WIZARD NEBULA NGC 7380 (GUIDED)

Happy Halloween! In this version of the Wizard Nebula I increased the sub-exposures from 15 minutes to 30 minutes which required guiding. I then stacked 11 images. This increased the resolution substantially. The wizard nebula is a cloud of interstellar gas and dust that lies about 8000 light-years from us. In a telescope you wouldContinue reading “WIZARD NEBULA NGC 7380 (GUIDED)”

WIZARD NEBULA – NGC 7380 (unguided)

This is another Halloween treat. Can you see the Wizard in this image of the Wizard Nebula? The total exposure time was about 6 hours through an H-Alpha filter. I will be working on a color version.

BUBBLE NEBULA (COLORIZED)

This is the result of stacking an additional five hours of SII and OIII narrowband images with the H-Alpha images that were used to produce the black and white version.

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”

Andromeda (M31)

Andromeda Galaxy(M31) taken with a Williams Optics Star 71 (71mm) telescope. The camera was the QSI 583wsg. It is a composite of 55 five minute images taken with luminance, red, green, and blue Astrodon filters.

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”

PELICAN NEBULA – Work in Progress

Well, the weather is turning bad, so I don’t know when I will be able to add data to this narrow band photo of the Pelican Nebula. I would like to add a little more color and some more detail. So far I have stacked 10 five minute H-Alpha images and 10 five minute OIIIContinue reading “PELICAN NEBULA – Work in Progress”

A Messier Miss in Leo – NGC 2903

This is one of the better objects missed by Charles Messier in the preparation of his list of objects to avoid when searching for comets. Located in the constellation Leo it is around 31 million light years away and has the luminosity of 19 billion suns. It has been adorned with festive star spikes justContinue reading “A Messier Miss in Leo – NGC 2903”
