You are using a convenience method to construct the array, the
"arrayWithObjects:" method. This method returns an autoreleased array,
meaning that it will be deallocated automatically if you don't
explicitly retain it.

This should work better:

- (id) init
{
    self = [super init];

    if (self != nil)
    {
        GuideStar* guideStar1 = [[GuideStar alloc] init];
        GuideStar* guideStar2 = [[GuideStar alloc] init];
        GuideStar* guideStar3 = [[GuideStar alloc] init];

        guideStarArray = [[NSArray alloc] initWithObjects: guideStar1,
guideStar2, guideStar3, nil];

        [guideStar1 release];
        [guideStar2 release];
        [guideStar3 release];
    }

    return self;
}
