Nightfall features a premium workshop on Saturday and free presentations throughout Friday and Saturday. The premium workshop requires a fee, preferably paid in advance. Space is limited but if seats are still available, the fee may be paid at the door.
We’re doing things a little differently this year at Nightfall. Rather than having one speaker present a 4-hour workshop, we’re having 4 speakers present one-hour talks on varying topics. Your admission price to the Premium Workshop grants you access to all 4 presentations. As a courtesy to the presenters, please arrive on time and do not leave early unless absolutely necessary. Presenters, titles and times subject to change. Check the printed schedule upon check-in.
The premium presentation this year includes the following talks:
Greg will present a compilation of some of the lessons he has learned in his 11-year journey from complete novice to somewhat advanced amateur astrophotographer. Some of the common issues astrophotographers experience as well as a few less common issues and the solutions he has chosen will be presented. Solving these issues results in clear improvements in the quality of the data captured and the processed results.
Greg is a retired electronic systems engineer. His first DSLR astrophoto was taken August 11, 2007 after his unsuspecting wife gave her permission to take the plunge into the bottomless pit this pursuit can become. Since then he has imaged using a variety of refractors, reflectors, and catadioptrics on both a mid-range and a high-end GEM mount using a modified DSLR and cooled OSC cameras. The pursuit of the best data gathering and processing has provided many challenges and lead to the resulting lessons learned.
Today’s low-cost, high-speed video cameras and powerful computers loaded with free software make it easy to explore the fascinating field of high resolution solar system imaging. But like other flavors of astrophotography, the devil is in the details when it comes to getting the best results. This workshop will cover the practical and theoretical requirements for image acquisition using a video camera, with the goal of understanding how to get the best data possible from your site and equipment. The processing of video files using freeware AutoStakkert! and RegiStax in combination to optimize resolution will be explained and demonstrated.
Tom Bash has been a Nightfall regular for over ten years. He started out in planetary photography in the 1980s with an orange-tube C8 and TechPan film shooting at f/200, so he eagerly adopted digital imaging during the webcam revolution in the 1990s. His images have been published in Sky & Telescope and Astronomy magazines, and many of his lunar images have been featured on the LPOD website. One of his lunar images was helpful in targeting NASA’s LCROSS impact mission in 2009. He has presented at imaging conferences and astronomy clubs, and he consults with Woodland Hills Camera & Telescopes helping their customers with imaging. He is an engineer working in the medical device industry and lives in Huntington Beach with his lovely wife Litta.
If you do visual astronomy in remote dark-sky locations, you need little more than a Celestron PowerTank or a similar battery to get through a couple nights. But what if you’re an imager with a thermo-electrically cooled camera, a laptop, and all the other items that require power? You will need much more than a few amp-hours of power. In this presentation, Daniel will cover the basics of calculating your power consumption and will review some current (no pun intended) technologies to help get you through multiple nights of imaging when there’s no AC power nearby.
Daniel started in astrophotography in about 2001 with the purchase of a used SBIG ST-7. While he currently has an observatory at GMARS, he still enjoys getting out to remote locations to enjoy darker skies and the solitude of being in unpopulated areas. You can see some of his images and current equipment lineup at californiastars.net.
Why do we dither? Why do we guide? What is image calibration? What does it mean to stretch a linear image? This is a workshop about image acquisition and processing, emphasizing not how it is done, but why. An imager who understands the concepts behind why we need to do certain things in imaging applies the procedures more intelligently and efficiently.
Alex has been coming to Nightfall for twenty years. He is an Astronomical League Master Observer, past President of Riverside Astronomical Society, past Board Member of RTMC Astronomy Expo, one of the founders of The Astro Imaging Channel, and an RTMC Merit Award Honoree. He has presented in numerous venues, including Nightfall, RTMC, many clubs, and the National Parks. He has published articles in Sky & Telescope Magazine. Alex is a retired teacher and high school principal, has traveled extensively, and lives in Moreno Valley with his supportive wife. See alexastro.com for more.
