Description:
The distance of the dark cloud L1251 was estimated from observations
made at the Konkoly Observatory between 1985 and 1991. The spectral
classification and the Hα emission features were measured on
objective-prism plates taken with the 60/80/180 Schmidt telescope;
the photometry was derived from observations made on photographic
plates with emulsion-filter combinations giving magnitudes in the
Johnson photometric system. The distance of the cloud was found to
be 300±50pc.
