Scintillation

Scintillation, also known as twinkling, refers to the change in brightness and color of stars through the atmosphere. If you have ever looked in the night sky and noticed twinkling stars, that was a result of turbulent atmosphere, small changes in the wind speed, temperature, and pressure. These small changes produce small changes in the refractive index of the air, which causes different wavelengths and intensity of light to enter our eyes - in the same way as light changes directions when it enters a swimming pool. This image showcases that effect and it was created my moving the camera around during a long exposure of a particular celestial object. Notice the differences in line width and color between the stars and planets.

M45

For the first time since I got this telescope 3 years ago, I decided to give it a go at deep sky astrophotography. Unfortunately, part way through the night frost formed on the lens and I did not notice it in time. So 18 of the 29 frames used to create this image were not of the best quality. Still, I think it was a good first test.

North American Nebula Complex

"The North America Nebula is large, covering an area of more than four times the size of the full moon; but its surface brightness is low, so normally it cannot be seen with the unaided eye. Binoculars and telescopes with large fields of view (approximately 3°) will show it as a foggy patch of light under sufficiently dark skies. However, using a UHC filter, which filters out some unwanted wavelengths of light, it can be seen by the naked eye under dark skies. Its prominent shape and especially its reddish color (from the hydrogen Hα emission line) show up only in photographs of the area. Cygnus's Wall is a term for the "Mexico and Central America part" of the North America Nebula. The Cygnus Wall exhibits the most concentrated star formations in the nebula. The North America Nebula and the nearby Pelican Nebula, (IC 5070) are in fact parts of the same interstellar cloud of ionized hydrogen (H II region). Between the Earth and the nebula complex lies a band of interstellar dust that absorbs the light of stars and nebulae behind it, and thereby determines the shape as we see it. The distance of the nebula complex is not precisely known, nor is the star responsible for ionizing the hydrogen so that it emits light. If the star inducing the ionization is Deneb, as some sources say, the nebula complex would be about 1800 light years distance, and its absolute size (6° apparent diameter on the sky) would be 100 light years. The nebula was discovered by William Herschel on October 24, 1786, from Slough, England." = Wikipedia Location: Fox Park and Pawnee National Grasslands, CO Date: 2011-07-28, 2011-07-28, 2011-07-29, 2012-07-20 Camera: Canon XSi (modified) Lens: Canon 200mm f/2.8L Guide Scope: AT66ED Guide Camera: Orion Solitaire Auto-Guider Mount: GCEM Filter: Astronomik EOS Clip-Filter H-alpha CCD Shot: (HaR)RGB HDR 5x1 minute f/4 ISO 1600 7x5 minute f/4 ISO 1600 37x10 minute f/4 ISO 1600 19x10 minute f/2.8 ISO 1600 (Ha) Darks, Flats, Dark Flats Applied Processing: Photomatrix Pro, PTGui, Deep Sky Stacker, Nebulosity 2, Photoshop, Topaz
