IMPORTANT !!! Purple stars in identification chart are so called 'non-star' objects in GSC; in dense fields the 'non-stars' are often real stars or blends of close pairs. Be careful about this. Close finding chart (prepared in GUIDE8): * occulted star is in center - labeled with cross * field is 3.0x3.0 degrees * limiting magnitude is 13.5 * labeled stars have indicated SAO numbers * remarks: Second chart shows 30' blowup to show correctly the star in field.
