The #Fishhead_Nebula
IC 1795 - The Fish Head Nebula, also known as the Northern Bear Nebula, is part of a huge star forming system of gas and dust located along the Perseus spiral arm of our Milky Way galaxy.
The nebula is located in the constellation Cassiopeia approximately 6000 light-years from the Earth and is adjacent to the much larger Heart Nebula. The brighter region of IC 1795 is designated NGC 896 and is the home to many massive, young, stars.
Distance from Earth 6000 Light years.

I have photographed the Heart Nebula before, and was always curious and interested in the little appendix in the corner. It can easily be overlooked when looking at the much larger and impressive details of the Heart Nebula (see flic.kr/p/2qgwVE8). This time, I decided to spend some quality time imaging NGC896; I love the intricate patterns of dark dust clouds interspersed with brighter regions full of young stars.
In total, I've managed to acquire 27 hours of narrowband data, with both the Optolong L-Ultimate (3nm Ha & Oiii) and with the Antlia ALP-T 5nm Ha & Oiii filters. I used the ZWO ASI2600MC Pro camera, on an AM5 mount with ASIAir Plus. Processed with PixInsight + Affinity Photo 2.

I hope you like it and perhaps be inspired to spend some time imaging and/or admiring this somewhat overlooked but beautiful nebula.
Thanks for looking.

===== From Wikipedia ====
The Fish Head Nebula, or the Northern Bear Nebula, is part of a large star forming system of gas and dust located along the Perseus spiral arm of the Milky Way. The nebula is located in the Constellation Cassiopeia, approximately 6,000 light-years from Earth and is adjacent to the much larger Heart Nebula. The brighter region of the nebula is designated NGC 896 and is the home to many young and large stars. These stars radiate high amounts of ultraviolet light. This UV radiation excites the surrounding gas and causes it to shine at a high brightness.
The appropriately named Heart Nebula (Sh2 190), with its central star cluster (IC 1805), and the Fish Head Nebula (NGC 896) to its left, are large star-forming regions located in the Perseus Arm of the Milky Way. These regions lie between 6000 and 7500 light-years from Earth.
This image was taken with a RASA 8 telescope and ASI2600 MC Pro camera, with a IDAS NBZ II dual narrowband filter from Bortle 7 skies in Idaho Falls. The original 6080 x 4075 pixel image was downsized for posting.

The Fish Head Nebula, or the Northern Bear Nebula, is part of a large star forming system of gas and dust located along the Perseus spiral arm of the Milky Way. The nebula is located in the Constellation Cassiopeia, approximately 6,000 light-years from Earth and is adjacent to the much larger Heart Nebula. The brighter region of the nebula is designated NGC 896 and is the home to many young and large stars. These stars radiate high amounts of ultraviolet light. This UV radiation excites the surrounding gas and causes it to shine at a high brightness.
The supernova remnant HB3 (SNR G132.7+1.3) in the constellation Cassiopeia is one of the largest galactic SNRs currently known. Its physical size is reported to be about 60×80 pc, based on an assumed distance of 2 kpc.
In the sky HB3 extends to about 1°.5 × 2.0°, its age is given as about 30 000 years. In my image, the object appears as a shell-like structure with finely differentiated segments of energized Ha, SII and OIII.
The SNR is located directly northwest of the structure of the Fish Head Nebula IC 1795, i.e. in a frequently photographed region of the sky. In the image, approximately in the direction of 1 o'clock, the 1.0' small PN A66 can also be found. Furthermore, inside the SNR, at about 10 o'clock, the 0.5' small PN G132.8+02.0 shines.
The image is a composite of Ha, SII and OIII data for the background and RGB for the stars. As a photographic target, HB3 is quite challenging as it is very faint. I would have liked to invest a multiple of the shooting time, but the weather in western Germany in fall/winter 2023 is so bad that I gave up after half of the originally planned shooting time and started image processing. There was sometimes very poor transparency during the shooting nights and it was often very windy. A lot of data had to be discarded. I therefore needed 7 nights for the approximately 15 hours of total exposure time that remained.
This is a view of IC 1795 - The Fish Head Nebula, and is part of a huge star forming system of gas and dust located along the Perseus spiral arm of our Milky Way galaxy. The nebula is located in the constellation Cassiopeia approximately 6000 light-years from the Earth and is adjacent to the much larger Heart Nebula. This image was designed around the Hubble Palette of colors, splitting my image into artificial Sulfur II, Hydrogen Alpha, and Oxygen III channels. The image was then reassembled giving these hues that are typical of images from the HST.
Tech Specs: Sky-Watcher Esprit 120ED Telescope, ZWO ASI2600MC + Optolong L-eXtreme glass filter, running at 0F, 41 x 300 second exposures, Sky-Watcher EQ6R-Pro pier mounted, ZWO EAF and ASIAir Pro, processed in PixInsight. Image Date: September 16, 2023. Location: The Dark Side Observatory (W59), Weatherly, PA, USA (Bortle Class 4).
The Fishhead Nebula (NGC 896) resides just north of an extension of the Heart Nebula (IC 1805). Above the Fishhead Nebula is the Emission Nebula IC 1795. The Open Cluster labeled “Melotte 15 (Mel 15}” is embedded within the Heart Nebula.
Comet C/2017 T2 (PanSTARRS) is seen in Cassiopeia near the Fish Head (IC 1795) and Heart Nebula (IC 1805) on the evening of March 13, 2020. The image was made of a stack of 78 twenty second exposures taken with a Canon 70D (Ha modified) and a Canon 200 mm f/2.8L lens. (ISO 1000, f/3.5)

Heart Nebula (IC-1805), 07/10/2021
So on the second night of my last camping adventure to catch starlight I shot the Heart Nebula on a whim. Again, I have done this a few times before, but it was in a good location in the sky, and I wanted to try my new processing techniques on this one as well. This night went way easier than the night before and I was able to get some great data. It may be my favorite image to date and I’m pretty sure I will be making a big print for my wall.
The Heart Nebula is found in the constellation of Cassiopeia and is some 7500 light-years away. If you could see it with the naked eye, it would be almost ten times the size of the full moon in the night sky. The lower portion of the Heart Nebula has its own designation NGC 896 and is called the Fish Head Nebula.

IC 1795, also nicknamed the Fishhead nebula, is an emission nebula in Cassiopeia.
This is a bicolor image with a synthetic green from 10h45 min of OIII and 9h20 min of Ha. This image could benefit from SII as well, but I decided that I had already spent enough time on it.
Imaged with an Atik 460 through a C14 with 0.63 reducer riding on a Paramount MX.

拍得十分掙扎
光是三星就弄了好久...
原本還想測測看Flat 6A3最好的精後距
結果發現不管怎麼轉都很爛

看起來好是要買有附修正鏡的鏡子比較好
這種一體適用的

#IC1795 aka the #FishheadNebula is part of a larger star forming area 6000 light years from Earth. This image is comprised of 10 five-minute exposures made with my 715mmm telescope and a dual band filter to emphasize the hydrogen in the gas cloud. #StillLearning
On cloudy nights, I have been learning more about processing by revisiting some recent targets. The #HeartNebula is an emission nebula 7500 light years from Earth. This is my favorite target so far and I look forward to capturing more (better) data . The bright area at the bottom is the #FishheadNebula #StillLearning
