Queen guitarist Brian May and David Eicher launch new astronomy book. Last chance to join our Costa Rica Star Party! Learn about the Moon in a great new book New book chronicles the space program. Dave's Universe Year of Pluto. Groups Why Join? Astronomy Day. The Complete Star Atlas. For this sketch of open cluster NGC , the author changed the setting of her zoom eyepiece to 8mm x.

For both sketches, she used white printer paper with a black felt-tipped pen for the brightest stars, a 2 pencil for medium-magnitude stars, and a 0.

Both sketches have north up and west to the right. After inverting the scanned version of my sketch in Photoshop, the next step was to reduce the bloated appearance of the stars so that the smallest would appear faintest. Starizona Action Pack - The Starizona Astronomy Action Pack for Photoshop is a set of actions that can be used to quickly and easily enhance your deep-sky astrophotos. Astra Image - Astra Image gives you everything you need to make your images sharper, clearer, more amazing.

With a clean, easy-to-use layout and intuitive tools, you will be making better photos in no time. Available as an application and Adobe Photoshop plug-ins. Sequence Generator Pro: How to get started using Sequence Generator Pro and how to setup your equipment and use its features.

Problem solved! Sometimes stars can come out a bit larger than you'd like in an image. This action reduces star size, which can help make an image appear more crisp. Handy tip : This action actually affects the entire image, and can help smooth the image as well as reducing the star size, but it can be limited just to the stars by running the Select Brighter Stars action first, then running Make Stars Smaller, then running Per Selection Only.

If you look closely at the best astrophotographs on the web, you begin to realize that the top astrophotographers leave their images a little fuzzy for a more real, 3D appearance. This helps bring out star color and avoids dark halos around stars.

The Less Crunchy More Fuzzy action not only smoothes out star edges, but also helps clean up dark, crunchy-looking noise in your deep sky objects, giving the image a less processed, more natural appearance. Per Selection Only action. This allows you to be more aggressive in sharpening your deep sky objects then bring the stars back to looking natural.

Many cameras, when pushed near their limits to detect dim objects, will produce pattern noise in their images, seen as horizontal or vertical stripes or banding. This is sometimes also referred-to as readout noise. Up to now one has either had to try to hand-edit this out, or just not stretch the luminance levels so far as to make the banding appear out of the background, losing precious dim detail.

With the innovative Horizontal and Vertical Banding Reduction actions in this set this noise is history in a matter of seconds, allowing you to bring out the faintest details in your images. Handy tip : If your image has strong horizontal banding, and you run Horizontal Banding Reduction, you may see remnant vertical banding that was hidden before.

You can then run Vertical Banding Reduction and end up with a pattern-free image! Sometimes you find yourself having stretched the levels and sharpened an image so much that the cores of the larger stars are burned out to white, leaving the star field less colorful looking than you'd like.

The Increase Star Color action is perfect for fixing this. There is very likely some color information around the edges of those hot white stars, and this action pulls that color back into the star centers for an overall more visually pleasing appearance. Digitally-captured images, because of the necessity to convert from linear to gamma-corrected representation i.

What if you had a way to do noise reduction in just the darker parts, while avoiding oversoftening details in your galaxy or nebula? Now you do! Handy tip : Sometimes you want to remove noise from only the very darkest parts of the image, to preserve the most detail in dim nebula or galaxy images. Deep Space Noise Reduction provides an even less aggressive noise reduction that really makes your image look cleaner.

One kind of noise digital imagers deliver is color noise. One mistake many people make is to try to eliminate color noise by using a luminance noise reduction method. This can end up making an image look overprocessed and flat, losing important detail yet leaving much of the color noise intact! Color Blotch Reduction , which also appears in my dSLR Tools set for general photography, finds the most visible color noise in open areas and eliminates it, while avoiding damage to the detail in the objects in the image.

Handy tip : If you have both color and luminance noise, chances are removal of the color noise will make it less necessary to do aggressive luminance noise reduction. Run Color Blotch Reduction first, and then judge the level of luminance noise to remove. You may have to do less than you think.

If you've captured subtle detail in your deep sky object, this action can help you make it more visible, without affecting the overall balance of the image. Local Contrast Enhancement , which also appears in my dSLR Tools set for general photography, is a more sophisticated form of local contrast enhancement than you may have read about on the photo retouching sites, because it emphasizes darkening more than lightening.

Handy tip : Use Local Contrast Enhancement to eliminate a "foggy" look. At some point in astro image processing one usually "stretches the levels" - lightens up an image in layman's terms.

This action actually isolates the brighter stars and lightens only the dim deep sky object and the dimmest stars in the image, resulting in a lighter image in which the stars are kept small and tight. Handy tip: If an image needs a LOT of brightening, often a combination of this action and the Curves function will give the most natural looking result, while still keeping bright star sizes small.

Occasionally you'll get to a point in your editing where you'll say, "Gee, if my nebula or galaxy were a little brighter, and the stars a little dimmer this image would be better. This is precisely the action to run if you have stars that are a bit too bright and distract from the subtle dim detail of your deep sky object.

Handy tip: When you think you're done with an image, try running this action on it. Chances are it will make an overall visual improvement. When viewing black and white images taken through filters - for example the commonly used Hydrogen Alpha filter - I often found myself wondering what the object would look like if presented in the actual color of the filter.
