South Plains Astronomy Club

Observing Under The Dark West Texas Skies

On July 20, 2023, Tom Heisey gave a presentation on solar telescope and the solar features you can see with them. He recently purchased a double-stacked Lunt 60mm solar telescope and a Herschel solar wedge, so he gave a brief viewing session prior to the meeting. Fortunately, we had clear skies and an active Sun for the viewing session.

After moving inside, Tom gave a presentation based mostly on his research into the various solar telescope technologies used by the main manufacturers. The info helped him determine the manufacturer and telescope he eventually purchased.

Here is the presentation with added notes and corrections:

Tom has also started solar imaging over the last week or two and here are a few of his results:
