Hi Russ Is there a problem with attachements and Yahoo groups? I've never been able to see any of the pictures in any of your posts. Very fustrating. Cheers ...
Hi Frank, Dave, and Bruce (and Herb, Paul, Gary, Evert, and All), Thanks for a very helpful discussion on the “instrument” and science for the 22 meter...
Hi Wayne, Sorry about that! I'm not sure what's happening. I often (but not always) attache photos as well as placing them in the text. Perhaps when you ...
First Assembly of 1.5 Meter Telescope Once the planar trusses were cut out on the CNC mill, we couldn’t resist temporarily clamping the trusses together to...
Russ, I have only been scanning this thread but it seems to me that this 22m scope is not really even in the "visual light bucket" class. But it seems that it...
I had the same pictures problem, Slarty. Russ, do you have pictures of the cutting and clamping of those pieces? Will you share those photos? Bob Guzauskas ...
This is extremely impressive! You have found the right way to make the structure. The CNC machine makes a nice job! May I have just some questions and remarks:...
* Many thanks for your kind words and good questions, This is extremely impressive! You have found the right way to make the structure. The CNC machine makes...
* Hi Bob, I'm not sure what pictures you are referring to, but I'll attach a bunch of recent pictures. Thanks for asking. * Cheers, Russ I had the same...
Hi Russ, Excellent work. You are clearly making a big step in the development of this type of Alt-Az structure. When will you have the Appleply version? I'll...
Thank you very much for your extensive answer! Concerning OSB use, i should have read better your previous posts... Concerning the edge support, I meant the...
Hi Dave, Thanks for your kind words. The three students, Laura, Mounir, and Mike, are doing truly excellent work. The first report is in draft form and ...
Dave & Russ, thanks for the photos of your staff, the CNC router and miscellaneous. The photos raise other questions: 1) CNC routers, or router time, and...
Hi Bruce (and Dave and Herb), Thanks very much for your reply. So the 22 meter might be able to do some stellar intensity interferometry if the time...
Hi John (and All), Good point! You have consistently recommended steel as an appropriate material for telescopes (and have also consistently recommended...
HiRuss Let me introduce myself. I am an electromechanical engineer, 69 years old. I was born and I live in Mendoza, Argentina. I belong to GAMA (Mendocinos...
Hi Bruce (and David, Andrea, and All), Thanks very much for the references. I do have Brian Warner's book, High Speed Astronomical Photometry, and will...
Dear Pepe, Thanks very much for your email. Very nice that you are a sister group to the Rose City Astronomers. As you may know, we have a workshop toward ...
Good morning, * Hi Dave, I think the planar truss idea has a lot of potential for meter-class telescopes, and the OSB and Appleply prototypes are a good way to...
... I am working on my version of the solution every day. I have the 25" f/3.55 ( parabolic ) foamglass mirror ( weighing in at 19 pounds ) down to just under...
* Your suggestion that on the 1.5 meter telescope we use edge supports 45 degrees up from the bottom on each side of the mirror (90 degrees apart) is a good...
* Hi Bruce (and Herb, Dave, Andrea, and Paul), * Stellar Intensity Interferometry (SII) is certainly one of the more interesting applications for arrays of...
Hi Bruce (and Dave, Herb, Frank, Gary, Evert, Michele, and Paul), The next generation 22 meter system should have a smaller spot size (and may be available in...
Hi Gary (and Bruce, Frank, Evert, Dave, Andrea, David, Reed, and Joseph), Good chat on high speed photometry this morning. Good also on having a go at some of...
Hi Dave, Thanks. Good points. Bruce suggests arrays can be fixed spacing with electronic (digital) delays in the analysis. We may be able to effectively...
