My first Scope and Problem!

[PlanilAstro]

Hi all
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.

Hi,

Welcome to the wonderful world of Newton rings! The bands are an interference pattern produced by internal reflections, often off the camera glass. You will really only see this when imaging narrowband like Ha. I have them very pronounced with Barlows, especially with the ASI1600MM. The most commonly used solution is to tilt the camera slightly. I like the Daystar Interference Eliminator, ZWO also makes one, and there are any number of do-it-yourself solutions.

Cheers,

Patrick

Hi there, the lines are newton rings, it is a common problem with some easy fix's, you could try tilting the camera (my preferred method) or take flats, below is link to an excellent article for solar imaging.

Thank you very much for answers from FlankerOneTwo and Brendan

The solution is to tilt the camera slightly. Need an accessory? If there is a link to explain it. Please tell me
I started shooting the sun for the first time. If there is anything I should know. Please tell me.
I will try again.

This is the one I use. Easy to adjust on the fly.

I had one of those first, however not quite as easy to adjust when the camera (ASI1600) is mounted. I think the Daystar has more tilt as well - the 1600 needs a lot :-/

It worked fine for the QHY5III 174, though.

I had this scope and the filtering unit clouded over so Daystar replaced it.You May want to check this as well.
