This star field image has captured a span of 8×10° around the souothern region of Serpens Caput. A dimmed nebula in upper part with a size of 30×20 arc minutes is Sh2-33, and a southern stripe-shaped one has an ID of Sh2-24. Those nebulae have been estimated about 360 to 470 light years away, fairly close distance.
Moreover, you can detect a part of a vast reddish nebula of Sh2-27 surrounding zeta Oph in lower right hand side of the image.
