M42 by Alex Shvonski

This image is a combination of many different exposures. I took 30 one second exposures of M42, which were combined to make one clear image that was very crisp. I then took one 30 second coloured image with each of the 3 different filters. In maxim dl, these images were first combined, then screen stretched to attain the correct contrast. A feature in maxim dl, which is called "digital development", then allowed me to bring out the background light. Similarly, I used a feature called "unsharp mask" to adjust the foreground light so that it was not too bright. Finally, I used "colour adjust" to bring out the red of the ionization band, while keeping the green colour of the nebula.
Eta Carina by Dylan O'Donnell

Dylan is the System Administrator from our ISP, Dragnet. This lovely image taken through the BVR filter set, was the first ever attempt of using an astronomical CCD camera by Dylan.  3 x 30 second exposures with Red, Green and Blue filters combined in Photoshop using channels. Levels adjusted slightly to balance histogram.
 

NGC1097 by Alex Shvonski

This image is a combination of 1 thirty second exposure using an h- alpha filter and 3 thirty second exposures with each of the coloured filters. Before the initial images were combined, they were deconvolved to create a sharper final image. Deconvolving is more effective in images that do not include nebulae because it seems as though the deconvolving process distorts the space around stars in the image (when these stars are in front of nebulae, nebulae appear distorted.) After the images were combined the final image was screen stretched to bring out the outer spiral arms of the galaxy. Because an h-alpha filter was used, some HII regions within the galaxy are visibly red.
