That's a great image of the Red planet,plenty of surface detail

Such a difficult planetary target

Well done !!


Looking at your set up -

130mm APO focal length 910mm
Focal length f7
2 x Barlow used

So you were imaging that night at f14

Camera pixel size 2.9uM


General rule of thumb for Planetary Imaging

Bad seeing 3.5 x pixel size ( focal ratio f10 )

Average seeing 5 x pixel size ( focal ratio f14.5 ) *****

Good seeing 7 x pixel size ( focal ratio f20 )


Any idea what the seeing was like ?
Was Mars bouncing around or fairly stable during your sampling ?
Just curious



Thanks



Martin
