Eclipse preparation workshop: How to safely view and photograph the sun

March 9 @ 11:00 pm - March 10 @ 3:00 am

This event is for people who plan to observe or photograph the upcoming April 8, 2024, Solar Eclipse (or do any solar viewing or photography).  For more information and to register click here.

In order to safely participate in this event, you must have solar filters or Baader film that is appropriate for your camera or telescope unless your equipment has a built-in solar filter, such as a Coronado PST.

If you do not already have these filters or materials, we recommend that you visit Mile High Astronomy at 9797 W Colfax Avenue in Lakewood or purchase your equipment online soon. B&H Photography in New York City also has simple Baader filter sheets for do-it-yourselfers and pre-made Baader filters for various telescope diameters. With the upcoming eclipse, stock may be low. Don’t wait!

Workshop Objectives:
 Learn how to set up and safely focus either cameras or telescopes at the Sun under midday conditions.
*  Observe and photograph sunspots and the coronal discharges of the solar chromosphere.
* Fine-tune your personal camera settings (ISO, aperture, exposure times) for solar imaging.
*  Plan a solar eclipse shooting session involving progressive darkening, almost total darkness, progressive lightening.

Camera Gear: DSLR with 300-400mm focal lens, or telescope with T-ring camera mount.

If folks want to connect their DSLR cameras to a laptop I suggest:

  • they download free “Digital Camera Control” from Source Forge,
  • they bring a suitably long USB cable,
  • and a box sufficient to shade their laptops from the outdoor sunlight.

WARNING!: Looking directly into the sun with a telescope will lead to permanent blindness.
