Double images on handmade Dobsonian telescope?
My husband and I are just finishing up our 6" scope. Images are clear, but we are seeing double. Anyone know what the problem could be? Here's the specs:
6" F8
Focal length = 48"
1.5" secondary
Collimation seems good.
Thanks!
We purchased the mirrors from Hands On Optics. Primary has 1/6 peak to valley wave. Secondary has 1/10. Didn't do Faulcult test. Eyepiece is a 25mm taken from a 3" Bushnell scope that functioned fine.
If the collimation is good, check the mounting of the mirrors. Both mirrors should float in their mountings. A tight clamp or other restrictive mounting can distort the mirror and cause a variety of problems. Geoff's suggestion is a good one, too - find someone who knows telescopes to look it over.
