Posidonius

Hi,

Unlike my last posted crater image "Rhaeticus" Posidonius has been imaged many times


06/26/05, altitude 37 degrees, 18" Reflector, 9000mm FL, DMK-21F04 camera, 30fps, IR pass filter, stack of 763 frames from 2500, the low altitude would not allow a longer focal length.

Thanks,

Wes Higgins

Hi Wes,

A lovely image, and most interesting. I just spent a while comparing my best Barbados shot of that crater with your latest one. Both are at very similar illumination, so you can compare well. They look almost identical in resolution, and image scale...

This is interesting as it seems the seeing you had this night was the limit of what the 9.25" produced at Barbados under excellent seeing. I'd be interested to hear your comments on the seeing for that shot. It could go some way to provide more of an understanding at what level the big scopes leave the smaller ones behind on the Moon.

Best Wishes

Damian

Work of art again Wes, very smooth processed
