Imaged during a 3/4 moon.

In imaging this object in Ha, I was astonished at the brightness of the Ha emission coming from NGC281. It seemed quite dense and in only 8 subs, it produced a saturated image.

The gas of NGC 281 is ionized into high energy by the intense cluster contained within it, IC 1590. Bok globules are visible against the ionized gas. These globules are thought to be areas of condensation leading to new stars.
