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.

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.


Tadpoles – Color

tadpolesastrobinThe clouds are moving in, so imaging on this nebula has ended. Three narrow band filters were used and were assigned RGB colors based on what is called the Hubble palette. This was tweaked by removing some of the green coloration while emphasizing blue. A total of 35 thirty minute images were stacked, for a total imaging time of 17.5 hours.

M33 – Triangulum Galaxy

It is a little easier to image galaxies since you can use simple RGB filters.  This was done with a Luminance filter and I plan to add the red, green and blue later.  M33 is a part of the local group of Galaxies which includes Andromeda.  It is “only” about 3 million light years from earth.  The total of the stacked exposures was about five hours.
