Vince: Have you tried operating the camera with your laptop and NINA for example, in order to compare the results? It is possible that your issue, is a flat correction one and not the driver's fault. |

| Screenshot 2022-12-26 233106.pngHello, the issues I'm having persist, it's all very frustrating. Here is an example of 4 images with ~1 hour data (5 min exposures) from 533mc pro with uv/ir cut filter and with a variation of calibration files applied. I used DeepSkyStacker for these, with the same settings. The only processing was an Automatic background extraction. All calibration files are same temp as lights (-10C). Dark are also 5 min, same as lights. Flats were 1 second, getting adu to suggested amount. Flat darks were about 1 second as well. Top left: just lights, no calibration Top middle: lights with darks Top right: lights, darks, and flats Bottom right: lights, darks, flats and flat darks  I went ahead and didnt do the ABE. Instead, just did a linear fit to adjust for green. Left: lights with dark, flats and dark flats Right: lights only. You can see how much worse the photo gets with the calibration files (probably just the flats and dark flats). You can see a bit of the green/red pattern on the lights image on the right, but the calibration files just make it worse!  |

More proof that it's the red channel.. It just does not make sense to me that ZWO software and Cameras working together would produce this type of issue and have it be a driver issue or something of that nature... From left to right, G, B and R on the right. You can clearly see issues with the red channel. The G and B channels have more of a classic color gradient probably due to light pollution.  |

Vince: Hello Vince, Indeed it makes no sense at all and frustrated me enough to almost get rid of the camera,but for my case the issue was the driver, both with NINA and SGP, ZWO drivers produced a similar effect with what you are posting. So it is worth trying to shoot in one session with both drivers on a bright object (M45 is fine) and compare the subframes AFTER calibration. I had exactly the same issues with you,hope that this will be your issue! |
