California Nebula

Inside the California Nebula Complex

Up Close & inside the California Nebula Complex.

The California Nebula (NGC 1499) is an emission nebula located in the constellation Perseus. It is so named because it appears to resemble the outline of the US State of California on long exposure photographs. It is almost 2.5° long on the sky and, because of its very low surface brightness, it is extremely difficult to observe visually.

The nearby energetic O7 star, xi Persei is responsible for the fluorescence of the nebula, due to excitation of the Hβ line. The California Nebula is also known as Sharpless 220 and is located about 1,000 light years from Earth. The California Nebula was discovered by E. E. Barnard in 1884.

This is my extreme close-up shot of it, literally looking inside near the center section the California Nebula Complex, you can also see the elusive black Jelly Fish, an opaque dark black molecular dust cloud near the bottom. A tremendous amount of details are visible within the California Nebula cloud..
I captured this image from my backyard observatory in Dayton, Ohio over 3 nights 09-17, 09-21, & 09-22 of 2017 of light gathering for a total of 7 hours & 15 minutes of exposure time, using my 6 inch diameter F5, Newtonian Scope & a ZWO 174MM cooled Cmos camera in HA, S2, O3 lines Mapped out to RGB.

NGC-1973-75-77 Reflection Nebula Complex

NGC-1973, NGC-1975, NGC-1977 Reflection Nebula Complex,
Nicknamed the Running Man Nebula,
It is located ~ 1460 light years away in the Constellation of Orion.

The Cloud is complex as there is a Red Emission region directly behind the dominant Blue Reflection Nebula,
the Nebula is reflecting Light from these young hot blue stars.
The region is abound with gas & dust clouds…NGC1973-75-77 is located 30 arc-minutes north of M42/M43 The Great Orion Nebula
NGC-1973, NGC-1975, NGC-1977 are the designations given for the 3 main parts of the Reflection nebula.

I captured this image on 10-26-2014 from my observatories at JBSPO in Yellow Springs, Ohio.

Canon 6 D DSLR & Home-built 16″ F4.5 Newt scope,
ISO 3200, for a 32 minute exposure, 8 x 240 second subs)

M42 & M43 The Great Orion Nebula Complex

M42 & M43 The Great Orion Nebula, an Awesome Stellar Nursery – Star Formation Region!  One of the most amazing objects to see through a telescope!  Who would like to explore this gaseous Cloud with me???
I pulled an all-nighter at my observatory using my Canon 6D DSLR attached to my 16″ scope ..and took lots of Data on many objects.
I’ll be processing images for weeks to come, but this one of M42/M43 in Orion was a two exposures stacked, one at 4 minutes for the outer regions and 1 at 30 seconds for the trapezium region.   ISO-3200, 10-26-2014 3:06am
and still working out my coma corrector configuration, also still a tad bit of vignette near corners with the large chip for this setup, but
I was amazed at what my new Unmodified Full Frame Canon 6D pulled out in less than 5 minutes through my Home-built 16″ Diameter F4.5 Fork Mounted Newt. Telescope. The camera seems to be more green blue sensitive than others, yet still able to record the red nebula regions well, and at higher ISO seems a lot cleaner (less noise) than previous DSLRs.
Although it did take me about 4 hours to carefully process it though!! Thanks to my winning the National Science Foundation/Discover Magazine/Astronomy Mag’s International Comet ISON Photo Contest, with the 1st place Award money I was able to buy this new camera a bit sooner than I had thought! ..Now I’m looking forward to many more quick and painless captures of the sky!Best Regards,

M42 & M43 The Great Orion Nebula Complex

M42 &M43 The Great Orion Nebula _ A stellar Nursery the closest to Earth. This star birth region is 1, 344 light years away
and is about 24 light years across.
The Orion Nebula is one of the most scrutinized and photographed objects in the night sky!!
My first Test of an Emission Nebula with my unmodified Canon 6D DSLR at the Prime Focus of my Home-built 16″ Diameter F4.5 Newt. telescope.
This is a quick 97 second exposure,
actually two shots layer Masked, to prevent over exposure!  A 7 second exposure for the center Trapezium region and a 90 second exposure for the full nebula is all it took to record this.
ISO was set at 3200. The Canon 6D tends to be a little more Blue/Green sensitive…a little noise in this image at 70F, but it does the trick if you need a quick image before the clouds roll in!!!
Transparency was not the best Friday night…but now I know it is easily capable of recording bright red Emission Nebula quickly!
Pretty impressive & sensitive for an unmodified DSLR.

This was just a test under poor sky conditions, so the next clear night I will go back and do a longer exposure & fully glory shot!
