[2001-Apr-10] If you're considering grinding your own mirror, and you should be, you'll need to know what materials and tools needed to get started. Click here to read Ken Slater's, of the Springfield Telescope Makers, article on how to get started collecting the materials you'll need.
[2001-Mar-30] On March 20, the third in a series of astronomy related classes was held at the Springfield, VT middle school.

[2001-Mar-1] If you're planning on grinding a mirror (which you should be) you either may not have a second glass mirror blank or may not want the extra expense of a second glass blank, especially if you're grinding a large mirror, to use as a tool. The solution is to make a plaster tool as a substitute. Click here to read Ken Slater's, of the Springfield Telescope Makers, article on how to make a plaster tool.
[2001-Mar-1] After you make your tile tool, you'll need to attach tiles to the surface which will do the actual grinding. Tiles have the advantage of many more cutting edges than a plain glass blank which makes the grinding process go much faster. And, once you finish the mirror you can replace the tiles and use the tool again on your next mirror! Click here to read Ken Slater's, of the Springfield Telescope Makers, article on how to make a tile tool.
[2001-Mar-1] Once you have finished the rough and fine grinding process, you'll have to polish your mirror to a very smooth surface and figure it's shape to focus the star-light correctly. For that you'll need a pitch-lap. Click here to read Ken Slater's, of the Springfield Telescope Makers, article on how to pour a pitch-lap.
[2001-Mar-9] Now that you have you pitch-lap ready to go, you will want to learn how to keep it in tip-top shape. Click here to read Ken Slater's, of the Springfield Telescope Makers, article on how to maintain your pitch-lap.
[2001-Mar-1] Putting on the annual Stellafane Convention is a huge undertaking, that requires the help of many individuals. As I have discovered, so is putting out the Stellafane Newsgram. It was my intention to have the Newsgram ready to go to the printer by the middle of November, but, due to my work schedule and the schedules of others involved with the production of this publication, we were not able to meet our preset deadlines. It's the old situation where life gets in the way. As the editor, I apologize to all who have made a donation to receive the Newsgram. On a note for the future of the Newsgram, I intend to make an earlier deadline for the 2001 edition, hopefully getting the Newsgram into your mailboxes by late October or early November. I'm sure that with increased efforts we can achieve that goal. I look forward to your continued readership.

[2001-Feb-27] On February 15, the second in a series of astronomy related classes was held at the Springfield, VT middle school. During this session, Junie Esslinger and Bead Vietje of the Springfield Telescope Makers taught the students basic optics and constructed simple telescopes so the students could get a feel for how telescopes work.
[2001-Feb-2] On January 30th, the first in a series of astronomy related classes was held at the Springfield, VT middle school. During the first session, Junie Esslinger and John Martin of the Springfield Telescope Makers familiarized the students with Stellafane history from the early days when Russell Porter began his first mirror making class in the local machine shops up to the current days of the conventions. Subjects that will be included in upcoming classes are basic optics, mirror making and astronomy with the web. More to follow!
[2001-Jan-24] The bulletin and registration materials for the 2001 Stellafane convention are in the works. If you have any suggestions about the information that is included in the convention mailing please let us know. Thanks!
If you'd like to get information about this summer's Stellafane convention now go to the convention information page.
[2001-Apr-16] Please note: The optical judging during the Stellafane convention has been scheduled for the Friday night of the convention at 10pm! There will be no optical judging Saturday night unless Friday is completely clouded out or early clouds force a suspension of judging that has already started! This change has been made because it provides an additional night for optical judging. We will have a better chance of holding the optical judging if there are two nights instead of just one. Please pass this information on to anyone you think may need to know! If you have questions or comments regarding this schedule change please let us know. Thanks! The STMs.
