Dan,

 

Back to the faint fuzzies I see 😊 Nice processing an a very faint object. Nice colors too.

Sharpless 198 (Simeis 5) is an emission nebula located approximately 7,500 light-years away in Cassiopeia. This nebula is often overlooked or imaged along with the more popular Soul Nebula (IC 1848).

 

Ha – 24x1800s – 720 minutes – binned 1x1

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

 

840 minutes total exposure – 14 hours

 

Imaged over nine nights in 2016 and 2017 at Dark Sky New Mexico at Rancho Hidalgo (Animas, New Mexico) with a SBIG STF-8300M on an Astro-Tech AT12RCT at f/8 2432mm.

Nice one Dan. I think with lasso and curves you could pull out more details in the core.

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.

Very nice galaxy cluster. The skies must be clearer over your observatory. I have no idea how you find enough clear skies for all these objects.

Subject: [DarkSkyNewMexico] Arp 105

 

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.

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.

NGC 6164

Bernard Miller
 

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.

NGC 3621

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.
