NGC 7635 - Bubble Nebula in Ha

NGC 7635, also called the Bubble Nebula and Sharpless 162, is a H II region emission nebula in the constellation Cassiopeia. It lies close to the direction of the open cluster Messier 52.
The "bubble" is created by the stellar wind from a massive hot, 8.7 magnitude young central star, the 15 ± 5 M☉[4] SAO 20575 (BD+60 2522).
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.

NGC 281 - Packman Nebula in Ha

NGC 281 is an H II region in the constellation of Cassiopeia and part of the Perseus Spiral Arm. It includes the open cluster IC 1590, the multiple star HD 5005, and several Bok globules. Colloquially, NGC 281 is also known as the Pacman Nebula for its resemblance to the video game character.

The nebula was discovered in August 1883 by E. E. Barnard, who described it as "a large faint nebula, very diffuse." The multiple star HD 5005, also called β1, was discovered by S. W. Burnham. It consists of an 8th-magnitude primary with four companions at distances between 1.4 and 15.7 seconds of arc. There has been no appreciable change in this quintuple system since the first measurements were made in 1875.

NGC 7380 - Wizard Nebula in Ha

NGC 7380 is an open cluster discovered by Caroline Herschel in 1787. It is also known as 142 in the 1959 Sharpless catalog (Sh2-142).
Known as the Wizard Nebula, this object is a reasonably large nebula located in Cepheus.

NGC 7380 is located in the constellation Cepheus about 7,000 light-years from Earth within the Milky Way Galaxy. The star cluster is embedded in a nebula, which spans some 110 light-years. The stars of NGC 7380 have emerged from this star-forming region in the last 5 million years or so, making it a relatively young cluster.
