You can choose the H-alpha image mode that best suits your needs: Chromosphere for details of the solar disk, or Prominence to highlight solar prominences. To have both modes in the same instrument, check out the <a href=\"https:\/\/deep-space-astronomy.ch\/en\/product\/daystar-quark-gemini-combo-deux-en-un-pour-sct-et-mak-chromosphere-et-prominence\/\">Gemini Combo<\/a>.<\/p>\n<p>The setup depends on the diameter, focal ratio, and design of your instrument. Without a built-in telecentric lens, the Combo may require a suitable telecentric Barlow lens and calls for appropriate energy-rejection filters.
