Date   
IC 5332

Dan Crowson
 

IC 5332 (ESO 408-9, PGC 71775 and others) is a faint face on spiral galaxy located approximately 33 million light-years away in Sculptor.

 

There’s a large cluster of galaxies at the bottom left. These are part of Abell 4010.

 

At -36 Dec, IC 5332 was only 21 degrees high on the meridian. Poor skies also contributed to the rough data.

 

Luminance – 12x600s – 120 minutes – binned 1x1

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

 

240 minutes total exposure – 4 hours

 

Imaged on September 29th, 2019 Dark Sky New Mexico at Rancho Hidalgo (Animas, New Mexico) with a SBIG ST-8300M on an Astro-Tech AT90EDT at f/6.7 603mm.

UGC 3294

Dan Crowson
 

UGC 3294 (PGC 17156 and others) is a spiral galaxy located approximately 185 million light-years away (https://iopscience.iop.org/article/10.1086/510201/pdf) in Orion. This one is a visual (and imaging) challenge due to the magnitude 6.52 (V) star HD 34959.

 

Luminance – 25x600s – 250 minutes – binned 1x1

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

 

370 minutes total exposure – 6 hours 10 minutes

 

Imaged October 28th, 30th and 31st and November 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.

Hi all:

NGC is a spiral galaxy in Ursa Major that's about 195 million LY distant:

http://www.greggsastronomy.com/IMAGES/ngc2998-LRGB.jpg

At the upper left are NGC 3009 and NGC 3010a,b,c.  Several other NGC objects are in the same field near 2998.  NGC 3002 is also cataloged as MGC+07-20-052 and appears as a distorted double galaxy (MGC+07-20-052 NED01, MGC+07-20-052 NED02).  In the map below 3002 is plotted twice; one is a star.  NGC 3004 is also just a star.

Hi,

This is an image of the Eta Carina Nebula. It is a complex of bright and dark nebula about 8,500 light years away in the constellation Carina. It is the home of many star clusters including Trumpler 14 and 16. Trumpler 16 contains WR 25, the most luminous star in the Milky Way, which can be seen near the center of the image. It is one of the largest nebulae in the night sky measuring over four times the size of the Orion Nebula. This images captured with 5nm narrowband filters (Ha, SII, and OIII) and processed with the Hubble palette.
