The Bubble Nebula, Caldwell 11, Sharpless 162

The Bubble Nebula Complex in Cassiopeia

NGC7635 The Bubble Nebula

Certainly my best shot of the Bubble Nebula complex to date!
Lots of detail in this one!
It is an enormous bubble being blown into space by a super-hot massive star!
This was a 10 Hours of exposure through Astronomik 7nm & 6nm Narrow Band data Mapped out to RGB. Captured over 3 nights from my backyard observatory in Dayton. 6″ Celestron Newt.,Coma Corrector, & ZWO 174mm Cooled CMOS Camera, Nebulosity, Pixinsight, & Adobe CS.
NGC 7635, also called the Bubble Nebula, Sharpless 162, or Caldwell 11, is a H II region emission nebula in the constellation Cassiopeia, The “bubble” is created by the stellar wind from a massive hot, 8.7th magnitude young central star, SAO 20575.
The Bubble is located in front of the HII Emission Region. It is located about 7000 to 11000 light years from Earth.

Impact Craters Tycho & Clavius

COLO has been busy!!!
The Chumack Observatory Lunar Orbiter…LOL!!! Okay not really an orbiter, but I can get very close-up detailed shots!
My backyard Observatory has made another pass over the Lunar Terrain, this time closing in on Tycho & Clavius (multiple impacts within the crater itself)!!!
I’m always looking for nights were I can improve on the resolution from the previous shots!
This week I will be posting some of my Sharpest images of the Lunar surface taken just this past Sunday evening from my backyard observatory in Dayton, Ohio!!!
Dodging Contrails and High Cirrus clouds…shooting in the clear spots.

Comet Jacques C/2014 E2 Putting on a Show!!!!

Here is my shot of Comet Jacques from last night 08-28-2014 from 05:19 U.T. to 05:42 U.T. Still very bright about 7th mag, looks good in Binoculars too! The Comet is up all night for us Northern observers.

It is currently moving through the Constellation Cassiopeia in to Cepheus and is Visible rising high in the North all night long now.

Comet Jacques C/2014 E2

08-28-2014 from 05:19 U.T. to 05:42 U.T. Taken at my Observatories & MVAS Dark Sky site In Yellow Springs, Ohio www.mvas.org

20 x 1 minute subs, unmodified Canon 6D, ISO 3200, Prime Focus of my Homebuilt 16″ Diameter Newt. Scope. I’m working on the movie, but that will come later. The faint tail shows up much better in a long exposure Stack, after stretching the 16 bit data in Maxim DL. I used StarStax in Comet mode to make this 20 minute exposure stack.
