H{alpha}-emission stars
Listed in IVOA Registry (Virtual Observatory)
The catalog includes 731 early-type stars (non-banded spectra) and 34 late-type stars (banded spectra) showing H{alpha} in emission which were not previously known as emission-line stars.
Description
Description (by B. Skiff): This is a rough working list of accurate coordinates for MacConnell's 1981 list of H-{alpha} emission objects. The original catalog is made of 2 tables: table I with the early-type stars, and table II with the late-type stars.
A few objects were not recoverable, either due to gross position errors or simply from plate flaws or something similar. Many cases were verified using the SuperCOSMOS H-{alpha} emission survey images. MacConnell's magnitudes are replaced with much better V data mainly from ASAS-3.

The original magnitudes have a scale error at the faint end (the faintest "11.9" stars are typically mag 13 to 14), and are generally rather scattered.
