The image shows the red emission nebula Sh2-150 that is acompanied by the blue reflection nebula VDB 154 and some other interesting dark and reflection nebulas. The nebula is located about 2,900 ly away from earth in the constellation Cepheus .
The image was made with the data of my ASI294mcp (RGB) and my ASI1600mmp (Ha) attached to the 130/910 mm TS Photoline triplet apo with TSRED379 0.79x reducer.

VdB 16 is a small blue reflection nebula in the constellation Aries. It is illuminated by the 9 mag. star HIP 16170 with spectral class F. The nebulous region illuminated by the star is part of a large nebulous complex of gas and dust known as the Perseus Cloud. You can see some dark nebula as B 204. The distance to the Solar System is estimated 980 light years.

Another print from my first Vandyke printing session. This negative was actually made for cyanotype. After I found first black, made my chart, and determined a Vandyke curve, my printer ran out of ink. Since the chemistry was all set up, etc., I figured I would try some already printed negatives just for practice. This came out pretty well, I think.

van den Bergh 49 (* ome Ori, HD 37490 and many others) is the star and faint blue reflection nebula at the center of the image. Parts of the cloud further out are designated as LBN 894 and DG 70. vdB 49 is located between the head of Orion and M42.

Making the right choices is never easy, and when you think you, have you are probably wrong. Lyn decided not to go to the Yule Ball and instead used the time for reflection over the last year. As she walked the snow would slowly begin to fall into her open hand. Leaving a trail of solemn boot prints in the fresh powder that coated the school grounds, she sighed heavily.
With everything that she has faced, nothing prepared her for her fourth year at Hogwart's. She would have her first real crush, have her heart broken, have to learn that life was just not that fair. All lessons that young teenagers have to face. She had wanted to go to the ball but facing yet another dance alone, and people commenting on her eating habits, she opted to just use this time to think.
Decisions were made and she wanted to be better, she wanted to be stronger. If anything she had decided to make this her promise to herself for the new year. She regretted not going home to talk to her mum when she probably needed her most, but also realized the decision to stay and spend time with those who might not have had anywhere else to go was also the best decision she could have made at the moment.
In her mind her Christmas Wish was made and it was going to be up to her to keep it to herself.

Capturing 12.3 hours of luminance in the middle of summer is quite a task with as little as a couple of hours darkness a night, and that's when there's no moon about!
Started in May and finally I'm ready to begin capture of the red, green and blue to finish the colour image.

There is no sea on Earth large enough to contain the Shark nebula. This predator apparition poses us no danger, though, as it is composed only of interstellar gas and dust. Dark dust like that featured here is somewhat like cigarette smoke and created in the cool atmospheres of giant stars. After being expelled with gas and gravitationally recondensing, massive stars may carve intricate structures into their birth cloud using their high energy light and fast stellar winds as sculpting tools. The heat they generate evaporates the murky molecular cloud as well as causing ambient hydrogen gas to disperse and glow red. During disintegration, we humans can enjoy imagining these great clouds as common icons, like we do for water clouds on Earth. Including smaller dust nebulae such as Lynds Dark Nebula 1235 and Van den Bergh 149 & 150, the Shark nebula spans about 15 light years and lies about 650 light years away toward the constellation of the King of Aethiopia (Cepheus).

Vandyke brown toned in gold theo contact print from 8x10 film negative on COT 320.
Probably should try and do a better job, was a quick switch from another negative I was using which wasnt working, as they often do when using film negative.
Located in the constellation of Cepheus this is object 150 from the van den Bergh catalog (Sidney van den Bergh). A collection of very nice astro imaging targets.
