Hi,

 

This is an image of NGC 6164. It is a bi-color narrowband image taken with HA and OIII filters with RGB data for the stars. It is an emission nebula about 4,200 light years away in the constellation Norma. It is often mistaken for a planetary nebula due to its appearance. In fact it is an emission nebula by the hot O-type star in the center which is over 40 times more massive than our sun. The star is only 3-4 million years old and in another 3-4 million years it will end its life as a supernova.

Greg,

 

It is one of the southern hemisphere ones I got from my subscription with Martin Pugh.

NGC 3621

Bernard Miller
 

Hi,

 

This is an image of NGC 3621. It is a field spiral galaxy about 22 million light years away in the constellation Hydra. A field galaxy is one that is not a member of a galaxy group. This galaxy is about 93,000 light years in diameter, making about the size of our galaxy. I often have people ask me why we can see something this far away. The answer is this galaxy (and others) has a luminosity 13 billion times brighter than our sun. That is one very bright candle.

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.

Excellent detail but I like version B. Version C is unusually dark and data is clipped/lost.

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.

Arp 81 consists of NGC 6621 (UGC 11175 N, VV 247a and others) located above NGC 6622 (UGC 1175 S, VV 247b and others). Part of Arp’s Spirals with large, high surface brightness companions class, these are located approximately 310 million light-years away in Draco.

 

Luminance – 24x600s – 240 minutes – binned 1x1

RGB – 8x300s – 40 minutes each – binned 2x2

 

360 minutes total exposure – 6 hours

 

Imaged June 8th, 10th and 23rd, 2019 from Dark Sky New Mexico at Rancho Hidalgo (Animas, New Mexico) with a SBIG STF-8300M on an Astro-Tech AT12RCT at f/8 2432mm.

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.
