Weird Anomoly

TimPilot
in General
I have a weird anomaly in the lower left hand corner of this integrated image. I have blinked through the Lights, Dark's, Flats, and Bias frames and see nothing that would account for this. I am pretty stumped as to where it came from. I have run WBPP three times and it is always there. Thoughts?

    If you did not run DBE or anything like that.. and you see this in your master light (simply integrated image)... then the issue is likely to do with your calibration files. If you have a light leak in your darks this would cause it. If you have a mismatch between your flats and lights, this would also cause this issue. There are also a few other wilder things too... 

    So I guess you follow the approach I lay out in FastTrack Training. You need to look at all of your raw calibration files and all of your raw lights. Then you look at all of your calibrated data... does every file show this? Only some? What is the degree of darkness there in numbers compared to the sky values? Questions and questions...

    I did do that, checked all my flats, and darks, even looked at the bias files, as I said it is weird. I checked my integrated flats and darks and did not see the blob, but did see it in the reference frame, so it has to be in the lights somewhere. Re-blinked very slowly and removed a few questionable frames but did not see the blob anywhere. I may re-run WBPP and again and see if I get anything different. On the other hand NoiseXT has done wonders for this light polluted image background.

    Something you might be able to help with. I am using a three monitor setup and am clueless about how best to do this. I am viewing PI on my left monitor and when I click to look at the numbers the window with that information doesn't appear near my cursor, but on the center monitor, haven't found that setting yet.

    Re-Ran everything, the blob is still there, I will just have to crop it out. It is obviously in the light frame but I cannot see it.

    PixInsight is not designed to be used with multiple monitors. Typically there are some graphic hiccups (depends on the hardware/drivers). As long as you understand you may experience some display issues- it is not big deal- but I would not try to fight the "it should work" mindset with multiple monitors.
