Imaging the International Space Station Settings: f/6.3 1/1600 600 mm ISO 400 Should work everytime.

Theoretical vs Achieved Resolution with SCTs 5 inch SCT

Double stars are good targets for testing the resolving power of a telescope. Here is epsilon bootis.

The theoretical resolution of a 5 inch telescope is between 0.93 and 1.10 arcseconds (Dawes and Rayleigh limit). So what

Attempt to see if WinJuPos does anything It’s not easy to tell if WinJuPos de-rotation help in a detectable way.

Since I have a 5i I might as well see how well I can get it auto-guiding. I have used

I rearranged the imaging chain on the 5i. Basically I took out the Atmospheric Distortion Corrector. So now it is

The attempt was to fine tune the pixel size for the ZWO ASI120MC. The pre-calculated values are shown in this
