Observatory Opportunity

Stanley Watson
 

Folks,
As most of you know the “Watson, Hanson, Ottum” observatory has three piers. One is Brian’s, two use my two scopes a 17’’ CDK and one a 24” CDK.
I am looking to sell my 17” CDK (most modern design), an A200 GEM PWI mount and pier, SBIG 16803 camera system with 7 place FW, with all Astrodon filters (L, R, G, B and Ha, Oiii and Sci 3nm). If you or a friend wants to join Brian, Mark and me in the building there are other goodies. A 24” flat panel system for flats for this scope, even in the day time. The building is very dark and nicely cool. I can throw in a new W10 computer with software, roof control, sophisticated surge and power system with fiber optics. Many other advantages. I want to brag a bit. This scope has performed spectacularly under Mark Hanson’s guidance. I also need to say that this is a very cordial and mature set of “partners”. We all share resources, rent for DSNM and have a fine time.

At the observatory level there are some nice features: the 20 ft by 30 ft main observatory/ telescope space, a 12 ft by 8ft storage area and a 20 ft by 8 ft computer room. We have AC to keep computers cool, Triplite heavy duty surge and battery systems, Hughes Satellite for emergency control of all of this.


So why am I doing this? I am focusing on my 24” PWI system, I find that this system takes too much time and energy from me.

Please feel free to email me privately (watsons@...) or call my cell (734 646 9425). Anyone you know who might fit in to this group, even outside the local peers, is worth talking to.

Thank you for considering this,

Stan Watson

NGC 300

Bernard Miller
 

Hi,

 

This is an image of NGC 300. It is a spiral galaxy about 6 million light years away in the constellation Sculptor. It is one of the closest galaxies to the Local Group and lies between the Local Group and the Sculptor galaxy. It is thought to be gravitationally bound to NGC 55. At about 94,000 light years in diameter, it is slightly smaller than the Milky Way.

 

Comments and suggestions appreciated.

NGC 6559

Bernard Miller
 

Hi,

 

This is an image of NGC 6559. This is a beautiful nebula complex of emission (red), reflection (blue) and dark (black) nebula about 5,000 light years away in the constellation Sagittarius. The nearby stars ionize the hydrogen gas to form the emission nebula and small dust particles reflect the star light to form the reflection nebula. Thick dust particles block out light to form the black dark nebula.

 

Comments and suggestions appreciated.

Sandqvist and Lindroos 17 (SL 17) - the Wolf Nebula

Bernard Miller
 

Hi,

 

This is an image of SL 17 (Sandqvist and Lindroos 17), also known as the Wolf or Fenrir nebula. Although there is emission nebula present in this image, SL 17 actually refers to the dark nebula that looks somewhat like a wolg. The name Fenrir comes from Norse mythology, meaning “the father of the wolves”.

 

Comments and suggestions appreciated.

M16 - The Eagle Nebula

Bernard Miller
 

Hi,

 

This is an image of M16, also known as the Eagle nebula. It is an emission nebula about 5,700 light years away in the constellation Serpens. M16 actually refers to the open cluster in the center of the image and the Eagle is formed by the surrounding nebula. This nebula contains the Pillars of Creation made famous by the Hubble image of the central portion of this nebula. You can see the Pillars of Creation in the center of this image.

NGC 6188 - The Great Wall of Ara (Narrowband using Hubble Palette)

Bernard Miller
 

Hi,

 

This is NGC 6188, also known as the Great Wall of Ara. It is an emission nebula and star forming region about 4,000 light years away in the constellation Ara. Just above the wall in the picture is the open cluster NGC 6193. This cluster is an infant in Astronomical terms being a mere 1 -3 million years old. The stars in this cluster are largely responsible for the emission nebula. The nebula spans about 600 light years.

 

Comments and suggestion appreciated.
