NGC1499 - California Nebula in Perseus
The California Nebula, NGC 1499 is an emission nebula in the constellation of Perseus. It is so named because it appears to resemble the outline of the US State of California on long exposure photographs. It is almost 2.5° long on the sky and, because of its very low surface brightness, it is extremely difficult to observe visually. It lies at a distance of about 1,000 light years from Earth.

NGC7635 - Bubble Nebula in Cassiopeia
NGC7635, the Bubble Nebula, Sharpless 162 is an emission nebula in the constellation of Cassiopeia. It lies close to the direction of the open cluster Messier 52, which can be seen at the top right of the image. The "bubble" is created by the stellar wind from a massive hot, young central star. The nebula is near a giant molecular cloud which contains the expansion of the bubble nebula while itself being excited by the hot central star, causing it to glow. It was discovered in 1787 by William Herschel.
