🔍White light filters show the photosphere and features like sunspots and granules.
🌞Hydrogen alpha filters reveal the chromosphere and features like prominences and active regions.
✨Calcium K filters provide detailed views of the chromosphere, including sunspots and the chromospheric network.
What is the purpose of using solar filters?
—Solar filters allow safe observation and imaging of the sun by reducing the sunlight and harmful UV and infrared radiation.
Which filter is best for observing sunspots?
—White light filters are commonly used to observe sunspots. They reduce sunlight and reveal the photosphere where sunspots are visible.
Can I use a regular telescope for solar astronomy?
—Yes, you can use a regular telescope for solar astronomy by attaching the appropriate solar filter to the front or back of the telescope for safe observation of the sun.
What are some of the features visible through hydrogen alpha filters?
—Hydrogen alpha filters allow observation of the chromosphere and features like prominences, active regions, and the chromospheric network.
Why is a monochrome camera recommended for solar imaging?
—Monochrome cameras are recommended for solar imaging because they provide better detail and sensitivity to the narrow bandpasses of filters like hydrogen alpha and calcium K.
