| Process 2 ResultsM13 - Globular Cluster: This is a wow image - process 2 seems to work very nicely. Notice the full corkscrew pattern of the bad spots. This image should be flipped. There still seems to be a bit of smear, but that could be an exposure time issue. Alignment and tracking should also be investigated to determine how well the Meade tracking really is. M13 Reference Image: M81: The image above is of M81 data already shown on a process 1 drizzle. Much more definition of the spirals of M81 are visible in this Process 2 drizzled image. Image was not flipped. The above image is the same, but has been colorized to bring out the intensity variations. It also shows the CYMG pattern in the bad spot streaks. This effect of CYMG was not recognizable in process 1, but stands out nicely in this colorized version. I had not noticed this pattern previously. Image was not flipped. This is a drizzle of the CYMG image converted to luminosity images using the Meade software. The luminosity images were then drizzled to get the above result. Quite impressive. Notice the black dot in the center of the star at the bottom left of center. This black spot is not in the CYMG images, but was in the luminosity and RGB separated images. This may be due to representing integers incorrectly in some of my earlier software or may be caused by Meade's software. This should be researched. The above is the same data, but each of the CYMG images was broken into it's RGB components. Each were individually offset using the data from the luminosity RegiStax run and then individually drizzled with Meade's software. I then used the FITS Liberator (NASA Goddard Space Flight Center) to import the Red, Green and Blue components. M81 Reference Image - the image is rotated to almost exactly the same orientation as my images above (the flipped images). This image shows that the colorized version of M81 from the DSI appears to be showing the same colors as the actual object. Color processing of images appears to be quite attainable. Enhancements show more detail: Same image as above with enhancement to show the spirals of M81. Enhancement affects the object just as much as the bad spots. Notice in this image that some of the larger stars have a blue side and a red side. This is due to the variations in the drizzle function of the separate colors. The base rotation amount is not identical for all three colors, thus providing this color streaking. A more sophisticated color drizzle function is required. Meade does it on the fly, but I was not able to figure out how to post process in color. M81 Reference Image - additionally enhanced by me in a similar fashion as my enhancement above: M104: The same method used with M81 was used with M104. Very nice results. Bad spot and dark processing will need refining as I move forward. Notice the Red, Green and Blue components are smeared more than the M81 image. M104 Reference Image: Notice that my M104 image color does not appear to be similar to the M104 reference image, but it is not as red as my M81 color image. |
