Was the corrector not set precisely this time? Red-blue halos!

The corrector managed to minimize dispersion on such a low Venus as much as possible, and I did not process the halos in Photoshop. Without it, it's much worse overall. Everything matches the visible image as closely as possible. I adjusted the corrector both visually and using the assistant in FC, and the effect is the same.

Well, that's a decent altitude! For such altitudes, the ADC really does its job!)) I shot at 23 degrees in May, I'll post the image now)

Posting as is, maybe I don't know how to set up the ADC.

I'm not nitpicking, I just want the shooting details! I also recently got a corrector from ZWO, so I'm looking at who, what, and how!)) Otherwise, it's a nice shot! Any frame is for yourself, it's history! A history of trials and errors. So let's keep shooting, experimenting, especially with the corrector!)) Need to get more filters that highlight Venus's clouds!)

I have filters for the infrared range as well as a ZWB2 + BG39 combination. However, I haven't been able to get any results that really satisfy me regarding Venus and its cloud cover. I've ordered a violet filter and will try again, but the phase is rapidly decreasing, even though the apparent size is increasing. We'll see. I posted it precisely for the record—whatever it may be, this is a real image. "As is."
