-this binary splits into two components in the triad, one reaching 3.7mag (yellow) and the other 6.3mag (orange). The components are 96.3" apart, separated by about 29 light years from Earth. The star belongs to the motion cluster of the Big Dipper.

-this luminous red giant is a semi-regular variable star whose brightness varies between 0.4mag and 1.3mag over a period of about 5.7 years. However, it is more orange in colour in the triad. Betelgeuse is one of the largest stars visible to the naked eye. If it were at the position of the Sun, its edge would extend to the asteroid belt. It lies 500-600 light years away.

-a semi-regular M-type variable star, appearing bright red when observed through a triad. It shows small, irregular magnitude changes, from 4.8mag to 5.2mag with a mean period of about 24 days. Because of its proximity to the celestial pole, it can be observed throughout the year from more northerly latitudes.

-the brightest star in the constellation is 4.25mag, in many constellations it would go unnoticed. In the triad, we can see its orange to red hue. Its spectral class is K4, so it's a cooler star than our Sun. Its brightness probably fluctuates slightly and it's 370 light years away.

-a wide binary star whose 4.4mag and 5.5mag brightness components are 7' apart, so we can distinguish them with the naked eye. In the triad we can see their different white and orange hues. It is an optical binary: the brighter component is 364 light years away, the fainter one is 10 light years closer. However, the brighter component is actually a very close physical binary, which can only be resolved with a large telescope.

-The name means "southern claw" and recalls the origin of the constellation. It is a very easily distinguishable double star, for which even a viewable telescope will suffice. At the main component of 2.75mag, there is a companion of 5.8mag at a distance of 231". In the triad it is a bright wide pair consisting of a white and yellow component. Since both stars show the same proper motion, this is probably a true stellar pair. Its distance from Earth is 75 light years.

-Dark yellow giant, semi-regular variable star of the RV Tauri type, one degree south of β Scuti (4.2 mm). Its brightness varies from 4.9mag to 8.2mag over a period of five months - a main period of 140 days. The cause of the deep minimum may be carbon particles formed in the star's atmosphere. It is within range of the triad, being the brightest variable star of the RV Tauri type: it appears to oscillate in at least two overlapping periods, and at its maximum it is at least 8,000 times more luminous than the Sun. It often changes brightness between 5-6mag, but after four or five such cycles it drops to 8th magnitude. It is about 2,500 light years away. Similar stars have been found not only in parts of the Milky Way, but also in globular clusters, whether in the very centre of the Galaxy.
