EquipmentTelescope and Mount: Celestron Compustar C14 with Astrophysics 0.75x focal reducer (f/8.25) Camera: SBIG STL 11000M with Baader Planetarium H-alpha, R, G, B filters. SBIG AO-L adaptive optics at 3.0 Hz. Exposures: H-alpha:L:R:G:B=600:80:160:160:160 minutes =19 hours:20 minutes total exposure.
DescriptionThe Elephant's Trunk Nebula, IC 1396a, is a small part of the enormous nebula and star cluster IC 1396 in Cepheus. IC 1396 is an HII region in the Milky Way lying 2,400 light years from Earth. The Elephant Trunk itself is a dense, dark globule within IC 1396 that is being illuminated and eroded away by a very massive star off the left side of the image. The massive star is also ionizing and compressing the rim of the Elephant's Trunk, causing it to glow brightly. Star formation is also occurring within the Elephant's Trunk. Solar winds from visible new born stars have cleared a circular region in the center of the globule on the left side of the image, creating the appearance of a curled elephant's trunk. Reflection nebulae are also present, creating colorful contrast.

EquipmentTelescope: TEC-140 Camera: QSI-583 Mount: Skywatcher NEQ-6 Exposures: H-alpha: 6 x 1800s (3nm Astrodon) OIII: 9 x 1800s (3nm Astrodon) SII: 3 x 1800s (3nm Astrodon) RGB: 3 x (4 x 600 s Astrodon True RGB) Total exposure time: 11 hours
DescriptionNGC 7000 is also known as the North America Nebula with the so called Gulf of Mexico. In this area the Cygnus Wall can be found. This part is the Mexican and Middle American part of the Nebula. It’s one of the most interesting parts of the nebula because this is a region of active star formation. Very near to the Wall a dark area (the Gulf of Mexico) can be seen that consist mainly of cold gas and dust, the ingredients for new stars. The wall actually is an ionization front where UV light from young stars ionize the cold hydrogen gas and make it glow in its typical red color.

DescriptionThe nebula complex around NGC 6559 sits next to its brighter Lagoon Nebula neighbor in Sagittarius. Mixed with emission, reflection, and dark nebula amidst a dense star field, this area has a rich diversity of color and detail.

EquipmentThe picture consist of raw frames/subs taken with LX200ACF 16" telescope and camera Atik 460ex mono. 16" telescope mounted on wedge.
DescriptionExposure time using Baader 1.25" filters: Ha=42*5min, OIII=42*5min, Lum=28*5sec+16*60sec, Red=66*30sec+35*2sec, Green=72*30sec+17*2sec, Blue=69*30sec+16*2sec. The picture shown is a composite picture made of above mentioned narrowband/lum/color stacks. The halo around NGC6826 consist of Ha and OIII information.
EquipmentCanon 60da, 135mm lens, Ioptron skytracker, tripod. 20'' exposure ISO3200
DescriptionA nebula and the landscape in a single shot without being a composite. For this shot I looked for an area without light pollution to get an horizon as dark as possible. Then I choose a 20 second exposure to get the landscape and the EtaCarina nebula in the same shot. I really like the end result, a nebula setting in the landscape in a single shot.

DescriptionBarnard 344 is a dark nebula in the constellation of Cygnus. It’s located close to the star Sadr in the Gamma Cygni Nebula. Barnard 344 is located on the bottom of the image. This region is very rich of dark and emission nebulae. On the image also VanDenBergh 130, a reflection nebula in this region, can be seen. LBN234 is an emission nebula glowing with hydrogen and sulphur.

EquipmentTelescope: Televue NP-127is on CGE mount Camera: Hutech modified Canon 450D (XSi) Exposure: 20 X 600s Hα, 21 X 300s RGB and 20 X 180s RGB subs at ISO 800 Composition: Each set aligned and stacked in ImagesPlus and results were combined in PS3.
DescriptionThe Horsehead Nebula is dark nebula in front of red emission nebula IC343. NGC2024 or the Flame nebula is to the lower left. There is also a blue reflection nebula, NGC2023 at the lower left of the Horsehead nebula. The bright star to the left and slightly up from the Horsehead, Zeta Orionis, is the center star of the three stars which makes up the "belt" of Orion.

DescriptionThe Propeller Nebula is an HII emission nebula in the constellation Cygnus. Not much is known about it. Information such as the source of excitation and distance remain undetermined. It is believed that its mass is quite low, probably less than 50 solar masses. There is obscuring dust associated with this peculiar structure, but seems to occur mostly in front of it. Designations for this nebula are DWB-111, Semeis 57 and MRSL 479.
