The wide binary 32 Camelopardalis (Struve 1694) can be seen with a small telescope. The wide double can easily be split at 50x, and shows two blue white stars of roughly equal magnitude (A (HD 112028) = 5.28; B (HD 112014) = 5.85) about 21" apart. Both stars are located 3260 (300?) light-years a...
