ASI1294Pro color green screen
This is the second time that this happened. I shoot color binned 1x1 with an ASI1294. On the 0) tab I set my Bayer pattern, choose the algorithm (HA-OIII color, since I am using the Triad filter) and when integration is complete and I look at the integrated image the image is completely bright green. Not a green cast, completely saturated bright green. If I change the 0) tab to 'not supported' and uncheck the 'force Bayer CFA' the image is grayscale. This happened once before with another target taken with the ASI1294 camera. Any thoughts on what is the problem. I know that binned 1x1 so I did not destroy the color pattern.
This happens when you don't assign data to R, G and B. So, I always assign Ha to Red, OIII to green and blue.
edit: However, if you really chose Ha-OIII color (please double check) I think it should already do that...
I think you do need to "force CFA" as it's a color sensor but not identifying itself as such. And that is needed for the proper seperation of the channels. If you continue to have an issue, please send a few subs over for me to check the signal.. I'll give you server details if you indeed still have the problem.
So, I'm still having problems that I can't figure out. Here is an image that I processed
set to RGGB, Ha-OIII-color and forced CFA. as you can see it comes off as color. I did no further processing this is just the integrated frame. Here is data from the next night,
, the exact same settings. As you can see it is mostly B/W but if you look closely there are color artifacts that can be seen. Do you have any ideas about what I'm doing wrong? FYI, I also used the default "Adaptive Ariy Disk" and I get the first data set in color and the next night is still in B/W
Ok then, must be the data then I think. But to be sure, you can send the subs over to our APP server, login/password: appuser
Please create a new directory with your name on it.
Okay I just finsihed loading my files, I'm sure are you are correct it has somthing to do with my files. I wonder if it is a problem with my capture software and the ASI1294 camera. I use a bin of 3x3 for platesolving but 1x1 for image capture. I wonder if the images are being captured at somthing other than 1x1?
Shouldn't cause this issue no, if you upload some of the subs where you didn't have this problem and some where you do, I can probably get down to the cause. I'm downloading what you uploaded now.
Walter, I'm struggling too. Which capturing software are you using?
I use Prism Pro. I really don't know what I'm talking about 🙂 I was wondering if its an issue with the ZWO camera buffering first and then Prism downloading it? I really don't use PixInsight, but when I try to process the ASI1294 images I captured with Prism I get an error message something about improper geometry? That got me thinking that it was something about files are being mishandled.
Well, I'dont know either. But I think I got my problem solved last night. My images turned out monocrome after processing. Seems like if I tick of Force CFA check box I do get color after all. I use SGP btw for capturing.
Hope you get your problem solved soon. Best of luck.
Thanks for the suggestion but I have tried to that, checking the force CFA does nothing in this case
Hi! Just checking in with you. Do you have any new thoughts on what might be the problem that I having? Walter
No worries, problems need to be solved so that's fine. I did have a look, but I'm not getting color either. There however doesn't seem to be anything strange going on and I haven't heard about this from anyone else. My feeling is that it might have something to do with the processing just before you load them into APP, I can't think of anything else at the moment.
the problem with your hypothesis is that I did not do any pre-processing. These are right off the camera. As I said, it has happened before with other data sets taken with the ASI1294 camera. My hypothesis is that something is happening to the images when they are buffered by the ASI camera. FIY, Pixinsight does not like the images either. This is very disappointing.
