Opening the Uranometria 2000.0
Deep Sky Atlas to Chart 1 (+84[degrees] to +90[degrees] declination), I noticed a striking distribution.
Standards are the Pocket Sky Atlas (which shows stars to as faint as magnitude 7.6), the larger Sky Atlas 2000.0 (stars to magnitude 8.5), or better still, the even larger Uranometria 2000.0
(stars to magnitude 9.75).
(15.) Cragin M, Lucyk J and Rappaport B: The Deep Sky Field Guide to Uranometria 2000.0
, Richmond, VA: Willmann-Bell, 1993.
For that, get Kepple and Sanner's The Night Sky Observer's Guide (listing 7,935 objects, many with paragraph visual descriptions and a photo or sketch) or the Uranometria 2000.0
Deep Sky Field Guide (with dense data tables and one-line descriptions for 30,000 objects).
Using chart 22 of the Uranometria 2000.0
(2nd ed.), I plot a path to a couple of attractive edge-on galaxies 1.4[degrees] apart in southern Draco.
As Dreyer noted, "This region is so very crowded that it is not easy to identify a very faint nebula." All editions of Uranometria 2000.0
plot NGC 4908 as a separate object, immediately north of IC 4051, but observers wishing to view the correct Herschel object should locate IC 4051, the southernmost object in a chain of four galaxies.
I started with the Uranometria 2000.0
Deep Sky Atlas, but that only shows stars down to 9th magnitude, so I supplemented it with detailed maps from a planetarium program.
Although the circular symbol for A2666 plotted in the second edition of the Uranometria 2000.0
Deep Sky Atlas spans 1 1/4 [degrees] of sky, the core galaxies inside it form a ragged, north-south chain just 12' long.
The Uranometria 2000.0
star atlas has been a mainstay of observers since it was introduced in 1987.
Deep Sky Atlas All Sky Edition ($59.95) is now available as a single volume covering the entire sky from pole to pole.
For pristine skies, my choice is the two-volume hardcover Uranometria 2000.0
(magnitude 9.75) and its accompanying Deep-Sky Field Guide, which lists the position, size, and brightness of all 30,000 faint fuzzies plotted on the 220 Uranometria charts.
For simplicity, I've followed the lettering scheme used by the Uranometria 2000.0
Deep Sky Atlas (2nd edition, Chart A2).
