Luckily, it warmed up slightly on Jan. 26 for our ATM session! Charlie, Chuck, Jay, Jeff and Josh all attended and made it a great session. No mirror work went on, probably because it was too cold to do any serious work with our hands. Charlie and I discussed a good method for using his grinding machine for his project. Chuck brought by a very cool 6" grinding tool that is a composite of ceramic and, I believe, polyester. I am looking forward to trying it out on an upcoming mirror. Very glad that Chuck attended and am hoping that he is able to make it again in the future, as he brings a wealth of ATM experience to the table. Jay shared ideas and plans he has for a nice wooden eyepiece case. Jeff made some collimation tweaks to his 12" Orion dob. I believe the views will be impressive through that telescope after the changes he made. In preparation for hosting some telescope making friends from California, Josh and I discussed some refinements to his bath interferometer. Those refinements will make getting repeatable images of fringes (igrams) more obtainable. I shared the dew heater and controller I recently built. It works very well and is a necessary accessory for cold, damp nights. Since the ATM session, I have completed a version using a printed circuit board I made, rather than perf-board. That version is much more durable. I am willing to share the plans and assist anyone who wants to build one. To make one is considerably cheaper than what you can buy. We were treated to a great lunch of "white chicken chili" made by my wife; it was awesome! The next session is on 2/23 and then another on 3/30. Sometime after that, we will likely be having a Friday evening and Saturday session again; stay posted! Mat This message and any attachments are solely for the use of intended recipients.
