Description:
A group of new and known variable stars in the field of the emission
nebula NGC 7635 was studied by Rosino, Bianchini, and Martino
(1976A&AS...24....1R 1976A&AS...24....1R)). In the source paper, approximate positions,
spectral types, and elements of variation were presented along with
finder charts for the thirty-two new variables. All but one of these
are now named variables. Although the positions provided are generally
accurate, they are not precise. For the fainter stars especially,
precise positions are required both for their recovery for further
study at the telescope and for linkage within other surveys such as
IRAS.
