This area of the sky is just beneath the leftmost star of Orion's belt (for northern hemisphere viewers). It is a very deep exposure in a very narrow specific wavelength of reddish light. This provides a very high contrast view of glowing hydrogen gas in the area. To the right is a feature known as the Flame Nebula, and in the middle you can see a small chessman looking horse outline, the horsehead nebula, formed by a region of dust blocking the light from the glowing gas behind it. This is the deepest image of this region I've ever acquired and there are a myriad of small details and subtle features I've never noticed before in my own or others photographs.

The Tadpoles (Narrow Band) The Tadpoles

IC 410 is an emmision nebula about 12,000 light years away in the constellation Auriga. The Tadpoles themselves are about 10 light years long...

This was shot over a two month period from October through the end of November 2014. All with the Veloce RH-200 and the Starlight Xpress Trius 694 camera. Baader narrowband filters were used for this Hubble Palette rendition. I used all three Paramount models at some point (ME II, MX+, and MyT) and collected all the data from my backyard in Lake Mary, FL.

The Bubble Nebula (Narrow Band) The Bubble Nebula

This is a synthetic RGB of the Bubble Nebula.

I collected 3.3 hours of SII data (20 minute subs), 3.6 hours of OIII data (20 minute subs), and 2.75 hours of Ha (15 minute subs). I tried making a Hubble Palette image, and for now gave up. Instead I made a synthetic RGB using the following formula (80% Ha + 20% SII) = Red. OIII = Green, 20% Ha + 80% Ha = Blue. I think it came out reasonably well.

Gamma Cygni - Take 2 (Narrow Band) Gamma Cygni - Take 2

In the middle of Cygnus the Swan, is the star Gamma Cygni. The area around this star is rich in hydrogen gas, and has a fair amount of ionized oxygen and sulfur as well. This image was captured with filters that pass only light emitted from these gasses.

It took three months as clear nights suitable for imaging are rare i nthe Florida Summer. I may well have spent more time processing this than I did imaging it over the months since, as I've been through several iterations and palettes, most of which I have discarded. Stretched appropriately, the Ha data will flood te entire frame. I toned it down a bit and so this is my "less is more" approach, but basically a Hubble Palette.

Rosette Nebula (Narrow Band) Rosette Nebula

Messier 31 is the well known great Andromeda Galaxy. Visible to the naked eye under clear dark skies, this galactic neighbor is 2.6 million lightyears away. It's a huge object, as wide as six full moons side by side, and contianing an estimated 1 trillion stars!

This object began my quest for the ultimate wide field telescope, as I was unhappy with having to take this with a piggy back mounted zoom lens. This is my first attempt with the Veloce.

Spider, Fly, and.... Crab? (Narrow Band) Spider, Fly, and.... Crab?

This is a busy wide field photo showing both IC 410 and 417. IC 417 is the lower of the two larger objects, and is called the spider, with a small fly visible below. IC 410 above contains the Tadpole nebula, which I think looks like the eyes of a large crab about to eat both the spider and the fly!

The Flaming Star (Narrow Band) The Flaming Star

IC 405 known as the Flaming Star Nebula. This portion of the larger complex shows the rippling gas and dust that gives the nebula is popular name. This region is rich in glowing hydrogen gas, as shown in this 6nm Hydrogen Alpha image. This nebula is approximately 1500 light years away.

North American and Pelican Nebula (Narrow Band) North American and Pelican Nebula

The North American and Pelican Nebula are classic wide field objects. 12 hours of data in narrow band wavelength, and I think this image better characterizes the true nature of the object. It often looks as if the shapes are "objects" in front of a star field, but in truth, they are "holes" in a dusty region allowing the glowing gass behind them to show through, in the shapes we see here.

Note: This image appears in the Readers Gallery of Sky & Telescope in the January, 2014 issue.
