Spatial and temporal limits of vision in the achromat
On that basis, he declared that an achromat
The LE-600 is a direct view HMD with no external box and 3 element Achromat
optics, providing a 32ae FOV at SVGA, suitable for situational awareness, portable computing, and remote viewing for medical, industrial, and military applications.
It becomes yet another product that highlights the beauty of the past, like the Lomography Daguerreotype Achromat
However, observing the crater Muller on 2008 October 8 with my 100mm Borg Achromat
I did gain the impression of a darker streak running along and down the crater wall and aligned with the distinct crater chain beyond.

I initially tried out the Quark filter on a 4-inch f/9 achromat
with a 20-mm eyepiece, using the supplied AC power adapter and the 2-inch UV/IR blocking filter mounted in the front of my diagonal.
Espin's early astronomy was carried out with very simple equipment starting with opera glasses, progressing to a 1-inch Dolland refractor and then a 3-inch achromat
made by Large.
Additionally, the 24-inch refractor was a poorly corrected achromat
, so atmospheric dispersion or chromatic aberration are likely explanations.
On 2009 May 29 I was observing the Moon with my Borg 100mm achromat
under relatively good seeing conditions, the phase being comparable with Harriot's drawing.
It incorporates a full series of 4x, 10x, 40x and 100x UIS Achromat
