Degrees, minutes and seconds are all measurements of angles in the sky. Strictly speaking they are degrees, minutes and seconds of arc. The Moon is about half a degree across. When it comes to sizes smaller than a degree, we use minutes, with 60 minutes to a degree written 60′. So the Moon is about 30′ across it varies a bit over the month. The planets are a lot smaller, and their sizes are measured in arc seconds written ″. Jupiter is generally the largest, and varies from about 30″ to 45″. Mars never gets bigger than around 25″, and is usually a lot smaller, while the outer planets are only two or three arc seconds across.

Notes:

STRUVE 163.

Struve 163 is a binary double star, orange and pale blue, with 34 arcseconds separation, close to Epsilon Cas, the most NW star in the . In binoculars, I found it embedded in a very interesting and lovely field of asterisms, chains, and optical doubles, with subtle color variations among a few orange stars.

The entire field is best seen with about a 4 degree FOV. Approx 1 degree west of Struve 163 is string of five stars, the middle of which is fainter at 9.1 but still visible in the binocs. The fourth one going west to the east is an optical double SAO 12080/12082. Add to these 5 stars another star 25 arc minutes to the southwest, 53 Cas, which forms the head of an equalatorial triangle. The southeastern point of this triangle is V781 Cas, a pulsating orange- red variable at 7.5 magnitude. These eight stars form a lovely asterism.

North of this asterism, and in between it and Struve 163, is another lovely chain of 5 stars, the middle of which is TYC 4040-0902-1, a 9th magnitude orange-red star. The 5th of these is 10 arcminutes to the east of the line of four, and forms the crescent ring that completes this asterism. Finally, NE of this asterism and 10 arcminutes to the southwest of Struve 163, is a standout, isolated optical double SAO 12016/12017 with 1 arcminute separation. 12017 is itself a double, a probable binary, but the 12th magnitude companion is hard to see, with only 2 arcseconds separation.

There are other chains and asterisms visible in the area.I recommend viewing the whole thing in a 4 degree FOV initially (i.e., 16x binoculars or rich-field telescope), then gradually magnify it to see the details described above, and to split Struve 163. 163's 'B' component, pale blue next to the primary's orange glow, is almost visible at 23x in my 70mm binoculars. In my 8", F10 SCT, all four components of the Struve 163 system are visible under good seeing conditions (14mm eyepiece, 150x). Struve 163 is also designated as HD 11092, SAO 12006, HIP 8626, and is also listed in the Washington Double Star Catalog.
