Equipment:
-telescope Celestron NexStar 8 SE
-Barlow lens cell NPZ 2x
-atmospheric dispersion corrector ZWO ADC
-camera ZWO 183MC (green channel from previous image) + filter ZWO IR-cut
-camera QHY5III178m + Antlia CaK 3nm 393.3nm.
Stacking of 1000 frames, wavelets in Registax 6.
False colors: G, G + UV (50%), UV.

The Antlia CaK filter proved to be suitable for capturing the cloud cover of Venus. True, the brightness of the image turned out to be noticeably less than that of a stack of ZWB2 + SZS filters, so I had to increase the camera gain when capturing.
