Two images of Mars taken 1 hour apart. First image taken during daylight while sun was still up at 7:20pm, next image taken an hour later at 8:20 pm. You can see the rotation - approximately 15 degrees, similar to Earth's rotation.

10" Mak-Cass, QHY-5II camera.

Excellent stray-light control in your 10-inch Mak-Cass to get excellent contrast even with Sun light blue sky producing optical noise for imaging Mars.

Technically and aesthetically excellent image-!
