Galaxy coordinates. II. Accurate equatorial coordinates for 17298 galaxies
Using images of the Digitized Sky Survey we measured coodinates for17298 galaxies having poorly defined coordinates. As a control, wemeasured with the same method 1522 galaxies having accurate coordinates.The comparison with our own measurements shows that the accuracy of themethod is about 6 arcsec on each axis (RA and DEC).
| Study of the open cluster IC 1805
Photoelectric magnitudes and colours in the UBV system have beendetermined for 169 stars in IC 1805. The reddening is variable acrossthe cluster. The distance modulus to the cluster is estimated at 11.7 m.Star-formation activities are still in progress in the cluster region.
