Premium Workshop: Compelling Astrophotos – Working with Detail & Noise

Nightfall 2022 Presenter - Ron Brecher

Dr. Ron Brecher of will be our premium presenter for 2022!

The most compelling deep-sky astrophotos have just the right balance of sharp details and smooth overall texture. But getting that result requires that only legitimate structure is enhanced, while dialing down or preventing buildup of noise. Join Ron Brecher for his two-session workshop geared toward helping you get the best from your astrophotos. While he’ll use his preferred image processing software, PixInsight, the concepts apply to any image processing. The morning session will look at techniques to use in the linear state (before “stretching”). After lunch, Ron will focus on techniques that can be used after stretching, on nonlinear images.

Ron is an avid amateur astronomer with 20+ years of experience. His photos and articles are regularly featured in print and online magazines, journals, CD covers, calendars and more. Ron writes for astronomy publications in the United States, Canada, and the United Kingdom. He is a PixInsight Ambassador, and is the Technical Reviewer for both editions of the highly acclaimed reference text, Inside PixInsight. He is a Contributing Editor for Sky & Telescope magazine.

Ron is available for one-on-one online astrophotography tutoring and support, including equipment setup, troubleshooting and image processing with PixInsight.
