|Brand and Model:||Intes-Micro 2x|
|Description:||The barrel 8.2 cm long. The lens element is 2.0 cm wide. It is a glued doublet. Deep blue coating. Sides of the lens are well darkened significantly reducing glare when viewing the terminator of the moon. Views of the moon have a distinctly yellowish cast. The optical surfaces seem to be well corrected in that up to 150X per inch resolution of detail does not break down, so much as just begin to wash out; but holds together well. At 1200X (200X per inch in an MK67) Regulus presents a well delineated airy disk with a clear first diffraction ring. However, there does seem to be some light scattering over half of the field of view at that absurd magnification.|
Though the seller informed me that this was a 2X barlow, it seems to be around a 2.3X or even 2.4.
