Comet Leonard C/2021 A1 visiting Southern Hemosphere
As soon as the comet began to move away from the Sun, its visibility season in the southern hemisphere began. Comet was near the Venus today.
During the shooting, I also observed visually with 50x10 binoculars. Core & come is clearly visible like a fuzzy star about 4.4m, tail was barely visible on the light sky as very short & wide rabbit's tail close to the core.
Image was taken in the twilight when comet was 20°-10° above the horizon.
Total 64 frames all with 30 sec exposures at Gain 100. 12 Red, 11 Green, 11 Blue, 34 Light taken in [LRLGLB...] sequence
Version 1 - Weighted sigma-clipping stacking removed all stars. White balance by the core.
Version 2 - Weighted sum stacking without sigma. White balance naturel for zwo filters. Yellow color may be defined by the Earth's atmosphere at object's low alt.

Hardware:
Tal-250K with F/6 reducer MkII, ASI2600MM camera with ZWO filters, EQ6PRO mount. Balcony in Brisbane.
Nice, thanks.
The first version in particular conforms neatly to what I’ve been able to see, but of course you imagers get more light and detail, so thanks for sharing.

Terrific capture Igor. I was straight outside with my binoculars. Took around 1 minutes to find it just a green blob. I will be out tomorrow night weather permitting trying to capture my first comet. Can't wait till its higher in the sky
