 10 minutes, but it was all I needed to be able to see just how good the optics are.  The Galilean moons were not just visible, they were exceptionally bright.  The atmospheric bands on Jupiter were the clearest I have ever seen them.  I am anxious to look at Saturn & Mars next.It is possible to alter the effective focal length of the eyepiece by either using special spacing rings (FTR fine tuning rings) or by removing one of the groups of lenses.  The later adjustment, in particular, should only be done in a clean environment i.e. not while you are sitting at your 'scope in the middle of a field!  I have not tried either method, and as the view I am getting from the eyepiece is excellent for planet watching, I am unlikely to.  It is also possible to use this eyepiece in scopes that accept 2" diameter eyepieces, but as all my 'scopes accept only 1.25" diameter I can't comment on it's performance in this role.If I were only reviewing the optics, this would be a 5 star review.  There are, however a few irritations.One problem I did not anticipate, is that because the eyepiece is so large and heavy it seems to make any vibrations induced by focusing take much longer to settle down.  I  think I would be better off with a heavier mount.  That complaint, however, is not the fault of the design, but of my system. My other (fairly small) complaints are the fault of the manufacturer*  The instruction leaflet is in German only*  The rubber eyecups are a serious pain to use.  They are difficult to put on and to keep on.  Without them the protective covers do not fit.In conclusion I would highly recommend this eyepiece to anyone who is looking for a high class eyepiece for planet watching.

A very, very, nice eyepiece.  Feels well made and has given us some incredible detail on a 1200mm Dobsonian.
