It turns out that this is not a simple question to answer. There are plenty of forum posts that suggest one gain/offset or another but the methodology behind those numbers is often opaque. In this post I'll explore the process I used to determine the “ideal” gain, exposure time, and offset settings for my situation. This process should work with common consumer CMOS cameras being used for DSO astro-photography. https://jeffpeterson.xyz/posts/organizing-files/ Sun, 24 May 2020 11:00:00 -0701 https://jeffpeterson.xyz/posts/organizing-files/ Like many people, I've been struggling with how to organize all the data I capture with my telescope. In a given session, it's not uncommon to come away with 10GB of data and hundreds of files. Proper calibration requires that the lights, darks, flats, and dark flats match perfectly. With some projects taking taking multiple sessions over multiple weeks (or longer), it's easy to lose track of which files go together. https://jeffpeterson.xyz/about/ Sat, 23 May 2020 12:43:00 -0700 https://jeffpeterson.xyz/about/ My name is Jeff and this blog is where I ramble about technology, software engineering, astronomy, and astro-photography. By day, I am a software engineer. By night, I explore the universe with a humble backyard telescope. I live in a Bortle 6-7 zone with an average SQM of 18.5.
