Messier 52 Star Cluster and NGC 7635 The Bubble Nebula
Messier 52 Star Cluster and NGC 7635 The Bubble Nebula
Messier 52 or M52, also known as NGC 7654, is an open cluster of stars in the northern constellation of Cassiopeia. It was discovered by Charles Messier on September 7, 1774. M52 can be seen from Earth with binoculars. (Wikipedia.org)
NGC 7635, also known as the Bubble Nebula, Sharpless 162, or Caldwell 11, is an 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, 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. It was discovered in 1787 by William Herschel. (Wikipedia.org)
Technical Information for This Image
This image was taken with a William Optics Zenithstar 81 APO Doublet Refractor on an iOptron CEM25P mount. The main imaging camera, attached to the prime focus of the telescope was a ZWO ASI294MC Pro cooled camera which was cooled to -5C. The exposures were 35x120 seconds at Bin 2x2. The gain was set to 120. Auto guiding was done using a William Optics 50mm guide scope with a 200mm FL. Attached to the guide scope was a ZWO ASI290MC camera which was connected to PHD2 autoguiding software. Capturing was done with Astrophotography Tool (APT) software and post processed with Pixinsight software with finishing touches put in using Adobe Photoshop Creative Cloud. Polar Alignment for the evening was done using SharpCap software.
