Special Sauce and Dangerous Medicine: Getting the Best From Your Deep Sky Images

What Are the Odds? The Drake Equation and More

Ron Brecher ( has been an avid amateur astronomer for 20+ years, and began photographing the sky in 2006. His deep-sky, Sun and Moon images and articles are regularly featured in print and online magazines, scientific journals, CD covers, websites, calendars and more.

Ron uses PixInsight for processing his deep-sky shots. He offers private tutoring online, and teams up with Warren Keller ( to teach 2- and 3-day image processing workshops. Ron is a regular speaker at star parties and conferences in the U.S. and Canada.

Ron writes regularly for Sky & Telescope and other publications, most recently “Image Calibration” in the November 2019 S&T. He is the Technical Reviewer for both editions of Warren Keller’s, Inside PixInsight.

Ron captures his images from his home observatory in Guelph, Ontario where he and his wife Gail live with two dogs, two cats and two kids. In “real life,” Ron holds a PhD is a board-certified toxicologist with more than 30 years’ consulting experience in toxicology, risk assessment and risk communication. To round things out, Ron plays guitar and lead vocals in the R&B Band “The Exceptions.”

About Kopernik Observatory & Science Center, the KAS, and AstroFest
We are hoping you would consider being a part of our event. At this time talks are targeted for a more advanced group of amateur astronomers from Kopernik, and other astronomy clubs, as well as college professors, graduate and undergraduate students from area Colleges and Universities; as well as interested members of the public. Our AstroFest celebration will begin at 6 PM on Friday, October 25th, and concludes Saturday, October 26th (of course observing overnight if skies are clear). You can decide how much you would like to participate from one day or both. Camping will be available at the observatory or you can find lodging in Vestal hotels.
We are hoping for clear skies to observe after the talks Friday and Saturday, and sunny skies for solar observing on Saturday and Sunday mornings.  This will be our 6th annual KAS Solar Star Party that was founded by the late and great Barlow Bob (RIP).
At this event, we will support a swap meet if people are interested, and you are welcome to sell your astronomical items or trade with others that participate. We will provide a free spot under our Gazebo or dining canopy to do so (first come, first served). This year we will be featuring the sale of various telescopes and equipment no longer needed by the observatory – most of it donated in years past.
One of the purposes of this year’s event is to get others to visit us and see the jewel we have here in Vestal. Not-for-profit Kopernik Observatory is regionally known as a “Space Education Center”. We also claim to be the best sited, best equipped observatory in the Northeast US which is open to the public. We have three domes, one with a 6” f/12 Astro Physics Planetary Special (the second best of the batch of 25 produced) on a G-11 mount/clock drive and NGC-Max; one with a Celesteron 14” with a CGE computer drive and our flagship, a 20” Ritchey-Chretien with an OGS drive. On occasions we talk with astronauts in space on the ISS, Space Shuttle, and in the past, on Mir via amateur radio station.
Directions to Kopernik Observatory, 698 Underwood Road, Vestal NY: From the E or W – take Route 17 (Southern Tier Expressway – future I-86). Get off at the Vestal Exit 67 S (26 S) and proceed up the hill about 5.5 miles. Just past Vestal Center (alleged to be a 40 mph “speed trap”), turn right at the sign “Observatory 2 Miles” onto Glenwood Road. If you miss the turn, you will hit the Pennsylvania state line in about a mile – just turn around and go back a mile. Take Glenwood road a block to the first left hand turn (about .2 mile). This is Underwood Road. Drive up the hill 1.8 miles. Kopernik Observatory is on the left. From the N or S – take I-81 to Route 17 (Southern Tier Expressway – future I-86). Then follow directions from E or W.
