| This is the kind of trouble one gets into when there are only 4 clear nights in a month!
It has become popular to combine luminance data and color data taken from different sources. Tech pan is a popular luminance emulsion that is occasionally combined with other film color data or CCD color data. I thought I'd try something a little different. Since I haven't saved enough money to get my CFW for the new ST-2000, I thought I would try utilizing the ST-237 to grab color frames to apply to the luminance data of the ST-2000.
As a test of the concept, I took the color data from my best recent attempt at NGC891 with the ST-237 and, via Photoshop tinkering, combined it with the luminance data of the ST-2000. It took some stretching and registering, and I ended up only using the color data of the galaxy region itself since the rest of the star field would not align properly. As a final step, I reduced the original image size by 50% which conceals a good bit of processing.
The result below turned out much better than I thought it would. Of course not having the color data for the whole star field detracts significantly from the overal effect, but, it at least prods me to consider determining an optical arrangement that would closely match the FOV of the ST-237 with the FOV of the ST-2000. |
