Get both versions of The Solar Observer’s Handbook: a signed softcover copy for your library, desk, observatory, or outreach table, plus the digital PDF for quick searching and convenient reference in the field.

The softcover is ideal for reading, browsing, and sharing at the telescope. The PDF is perfect when you want to quickly look up a solar feature, equipment topic, processing step, or observing concept on your computer, tablet, or phone.

Together, they give you the best of both formats: a beautiful physical book and a searchable digital reference.
