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, 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.

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!
