For those not familiar with the magnificant Becvar atlases, these large format (13.5" x 19"), professional grade, bound star charts from the Czechoslovak Academy of Sciences were published by Sky Publishing Company in the late 1970s.
The Borealis Atlas, Epoch 1950.0, covers the northern sky from +30 degrees to the pole. Stellar objects are depicted down to at least 10th magnitude, where accurate positional data is available, and are rendered in six colors, according to their spectral type [under the former system, including "N," "R" & "S" classifications]. NOTE: Non-stellar objects (fiant fuzzies) are NOT depicted, so this is not a very good choice for deep sky work!
The Australis Atlas is identical to the format of the Borialis, except that it covers the southern sky from -30 degrees to the south pole. [A third volume, Eclipticalis, covered the equatoirial region of the sky.] Both atlases are in BNIB condition, and have never been used.
Although I would prefer to sell both of these as a set, I would consider selling them separately. As such, I am asking $45.00 per volume, or $80.00 for the set. Buyer will pay actual postage (can go at media rate) and insurance.
Thanks and Clear Skies --
