NGC2467 in Hubble Palette

Posted By Roland Christen
This very faint nebula was imaged remotely with the 12" Mak-Cass astrograph at Las Campanas. Data was very limited with only 3x600 seconds exposures for the 3 narrowband filters. This is our first try. We will revisit this object in the coming weeks.

Pacman nebula

NGC 281 in Hubble palette, taken at Mount Wilson with 12" F8 Astro-Physics Mak-Cass astrograph. 6 x 1200 seconds H-a, OIII, SII.

Is that a little mouse in the middle?

Another image taken with 12" F8 Mask-Cass astrograph
Inner part of the galaxy is 1 x 300 second LRGB, outer extent of the galaxy is 15 x 300 seconds L and 7 x 300 seconds RGB.

IC2872

Posted By Roland Christen
The whole area is called Rodgers 60. We here at AP are calling it the Angry Duck with Nest and Egg.

A very faint nebula that really needs 8 hours exposure or more to bring out all the faint stuff around the periphery.

8x600 sec SII, H-a, OIII mapped to RGB.

Zodiacal light

Posted By Roland Christen
On my recent trip to Hawaii Island I had a chance to observe the winter skies from Mauna Kea, site of world famous observatories. The winter Milky Way was very prominent, but what really stood out was the Zodiacal light which stood high in the western sky, reaching almost to the zenith. This is just a 5 second exposure taken with an 18mm wide field lens on my Sony digital camera.

Winter Milky Way from Mauna Kea

Posted By Roland Christen
I apologize for the poor quality of this image, but having only a wiggly tripod presented some challenges in putting this mosaic together. The image consists of 7 frames and covers the entire visible Milky Way from the southern end all the way to the north where the high peak of Mauna Kea cut off the most northern part.

Each frame was 5 sec exposure with 18mm lens, Sony digital camera with APS size sensor. Caught a nice meteor near Orion, one of many that I saw that night - Feb 25, 2014. The image was taken near the visitor center at the 9000 ft level below the world famous observatories (Keck, Gemini North, Subaru, etc). South is to the left (traffic and lights from the visitor center can be seen far left).

Fire in the sky

Posted By Roland Christen
During my visit to Hawaii we drove over to the famous volcano. The night was clear and you could see the stars beyond the fuming smoking cauldron of Halemaumau. It was an otherworldly view for sure.
