NGC 2353 & NGC 2343
NGC 2353 & NGC 2343 (along with NGC 2351) are open star clusters within the image. The image itself was embarked upon as the general area presented itself "in the right place at the right time". Not often imaged except as perhaps part of an extremely wide field view, I thought it worth doing - the interaction between the Ha & OIII gasses (along with some darker dust areas) & clusters make for an overall interesting image. There is some SII gas in the area - but not very much. There is also a very faint and tiny planetary nebula within the image - if you don't see it, it is marked on the annotated image below. (PK225+00.1).
