The Newtonian spikes are created by the interference of light rays passing through the aperture of the telescope and the spike mask. The mask consists of a series of thin, parallel lines that focus the light into these lines. When the light then hits the camera lens, it creates a diffraction pattern that produces the spikes.

The spike mask is a simple and effective tool that can add a dramatic effect to images. It is a good choice for anyone who wants to have the Newtonian spikes in their astrophotography images without having to deal with image post-processing.

To use the spike mask, simply place the mask in front of the telescope objective and then move the telescope to a bright object, such as the moon or a star cluster. The spikes should then be visible.

Here are some tips for using the spike mask:

• Make sure the mask is clean before you use it. Dirt or dust can impair the image quality.
• Make sure that the mask is perfectly aligned. If the mask is not aligned, the spikes may be blurred or distorted.
• Use a telescope with a large aperture. The larger the aperture of the telescope, the more noticeable the spikes will be.

With a little practice, you can take beautiful pictures with Newtonian spikes using the spike mask.

• Attach the mask to the telescope and align it with the object to be photographed.
• Get the classic spikes of a Newtonian telescope in Live View.
• The spike becomes more clearly visible during the exposures.
