Barnard’s Merope Nebula in the Pleiades Star Cluster

Barnard’s Merope Nebula (or IC 349) is located directly adjacent to the star Merope, often this area is heavily exposed burying this tiny object in the bright majesty of the Pleiades. It is listed as a 13th magnitude (visual brightness) nebula and is very close to Merope (about 0.06 light years). Merope is providing the dramatic lighting effects that you can see in the APOD link.

Tech Specs: This image is composed of 32 x 15 second images at ISO 3200 with five dark and five bias frames. Meade LX90 12” telescope, Celestron CGEM-DX and Canon 6D camera at prime focus. DSS and ImagesPlus for processing. Imaging was done on November 4, 2016 from Weatherly, Pennsylvania.

Antares and Rho Ophiuchi Cloud Region Wide-Field View

The Rho Ophiuchi and Antares dark cloud region is located in the constellation Ophiuchus just north of Antares and is one of the closest star-forming regions to our solar system. This image was produced using nine 30-second exposures using a Canon 6D with attached Canon EF 70-200mm f/2.8L USM lens, both mounted on an iOptron Skytracker mount. The lens was left wide open at f/2.8 and set at 70mm, images were stacked in DeepSkyStacker and adjusted using Adobe Lightroom. The image was heavily processed to coax out the nebula areas with the short exposure time. It also shows the planets Saturn (brightest point in the upper left) and Mars (the brightest point) as of April 14, 2016.

Dark Nebula in Aquila Barnard 142 and 143

This is a clip from a large Northern Milky Way panorama I’m working on, I thought this region was interesting. This is an area near the star Altair in the constellation Aquila and is referred to as Barnard 142/143, a dark nebula. Look in the dashed circle in the wide field image below and you will see an object that looks like a ‘C’ and another small dark region below it. Barnard 143 is the upper ‘C’ region and Barnard 142 is the lower. Now, look at these areas combined, can you see how they form the letter ‘E’? These two combined dark nebula are also referred to as the E Nebula or Barnard’s E.

Edward Emerson Barnard created the Barnard Catalog of dark nebula, the full name is  Barnard Catalogue of Dark Markings in the Sky. Probably the most famous is Barnard 33, the Horsehead Nebula.

IMAGE DETAILS – imaging was done in August 2015, this is a mosaic of images using a Canon 6D and Canon 100mm f/2.8L lens mounted on an iOptron ZEQ25GT mount. Each image in the mosaic was 10 x 60 second exposures at ISO 3200. LOCATION: Weatherly, PA.

This image actually has other Barnard objects, perhaps I’ll get time to focus in on several of these over the next few months.

The E Nebula is actually dark nebula in front of the stars of the Milky Way. The image below is a zoomed in area to show the E Nebula region, Altair is in the lower left. These areas used to be considered dark holes in the sky, but it is now understood they are dark molecular clouds.
