MAS Observing

The Yanna Research Station (YRS) has been the Madison Astronomical Society's prime dark sky site since 1984. It is available for use by members and their accompanied guests.

Named for LeRoy Yanna, who donated the land, the Yanna Research Station is home to the society's four permanently mounted telescopes (2 dome and 2 roll-off buildings), a heated and air-conditioned clubhouse, a sanitary facility, and 7 concrete pads with nearby electrical access where members can set up their own observing equipment.

Located approximately 20 miles south of Madison, the Yanna Research Station skies are dark enough to support a variety of observational and photographic activities, as well as simple enjoyment of the nighttime sky. Observing members can access all the telescopes and equipment after a brief training orientation. Other members can make use of the site for its dark sky qualities.

If you are interested in becoming an observing member, or in learning more about the Yanna Research Station facilities, please contact the observatory director.

Photo Gallery

Don't miss the MAS Astrophotography Gallery.

MAS members are invited to submit their best astronomical photos to the Gallery. As many as possible will be posted.

Some guidelines:

Keep image file sizes moderate. About 300 Kb is fairly large. 50 Kb or 100 Kb is better. We are limited to about 10 Mb of disk space for our website. So bigger images = fewer images. Maybe images will have to be replaced from time to time.

Give the image file an informative name:

is better than

Provide a thumbnail.

Give the thumbnail a name derived from the name of the main image file, such as:


Thumbnails should be about 3 Kb to 5 Kb and 1 in x 1 in, up to 2 in x 2 in, and roughly the same shape as the larger image. If the main image is 4 x 6 in, then the thumbnail could be 1 in x 1.5 in.

Keep in mind that large thumbnails slow down the loading of the images page, since all the thumbnails on the page must be downloaded. If you have a broadband connection, remember everyone else who doesn't.

Provide a description of the image, such as:

Planetary nebula in Lyra
Globular cluster in Hercules
Region of the Milky Way in Saggitarius
Note the extensive dust lanes in this ...

The most useful (read least work for the webmaster) way to provide information about an image is to fill in the following HTML template, which can then be pasted directly into the photo page. Leave the HTML tags alone; just change the information as appropriate. If there is no info for a given tag, erase what is there and leave it blank.

(Work is progressing slowly on a forms-based submission mechanism.)

Copy the template, paste it into a new email message, fill in your information, attach one main image and one thumbnail, and email it to

(Leading spaces are part of the template.)
