NGC 5871 is a star. Tempel claims to have seen four nebulae here, the other three being N5865, N5868, and N5869, all included in the GC. He has them in the form of a trapezium, and made a sketch, though he unfortunately did not publish it.
There are, in fact, only two nebulae in the area (see NGC 5865 = NGC 5868 for more on the identity). So, two of Tempel's objects are almost certainly stars (he has many other stars among his novae). Given the trapezium layout, and the NGC position (probably sent to Dreyer directly as it does not appear in Tempel's fifth paper), the star I've measured on the DSS is probably the correct one for NGC 5871. But there are other stars in the area that Tempel could have seen, so I don't want to insist that this is certainly his object. After all, I chose a different star while working on ESGC. Perhaps we can find Tempel's sketches some day and definitively locate some of his new "nebulae."
The RNGC (Sulentic and Tifft 1973) notes that this is a nonexistent object. Their coded description reads NF DC.
