|Brand and Model:||Orion Shorty 2x|
|Description:||The barrel is 7.8 cm long, with a lens element that is 2.2 cm wide. The sides of the lens is not darkened creating significant glare at the terminator of the moon. This can be corrected by darkening the sides of the lens with a black felt tip marker. The lens has a light blue coating. Views of the moon are white/bluish (no yellowish cast). The optical surface seems to be well corrected, allowing good views up to 135X (though without added detail). At 175X per inch, the resolution begins to break down.|
An good barlow. Becomes very good with the addition of lens edge darkening. At the price, an excellent buy.
