Subject: Mars again
It was clear last night for about the second time this month in Toronto due to a cold front
sweeping in with heavy gusts and turbulence. I'm still after my Mars shot of this opposition
so out I went. I'm not satisfied with this shot but it looks a lot more presentable after I hand
selected the best images to stack within AstroIIDC. Many of the images selected by the
software were not round but stretched as the wind buffeted the Tak OTA and stacking these
clearly diminished the detail. Despite the poor results I think that my collimation is getting
closer and closer especially after I managed to recenter the secondary mirror after it was
displaced during shipping. I can make out individual tendrils on the darker areas of the
surface.
I just need that one good night of seeing. I'm easily as grumpy as Alan about the weather!
