Horsehead Nebula (IC 434)

It is a now a good time to image and visually observe the Orion Nebula since it can now be found in the Eastern sky.  For those with binoculars, Orion is an easy target. The Horsehead Nebula is located just to the south of the star Alnitak, which is the star that is farthest east onContinue reading “Horsehead Nebula (IC 434)”

BUBBLE NEBULA – HALLOWEEN VERSION

I was surprised to see the gremlin’s face when I processed this image of the Bubble Nebula (NGC 7635). This was obtained by stacking about 13 hours of exposures (39×10 minutes and 28×15 minutes) taken with the Astro-Physics f6.3 130mm refractor in combination with the QSI 690 camera. My Astro-Physics mount is getting more accurateContinue reading “BUBBLE NEBULA – HALLOWEEN VERSION”

PROPELLER NEBULA (DWB111)

The Propeller Nebula is a very faint emission nebula in Cygnus. This is a stacked group of 30 five minute exposures in H-Alpha and 30 five minute exposures in O3 for a total exposure time of five hours. It was taken through the Astro-Physics 130mm Starfire Refractor and the QSI 690wsg camera.    

PELICAN NEBULA

With the improving weather I was able to finish this off. The benefits of longer exposures are starting to pay off. The image is a stacked composite of 90 five minute narrow band exposures taken through the Astro Physics 130MM Starfire refractor for a total exposure time of 7.5 hours. It was processed in MaximContinue reading “PELICAN NEBULA”

My first 30 minute sub exposure of the Horsehead Nebula.

Taken in HA and processed in pseudo color in Photoshop. This single exposure was taken with the QSI 583wsg camera on the Celestron C11 EdgeHD at f7. An updated photo that shows the impact of stacking a few additional narrowband images.
