Sun Test

Below is an image of the Sun from a test run using the Mallincam SkyRaider on a Coronado PST. Even though this scope is not specifically designed for photography, it worked well with the SkyRaider.

I don't know what is causing the banding across the image, though...

I found out that the bands in the image are called Newton's rings, which are caused by interference patterns in monochromatic light. They are very common in narrow band imaging with these types of cameras. If I have time tomorrow I will experiment with some techniques I read about to eliminate or reduce them.

Here is a close-up (slightly enlarged) of AR 2671, the sunspot region visible near the center.
