Although Delta is an easier star to see, its magnitude range of 3.6 to 4.3 is less noticeable than U Cephei, which ranges from 6.8 to 9.2 magnitudes. U is the southernmost of this group and if glowing at its brightest it will outshine the other three. If at its dimmest, it will fall short of the others. Its period is about 2.5 days and takes only 8 hours to dim and return to normal after spending 2 of those hours in its eclipsed phase. The finder chart below indicates magnitudes without the decimals.
North is left, south is to the right.
Now, point your scope to Mu Cephei. This is an irregular variable with fluctuations spanning hundreds of days, but it always remains visible to the naked eye under suitable conditions. It forms a wide triangle with Alpha and Zeta Cephei, and if you have the patience, you may notice its variability from magnitude 3.7 to 5.0. As a point of interest, Mu is the north polar star of the planet Mars. NGC6946 is a magnitude 11 spiral galaxy of about the same size to the southeast.
