I finally had one clear night I was able to get the telescope out and attempt to do some LRGB imaging with my new ZWO camera. I picked the Whirlpool Galaxy as a target and did (as a test) five 120s images on LRGB filters. The individual frames turned out pretty good and I figured I'd get at least a somewhat modest image in the end (for the short duration of exposure). This is where I hit an issue. Processing the LRGB files.
I used Pixinsight and the Batched Preprocessing script like I've done on other images in the past (from the DSLR). I had prefixed the individual files so that Pixinsight recognized the individual filter files and in the Light Files section of the script it had the individual channels separated correctly. This raised the big question though: do I WANT to do ALL the channels at once?
I ask because in the end, after the files were run through BPP, I opened the Master files at the end and used the LRGBCombination tool, with everyone set at 1 for weights. The end result? I got what (for practical purposes) was a B&W image. The individual channels (for RGB) were all perfectly aligned and seemed equally intense. So I had really no color to the image. Do I need to process each channel through BPP separately (with the same reference file)? Or did I just have crappy luck? Or even yet, something further I need to do to the individual channels before combining them in the Combination Tool?
Scouring some tutorials this morning (while at work) to see if I can find something, but nothing so far is leaping out yet, so thought I'd ask. Did some searches on the forum here too but nothing specific to an "all white image" or anything similar. Heh.
