1. Remote Observing at the Dark Ridge Observatory And Beyond… Thomas C. Smith, Director, Dark Ridge Observatory SAS 2008, Big Bear, California

2. A Statement of Fact Students that utilize remote observatories to conduct their scientific research are often at the mercy and whims of the observatory owner/operator

3. What is the Problem In today’s growing arsenal of remote observatories, many have provided the use of their equipment for both research and astrophotography but for most remote sites the support ends there

4. So What’s Different At the Dark Ridge Observatory students are made a part of the entire observatory and observing process including data reduction, analysis and incorporation into scientific papers in both refereed and non-refereed scientific journals

5. A Bit More Detail At the Dark Ridge Observatory the student is guided through the nuances of the host equipment to achieve scientific accuracy for their measurements At the Dark Ridge Observatory the student is guided through the nuances of the host equipment to achieve scientific accuracy for their measurements This process provides mentoring for the student in areas of data collection, reduction and understanding of the use of astronomical images in science This process provides mentoring for the student in areas of data collection, reduction and understanding of the use of astronomical images in science

13. A Typical Collaboration During the start of a student collaboration there are many things that need attending to before the actual images are taken During the start of a student collaboration there are many things that need attending to before the actual images are taken Here is one such example conversation that took place via email: Here is one such example conversation that took place via email: Jo, I managed to get the computer for the 14” fixed and imaged all four of the M stars tonight. I’ll put it together in an Excel spreadsheet like the previous ones but only after I get the paper parts that I owe you together first. Here is a teaser “RAW” image for you of STF 126AB. Thomas C. Smith Dark Ridge Observatory Hi Tom, attached are what I think are the components. for whatever reason, GRB 34AB is not centered. STF 72 has an incredibly sparse field very similar to 3 Peg. STF 126AB has several possible secondary stars. however, I believe the brightest one is the secondary because it is comparable to other tenth magnitude stars on Aladin. Jo Hi Jo, The declinations of all the stars are well placed for decent observations. Most are quite bright however but this should not make it too difficult to image them. Right now I am in the middle of a horrific wind storm with gusts over 80 miles an hours. It has also been raining here and cloudy when not raining so I have done no imaging beyond what I did a week ago. If the weather patter holds to the predictions it should be really nice for the next three days/nights so maybe I can get a chance to image these systems. Have you looked at them on Aladin to see if you can identify the components? I'll let you know what I find. Thomas C. Smith Dark Ridge Observatory Hi Tom, I have done a little bit of 'data mining' in the WDS Catalog and have found a few interesting M type double stars. Only one is a confirmed binary (GRB 34AB). HJ 5453AB hasn't changed theta in almost 200 years and it's rho has only changed 0.1'. just judging by numbers alone (although I still have a lot to learn about it), STF 72 and STF 126AB seem to have similar proper motion, and their rho and theta are changing somewhat rapidly compared to HJ 5453AB. all are brighter than mag 11.1 and have separations greater than 23'. Jo

14. Collaboration (continued) Although this data is from a different star than that of the previous conversation it shows the way that the student receives the data when fully processed at DRO, however it is encouraged that the student perform their own analysis, guided by DRO.

17. Conclusion Dark Ridge Observatory and the interactive work that is conducted between the students and the on-site SME really make a significant difference in the way the students both learn about science through astronomy as well as the way they get ENERGIZED for all their future endeavors. Dark Ridge Observatory and the interactive work that is conducted between the students and the on-site SME really make a significant difference in the way the students both learn about science through astronomy as well as the way they get ENERGIZED for all their future endeavors. It takes a lot of work and patience to accomplish first-rate astronomical science and in the production and presentation of their work into journals and speaking at recognized conferences and this is where Dark Ridge Observatory and student collaboration is really making a profound difference.
