This is an announcement for the Symposium on Telescope Science held the week before the RTMC Expo meeting in Big Bear, California. The meeting is usually held the week before Memorial Day weekend but since RTMC has decided to float with the new moon the Symposium will be held May 11-12, with RTMC on the weekend of May 15, 2010. I would like to encourage any Utah astronomers that are interested in doing Science with their telescopes to attend the Symposium. There will be a number of papers spelling out projects that could be done with your equipment as well as an opportunity to network with many professionals that need help with their projects. If you have some results from a project you are doing and would like to submit it, the deadlines for abstract submission is March 14, 2010 with papers due April 11, 2010. The meeting consists of an opening day with two workshops followed by two days of technical presentations. The two workshops on Tuesday, May 11, will be 3 hours in length. The first workshop will be given by Olivier Thizy, President of Shelyak Instruments. As many of you know Olivier is a very dynamic speaker and his company manufacturers the LIHRES III and Star Analyzer spectrographs. He has a keen interest in Be type stars and has in the past, presented at SAS Symposiums some of his work. This year we have asked him to give a workshop on the practical aspects of spectroscopy using spectra he has taken with his instruments. Toward this end he has selected two parts for his presentation: 1/ Measure the temperature of stars using low resolution spectra (he will provide raw spectra taken with the Star Analyzer), using the Planck curve function. This should take about 1h30 and software used will be IRIS & VisualSpec (free software). 2/ Measure line profiles (Line center, Equivalent Width, FWHM, V/R ratio...) in high resolution spectra and link to the astrophysical meaning of those measures (for example in Be stars). This should also take about 1h30. He will mainly use VisualSpec there and provide spectra for people to use. The second workshop will be given by Richard Berry, co-author of the popular image processing book and software, The Handbook of Astronomical Image Processing. The workshop is called The Calibration of a CCD Camera. It will be a hands-on workshop with the participants divided up into 5 groups, one of which we will ask to bring their CCD camera and control computer which will be used by the group. The other members of the group will be taking and reducing the measurements on the camera. Controlled light sources will be provided to each group for these measurements. Most of us typically have an idea about the gain, read noise, bias, linearity, dark current, conversion factor and uniformity of our cameras, but how many of us have actually measured these parameters? By attending this workshop you will not only learn how to perform these tests on your camera but what each parameter means and what effect it has on your images. The cost of each of these workshops will be $50 each payable in advance. As the attendee list is finalized we will send out links to each so that the required software and test images can be downloaded and installed. The cutoff date for registration for these Workshops will be May 5, 2010 in order to allow attendees to have the required software pre-loaded onto their computers. The workshops this year are a continuing effort to bring our Symposium attendees information that will jump start and/or fine tune the use of their equipment in the pursuit of astronomical science.
