Quote:if you are doing it manually you can do whatever you want, CFA or RGB. both formats are raw formats.
the only way BPP can be told that an input file is from a OSC camera is by checking the "cfa" box. otherwise it assumes that the files are from a mono camera.
when "cfa" is ticked, the batchpreprocessing script passes the format hint "raw cfa" to the DSLR_RAW module, which overrides whatever is set in the DSLR_RAW module (the screenshot you show above.)
attached is the tooltip for the "CFA images" checkbox.
Quote:I think you're too conservative by one step. it's okay to let BPP do the alignment (registration) of images. it's even okay to let BPP integrate the image, but that integration should be considered as a preview. as i mentioned this is because you'll probably have to iterate a few times setting the pixel rejection sliders and looking at the rejection maps to make sure you got the rejection parameters right. you want to reject as few pixels as possible (just hot pixels, cold pixels, satellite trails, airplanes) and not any real DSO data.
Quote:By the way with OSC cameras the task of calibration is somewhat straightforward - you usually have a single master flat. so it's not terribly difficult to do everything manually. but that still means setting up ImageCalibration, executing it, then running the batchdebayer script, then setting up StarAlignment, running it, and finally loading up ImageIntegration and running it.
if you imagine that you're using a mono camera with filters, the calibration task became that much more of a hassle… say you did L Ha RGB on some target… now you have to manage 5 flats and 5 runs of ImageCalibration, plus all the rest of the stuff above.
that's why BPP was developed in the first place; it tries to automatically match up flats with lights, and also choose the right dark for the particular frame being calibrated. in theory you should just be able to throw everything in there and let it rip. in practice i don't know, because i still do it the old-fashioned way
Quote:At any rate 'raw CFA' and 'raw RGB' are entirely equivalent, it's just a matter of how the raw data is represented. the CFA file is smaller because the CFA file is one plane (mono) and the RGB is 3-plane. there's a bunch of wasted space in the raw RGB file - black pixels. so for the sake of disk space the CFA files are a little better.
the Debayer module (and by extension the BatchDebayer script) knows how to handle raw RGB or raw CFA files.

Quote:but i think step 2 depends on the acquisition time being in the FITS header and not sure if CR2 metadata makes it into the FITS header…
Quote:5) create a star mask; with star mask applied to comet-aligned image, copy stars to comet aligned image with pixel math.
Quote:then if you put the name of the comet-aligned image into pixel math (the RGB/K field), turn off rescaling, and then apply the pixel math expression to the masked image, the stars should get copied over.
Quote:On a side note, I am not so sure about what you said earlier, "use the CometAlign process to re-align the star registered images to the comet"; I have done that and I don't see any difference between ImageIntegration result of StarAlignment and CometAlignment processes [i.e., before doing any masking or pixle math-ing, etc.] I am not questioning the logic of what your are saying, but I am questioning the results I am getting which look no different whether I star align or comet align. This is the reason I say we trace our steps all the way back and start from scratch. Regards
Quote:Comet Alignment is not an automatic process. You have to click on the location of the comet in the first and last images, or enter the X,Y coordinates manually (or enter the dX,dY values manually). After you have added the files, under the parameters section, click the first 'show' button. The first image will appear. Click on the location of the comet (there will be a green circle around where you clicked). Then do this again for the other 'show' button (for the last image).
I lost count of my scopes. Now I just want mobility. I came, I saw, I bought some interesting accessories, and put names to faces: NEAF 2012, ASAE 2012, SWAP 2013, ASAE 2013.
