Dust in backlit galaxies: Properties of the foreground systems in NGC 3314 and NGC 1275
Description
New digital imaging of NGC 3314 and NGC 1275 is presented. NGC 3314 consists of an Sc galaxy in front of an Sb; BVRI data are used to estimate the extinction through and between spiral arms and derive R = 3.5 for the extinction curve, with large uncertainties due to structure in the foreground galaxy. Dust lanes are identified in NGC 1275, of optical depth similar to those in NGC 3314, and occurring in association with giant H II regions; these imply a type Sc or Scd for the foreground object. This object lies outside the low-velocity filament system and is probably not interacting with the main body of NGC 1275
