R & IW Carinae

Two interesting stars in the Southern Milky Way. R is a bright Long-Period Variable visible at most times with binoculars. It has a period of 308 days; not far away is an RV Tauri star, IW Car. This is peculiar in that the average brightness of the star also varies periodically. Observe IW Car once a week if you can.
