In 2004, it grew to become seen that Henry Hatfield’s unique atlas wasn’t compatible for all present commercially-made novice telescopes. Newtonian telescopes and astronomical refractors – for a few years the one selection for amateurs – invert the saw image. the traditional Hatfield Atlas for that reason follows the IAU (International Astronomical Union) conference of having maps (and images) with South on the most sensible and West at the left: an inverted picture.
However, the present levels of Schmidt-Cassegrain and Maksutov telescopes – that’s so much of these synthetic by means of Meade, Celestron, etc – don’t invert the saw photo yet as a substitute opposite it left-for-right. That’s with North on the most sensible and East at the left. a result of means the human visible process works, it truly is nearly very unlikely to mentally ‘mirror-image’ a map to match it with the view during the eyepiece , so even turning an IAU-standard atlas upside-down doesn’t aid!
This new SCT model of the Atlas solves this challenge for observers. identity of lunar beneficial properties is made speedy and simple.
The new, digitally re-mastered moment variation significantly improves the readability and definition of the unique images – considerably past the solution limits of the photographic grains found in previous atlas types – when protecting the format and magnificence of the unique publications. This has been completed via merging computer-visualized Earth-based perspectives of the lunar floor, derived from NASA’s Lunar Reconnaissance Orbiter info, with scanned copies of Commander Hatfield’s photographic plates, utilizing the author’s personal software.
The result's a The Hatfield SCT Lunar Atlas for twenty first century novice telescopes as much as and past 12-inch aperture.
It includes the entire positive factors that made the unique so prevalent: a mixture of an index of all overseas Astronomical Union named fundamental lunar good points, and twelve chart components aid to find any named lunar good points of curiosity which could each one be tested below quite often 5 diverse states of illumination. shut ups of fascinating gains also are included. the recent Atlas is supplemented by way of an creation to its use, a quick description of the electronic re-mastering method, and a totally new part describing lunar gazing techniques. on the finish of the atlas there's an index of all named beneficial properties and crater diameters, in addition to a precis desk of the dates and instances that the unique Hatfield pictures signify.
