Hi all,
Below is my first image with the GSO 8" f/4 scope that I recently acquired. M42 was my
first light with the f/5, so I thought it was only appropriate for it to be the first light of this one too - except that this time, I have a wider FOV and a larger sensor, meaning I was able get Running Man in the frame too.
On a technical note, collimation is a real challenge to say the least. I lost collimation after a simple meridian flip and will need to scratch my head to get good collimation in the first place, and then not to lose it when slewing. A friend suggested foam strips between the primary mirror and mirror holding clips.
I am also aware that there is quite a bit of star flaring. I might mask the the clips on the primary mirror with a design similar to
this one.
Otherwise, hope you enjoy looking. Feel free to comment.
Bigger version here.
Clear skies,
Stéphane
