Hey Doug,
That’s something I haven’t heard of before so quite keen to understand and try it out. So if I understand correctly, you would:
- Position the star in the center of the fov
- Out focus the star until the central obstruction just appears
- Move the scope in the direction where the star focuses properly
- Use collimation screws to move it back to center
Is that right?
I assume that requires a tracking mount, is that right? If so, I might try it out next time I collimate my C5.
