Seagull Nebula – Three Panel Mosaic -Version 2

SEAGULLNEBULAASTROBIN5This nebula is now setting much earlier. I still need a little more imaging in the upper portion. Hopefully the next few days will offer an opportunity to complete the H-Alpha portion of this project. So far the total imaging time is about 15.5 hours.  It looks like a color version will have to wait until next year.

Horsehead and Flame Nebulae


From Wikipedia:

The Horsehead Nebula (also known as Barnard 33) is a dark nebula in the constellation Orion. The nebula is located just to the south of the star Alnitak, which is farthest east on Orion’s Belt, and is part of the much larger Orion Molecular Cloud Complex. The nebula was first recorded in 1888 by astronomer William Flemingon photographic plate B2312 taken at the Harvard College Observatory. The Horsehead Nebula is approximately 1500 light years from Earth. It is one of the most identifiable nebulae because of the shape of its swirling cloud of dark dust and gases, which bears some resemblance to a horse’s head when viewed from Earth.”

This image is a composite of 37 Luminance images for a total imaging time of 4.1 hours.  These sub exposures  were taken on the Takahashi FSQ 106 that is located at the Rowe, NM location.  The images were stacked and processed in Maxim DL, Pixinsight, and Photoshop.

Running Man Nebula and Orion

Via Wikipedia

“This object was named ‘The Running Man Nebula’ by Texas Astronomical Society member Jason Ware. Approximately 20 years ago his down stairs neighbor looked at the object and said it looked like a running man. He brought this up a TAS club meeting and the name stuck. Now widely accepted as ‘The Running Man’.”

The Running Man Nebula can be found at the top of this image, just above the Orion Nebula. A total of 42 H-Alpha images were taken with the Takahashi FSQ-106FSQEDX IV telescope and stacked. There were 20 ten second exposures, 20 sixty second exposures, and 6 thirty minute exposures.




Rosette Nebula – Enhanced Resolution


I love this particular section of the Rosette Nebula.  I have managed to increase the magnification and resolution by not using a focal reducer with the AstroPhysics 130mm refractor, and replacing it with a field flattener.  For the price of a slower speed and reduced field of view, precise higher resolution images are easier to attain.  In this configuration the speed is reduced to f6.3 with the field flattener versus about F5 with the reducer.  This stacked image is a combination of 15 thirty minute exposures for a total imaging time of 7.5 hours in H-Alpha.


Pacman Nebula – NGC 281

“NGC 281 is known informally as the “Pacman Nebula” because of its appearance in optical images. In optical images the “mouth” of the Pacman character appears dark because of obsuration by dust and gas…”

This was imaged through the Takahashi 4 inch refractor. It is a stacked composite of 52 thirty minute narrowband images (26 hours).


Pelican Nebula – Enhanced Detail

According to Wikipedia:

“The Pelican is much studied because it has a particularly active mix of star formation and evolving gas clouds. The light from young energetic stars is slowly transforming cold gas to hot and causing an ionization front gradually to advance outward.”

“Millions of years from now this nebula may no longer be known as the Pelican, as the balance and placement of stars and gas will leave something that appears completely different.”

Compared to my previous versions of this nebula, it is a little easier to see the pelican on the left hand side of this image due to the wider field of view that is a characteristic of the Takahashi FSQ106EDXIII telescope. It was captured in narrowband filters with 20 Sulphur, 17 Hydrogen-Alpha, and 16 Oxygen stacked images mapped to Red, Green and Blue as in the Hubble Palette.
