Explanation
by the owner
I remade the telescope making kit (
KT 10 cm ) from Orbys . I ordered the mirror to change the original f=500mm
mirror to more longer type of f=900mm .So I cut the tube and made it longer
with stainless tube
As this telescope is specialized for the moon and planets , I set the outer focus long enough to avoid the reflecting light and attached the black pile tape inside of the the tube . So the contrast of the image is rather good although using the open tube .
I can feel light ass image .
The following picture indicates the surface
of the mirror on this telescope. It seems not so good.
