Took this with a 254/1200 newtonian on eq6 in the night from 30th to 31st of october

Neptune c-II camera (imx 464)

2× barlow with backspacing for more magnification

Took 10 series of 3mins videos at 50fps

Stacked in autostackkert and derotated in LSW7

Final touches with gimp/astrosurface

I'm very happy with the result because mars is currently only 6.50" in diameter
