I am PlanilAstro, a new user for Solar Image. I buy Used SolaREDi60 0.5A Solar Telescope from OPT web. It's beautiful when viewed through the Eyepiece lens. But when I applied to CCD to take pictures. It appears to be a pattern similar to noise.

Image 1 : When the focus is on thin lines. Looks like noise.

Image 2 : When not focus I see the problem show.
I use SolaREDi60 0.5A Scope and ASI290MM CCD , no other filter
Thanks for helping me solve the problem.
