Messier 52 and the Bubble Nebula

Messier 52 is an open cluster located in Cassiopeia. It was discovered in 1774 by Charles Messier while he was observing a nearby comet. It is located in the lower-left of this image.

The Bubble Nebula (NGC 7635) is located to the upper-right of M52. The bubble is about 10 light-years across, and is being formed by a hot, young star whose stellar winds are pushing away the gas and dust of the nebula.

A little to the right of M52 is a sparse open cluster cataloged as Czernik 42.

A lot of the Bubble Nebula is not visible to my camera--most likely because the camera still has its factory-installed IR cut-off filter. Removing the filter is supposed to increase the camera's sensitivity in the lower-wavelengths of the visible spectrum.

California or Bust, Again

I've been wanting to retry the California Nebula (NGC 1499) since my last attempt. The opportunity presented itself the other night. The sky was beautiful! But, about a half hour into imaging, clouds starting rolling in and spoiled the party. Maybe I can try again another night. In the meantime, here it is:
