This is a relatively obscure nebula, but can be seen in a scope as small as 80mm if you know what to look for. NGC 7023 or the Iris Nebula, as it is commonly called, is a hot blue star surrounded by a dusty dark nebula cloud. The star peeks out at us through a hole in this cloud, giving this deep sky object a unique appearance.
This image is 7 ten minute exposures taken with my 300D through my Orion 100mm F6 achro refractor. All shot at ISO 800. It could use some more exposure time, but my battery died and so far the weather has not cooperated.
