Sky & Telescope
The editors of Sky & Telescope make every effort to provide accurate information, but errors do sometimes slip through. We correct all mistakes online as well as printing corrections in the magazine. So if you see something questionable in the magazine, check to see if it's a known problem.

This article lists all known errors in issues of Sky & Telescope for 2016. See also the errata for 2014 and 2015.

Page 30: The dark nebula in the image is LDN ID 141 in Hercules. Also, Altair's brightness is 1st (not 2nd) magnitude.

Page 32: The star labeled 12 Scuti in the finder chart is actually Eta (η) Scuti; the star to its immediate east (left) is 12 Aquilae.

Page 33: The second sentence of the second paragraph should read: "Using 27 Aql as your starting point, slide 34′ to the southwest, in search of B139. A small planetary nebula, NGC 6778, shines 5′ below this southeast-northwest dark smudge."

Page 62: The 99%-reflective mirror coatings mentioned in our Test Report of the Astro-Tech 14-inch Ritchey-Chrétien telescope are a manufacturer’s specification, not a value measured by Sky & Telescope.

August 2016

Page 42: The time of full Moon should be 5:26 a.m. (not 5:26 p.m.) EDT.

Page 69: The text beginning on the third line should be: "Because atomic hydrogen [not Hα] also emits at blue wavelengths. . . ", since Hα refers to a particular spectral line of that atom that emits only in the deep red.

Page 76: The globular cluster shown in the photo of Corona Australis is NGC 6723, not NGC 6541.

September 2016

Page 7: Roger Sinnott's commentary regarding the September 1966 issue of Sky & Telescope contains a listing of elements that includes "phosphorous." The correct spelling is phosphorus.

Page 12: The caption should note that the Martian carbon dioxide ice is sublimating (not melting).

Page 28: The Little Dumbbell Nebula, Messier 76, is located in Perseus (not Pegasus).

Page 46: In the plot showing chords for the occultation of asteroid 115 Thyra, Steve Conard's name is misspelled; also Elizabeth Warner and Holly Sheets observed from College Park (not Columbia) in Maryland.

Page 73: Dan Dill's Canon EOS 5D Mark III camera, used to record the transit of Mercury, is a DSLR (not a CCD).

October 2016

Page 22: In the descent-sequence illustration, Schiaparelli's altitude just before and at landing should be 2 m and 0 m, respectively.

Page 48: In the list of times for the Moon's occultation of Aldebaran, those for Phoenix should be p.m. and in Mountain Standard Time, that is, d: 10:13 p.m., r: 10:42 p.m.

Page 53: In the table of lunar data, the time for last quarter should be 19:14 (not 20:04) UT.

November 2016
