Dan Crowson
 

Sharpless 209 is an emission nebula located approximately 29,000 light-years away in Perseus.

 

Luminance – 24x600s – 240 minutes – binned 1x1

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

 

360 minutes total exposure – 6 hours

 

Imaged January 3rd, 24th and 25th, 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.

I also captured 20+ hours of Ha but it didn’t really add anything to the image.

Arp 105

Dan Crowson
 

Arp 105 (the Guitar or I’d call it the Geyser) consists of three galaxies in Arp’s ‘E and E-like Galaxies – Connected to Spirals’ class. The top galaxy with the plume is NGC 3561A (NGC 3561N, VV 237c and others). The middle galaxy is NGC 3561 (NGC 3561B, UGC 6224, VV 237a and many others). The bottom galaxy ‘area’ is known as Ambartsumian’s Knot (VV 237b and others). These all appear to be approximately 412 million light-years away in Usra Major.

 

While not on Arp’s list, NGC 3550 (UGC 6214 and others) appears to be the result of something that was probably really bad in the past. This is the large galaxy near the center top that appears to have three bright cores.

 

Most, if not all of the galaxies in this image are part of the Abell 1181 Galaxy Cluster.

 

Luminance – 24x600s – 240 minutes – binned 1x1

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

 

360 minutes total exposure – 6 hours

 

Imaged March 31st and April 2nd and 3rd, 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.

vdB 136

Hi all:

vdB 136 is a small reflection nebula in Cygnus.  It is illuminated by a bright yellow star with lots of emission nebulosity in the background.  I was hoping to add some Ha but the monsoon clouds seem to be hovering over southwest New Mexico.

NGC 7424

Bernard Miller
 

Hi,

 

This is an image of NGC 7424. It is a barred, grand design spiral galaxy about 37 million light years away in the constellation Grus. It is about 100,000 light years in diameter, making it about the same sixe as the Milky Way galaxy. The reddish central core indicates presence of older stars, while the blue spiral arms indicate ionized hydrogen and clusters of younger stars.

 

Comments and suggestions appreciated.

Hi Bernard
That really is a “galaxy of a different color”.   I don’t recall many other spirals with such distinctly blue arms.  Thanks for sharing.

Re: Arp 105

Dan Crowson
 

Bernard, it’s that 300 feet that makes all the difference. J

 

We open when it is a bit windier than you can probably deal with. My scope is shroudless and it makes a huge difference if there’s any kind of wind. We also tend to look at the all-sky because there are a lot of times when the forecast says clouds and the sky is clear. Case in point is that the best skies all year (for me) were the night of 7/7 morning of 7/8. CSC showed seeing of something like 2/5.

NGC 6357 - The Lobster Nebula in narrowband

Bernard Miller
 

Hi,

 

This is an image of NGC 6357, also known as the Lobster Nebula, taken with narrowband filters and processed using the Hubble palette. Although known as the Lobster nebula, the FOV of this image is too small to see then entire nebula, so finding the lobster will be difficult without pharmaceuticals 😊. It lies about 8,000 light years away in the constellation Scorpius. This nebula is home to open star cluster Pismis 24, which has some of the most unusually bright and massive stars in the galaxy. The intricate patterns are caused by complex interactions between interstellar winds, radiation pressures, magnetic fields, and gravity.

 

Comments and suggestions appreciated.
