 Telescope Filters Guide: Planetary Filters

An important role plays the filters for observations Planets and objects in Deep Space. You might argue about filtering of light – you gave a lot of money for large aperture exactly to gather more light. But in Astronomy not every light is helpful.

Certain wavelengths of light coming from, for example, a nebula, do not contribute to detail. If you remove them, the image that remains is much sharper and have better contrast.

Telescope filters do just that: eliminate light that does not add any detail to the object. What remains is a much cleaner image, that lets you see the finer details with better contrast.

Different objects require different types of filter to see them best.  Jupiter’s Great Red Spot needs a different filter than this for polar regions of Mars or Venus’s clouds. In the chart below you can find the appropriate filters for the various objects and the top 5 Planetary Filter Sets on the market today.

Solar Filters for Telescopes

If you are looking to buy a solar filter for your telescope, then let me tell you that it is almost impossible to find the right one for you. The reason is that unlike other filters, solar one does not apply into a standard 1.25 inch eyepiece, but should be put front of the tube, where all light gets in. Now days there is countless types of telescopes in the market with different sizes and solar filter should fit perfectly on your telescope.

Something very important !!!! Never Ever point your telescope to the Sun without sun filter and never look through the eyepiece. You risk losing your eyesight, and damage the telescope.

So, after it became clear that it is difficult to find a ready solar filter for your telescope model, the next thing you can do is to create one. Idid it, and that means everybody can do it too!

If you are from those who are not very handy, it means we are much alike. I’m not that “always creating something” person, but my desire to look at the Sun was so big that I couldn’t resist.

For my big surprise making a Sun filter  was not only easy but also very enjoyable work.

After a thorough study on youtube videos I chose the one that most clearly and accurately explain what is needed and what should be done. There it is:

 What you need is:

• Solar Filter Sheet for Telescopes
• Pensil 
• Cardboard
• Scissors
• Scotch tape
• Enthusiasm

The solar sheet can be ordered by the review further down in this page. For my 6 inch telescope, 10 inch square perfectly matched the filter which I made.

Follow the steps in the video and you will succeed. Here are some pictures from my personal experience with the preparation of the filter. And the prize? Well, you will have to look at the Sun with the telescope.
