How to make a solar finder for your telescope. Comment faire un viseur solaire pour votre telescope.

A very cheap but effective way to locate the position of the Sun when observing it through a telescope fitted with a solar filter. This replaces the spotterscope and has the added advantage in preventing injury due to leaving the spotterscope in place whilst solar observing. Instructions are also available on this channel for the making of a sturdy solar filter using BAADER planetarium solar film. Thanks to  jdsgotninelives  for asking the question on my filter film, which prompted me to show how I made the solar finder.

Une manière très efficace et pas chère de localiser la position du Soleil en l'observant à travers un télescope équipé d'un filtre solaire. Cela remplace la lunette de visée et présente l'avantage supplémentaire dans la prévention des blessures en raison d'avoir laissé la lunette de visée en place. Des instructions sont également disponibles sur ce canal pour la fabrication d'un filtre solaire robuste avec le film BAADER  astrosolar
