Description

This time I used the 1mm distance ring to fine adjust the distance between sensor and corrector.

1mm seems to be too much distance between DSLR sensor and coma corrector... the borders are worser than with the 0.5mm ring.

And still not enough focal length for M 57 Ring Nebula, one of my favorite objects... but far better than with 400mm :-)

Drizzled 2x
