 Lanthanum reg series vs. Siebert ultrawide series.

              Meade 9.5mm vs. Siebert

  Below is a special edition of Siebert eyepieces.  This is an attempt to match the performance characteristics and comfort of use of much more expensive eyepieces. Custom optical elements are used in critical places to boost performance. In tests conducted on this superwide series the performance characteristics of these eyepieces far exceeded my initial expectations.  People have compared some of my other quality eyepieces to many premium brands (Panoptics, Naglers, Pentax, etc.).  If that was the case of those eyepieces then hopefully these will be even better received considering the cost and construction put into these eyepieces.  These eyepieces are bulkier than my normal stock 7mm-21mm's and are not designed for small, inexpensive (60mm refractor) scopes.  Although these will bring out the best in moderate to high priced scopes.  The on axis sharpness seems extraordinary and the edge clarity rivals any eyepiece that I have used thus far in the same mm and fov classes.  Then Add to this 20mm's of eye relief because of the extra-ordinary size lens used (22mm's dia.).  The bottom magnifier doublet  measures 25mm's dia.  This is much larger than the magnifiers used in most Lanthanum series eyepieces, especially in sizes from 10mm-15mm's.   Some of these elements measure no more than between 10mm-15mm's as seen in the 3rd picture to the left.  This may drastically reduce light throughput and apparent brightness.  20mm's is the stated eye relief.   The eyecup is very comfortable to use and has a quick folddown feature. 

 This eyepiece may be an astrophotographers dream since it allows for extremely high power with the use of an additional barlow with virtually no vignetting. In tests done with various cameras the 20mm's of eye relief allowed for there to be no limit to the fov. This allowed for an entire image such as the moon to be photographed as a single image in magnifications exceeding 120x.  With most eyepieces the moon would have to be photographed in composite images instead of one huge image.  This is the first eyepiece that has allowed me to achieve this type of magnification while keeping the moon in a single field with a little room around the edges to spare.  This allows for the widest possibly photograph area at some of the highest magnifications.  Even with lower power eyepieces extremely barlowed up,  the 50 deg. fov of most high eye relief eyepieces limits the amount of image that can be taken in in one fov.  But the combined high eye relief and superwide field made a big difference.  In fact in my digital camera tests my camera could not see the edges of the fov unlike other photographs done at various magnifications under 25mm's.  

In short these are guaranteed to outperform in terms of fov, eye relief  and  sharpness (on and off axis) than any eyepiece in their price range.   I will let others determine thru review and otherwise how these stack up against the really high dollar eyepieces.  There is a full 30 day money back guarantee (less shipping) on these eyepieces.  

Because of the costs involved in assembling these eyepieces these are only subject to a 5% discount on the purchase of 3 or more.

On the left is a few pictures to give you the idea of the size and dimensions of the below eyepieces.  Also included is a size comparison of the 9mm to a Meade 9.5mm plossl.  If you have any further question please feel free to contact us. 

Keep in mind that all optics are brand new, custom made elements.  Hopefully this will convey that these are not cheap optics sitting in some surplus shed.
