IC1805: This is a large emission nebula, approximately 7500 light years from Earth, and about 200 light years across. It is known as the "Heart Nebula," because of its shape (if the field of this image were a little larger, the top of the heart would loop around just above where the top of this image cuts off). The bright part to the lower left of the image is NGC896 (the brighter half) and IC1795 (the dimmer half), a related emission nebula. This field of view is several times the diameter of the moon. It has been pointed out to me that toward the right of the image, just above center, is a tiny planetary nebula/supernova remnant, WeBo 1. This link will bring you to a cutout of the full resolution image of IC1805, showing this tiny nebula circled.
