M33 - Triangulum Galaxy - Revised 11/1/2019

The Triangulum Galaxy is a spiral galaxy 2.73 million light-years from Earth in the constellation Triangulum.  It is catalogued as Messier 33 or NGC 598.  the Triangulum Galaxy is the third-largest member of the Local Group of galaxies, behind the Milky Wand and the Andromeda Galaxy.  It is one of the most distatn permanent objects that can be viewed with the naked eye.

Image is a stack of 48 two minute sub-images taken with a StarLight Express SXVR-M25C camera mounted to an Astro-Tech AT6RC scope with an Astro-Tech ATFF-2 field flattener.  Nebulosity v4.3 was used for capture, calibration, stacking, combining, color balance and noise reduction.  Final image processing was done in Photoshop CS5. The scope was mounted on a Celestron CI-700 using PDH2 v2.6.6dev2 autoguiding software with a Meade DSI Pro camera mounted on an 80mm guide/finder scope.  Images were taken at the 2019 Okie-Tex Star Party near Kenton, OK.

Imaging Setup used at Copper Breaks State Park in November 2018

The mount is a Celestron CI-700 with Sky Commander push-to setting circles.  The imaging scope is AstroTech AT6RC (6 inch f9) with field flattener.  The imaging camera is a Starlight Xpress SXVR-M25C.  The guide scope is an 80mm f7 refractor.  The guide camera is a Meade DSI Pro.  Guiding software is PHD2.  Imaging software is Nebulosity 4.  The mount was polar aligned using a QHY Polemaster.

NCG7635 - Bubble Nebula - 20181106

 

 

 

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.

The image was taken November 6, 2018 at Copper Breaks State Park near Quanah, Texas.  The imaging camera was a Starlight Express SXVR-M25C through an Astro-Tech AT6RC mounted on a Celestron CI-700 mount and tripod.  The image was guided using PHD2, a Meade DSI Pro camera through a 80mm F7 scope. The images is 60 minutes (6x10 minutes) pre processed with Nebulosity 2.4.  Final processing was done using Photoshop 5.5.  This is the first image I have posted with the new to me Starlight Express camera.  The camera temperature was adjusted for -10C.
