Thank you, Matt. -- Joe ________________________________ From: "Hutchings, Mat (H USA)" <mat.hutchings@siemens.com> To: Utah Astronomy <utah-astronomy@mailman.xmission.com> Sent: Wednesday, July 13, 2011 4:49 PM Subject: Re: [Utah-astronomy] ATM session report and next month's planneddate/time Joe; I will absolutely send out a reminder a week or so before the next session. As far as telling you what to bring, see my message from a few days ago: I have soldering irons and plenty of solder, but you should bring all other supplies (resistors, wire, etc.) you may need. The following link that Jay previously sent is a very good resource: http://www.dewbuster.com/heaters/heaters.html This site should tell you what value resistors you will need to obtain. You should be able to get the resistors from Radio Shack, or any other electronics parts house. I'm sorry I cannot give you more details than that, this is because I don't know what physical size dew zapper you need, or how many individual zappers (objective, eyepiece, finder, etc.) you want. If the website does not help you, let me know and we'll figure it out together.

I want to work on a dew zapper.

With their help, that mirror progressed through 320 grit, then 500, on to 12 micron and then just after the session, I finished up with 5 micron. It is now ready to be polished. Those of you who have made mirrors, know that now, the real work begins! I may keep this mirror like it is for now and work it only during the ATM sessions, so that attendees who have not worked a mirror can try it out. Any of you who are curious about making mirrors, don't be shy about working this one with me. Short of dropping the thing on the concrete, there is virtually nothing that you can do that will permanently harm the project. Next session there will likely be people working on dew zappers and I will continuing work on the 8". As usual, any other projects that any of you might want to bring and work on are welcome. The next session will be on August 13th from 9:00 to noon. I can easily go longer if any of you want to keep working your projects.
