Capturing FIT flats for use with DSS
Posted: Sat Jan 11, 2020 8:44 pm
Hi,
I'm trying to capture flats in the FITs format to use with my lights in DSS. To do this, I need to really shorten my exposure time to get a nice histogram. I use an light panel and even at low setting I need to grab the Flat a 30ms. Problem I'm running into is when I capture the flats, it tells me it's grabbing the frames at 1.5 FPS? I wonder if this is resulting in overexposed flats?
Should I think about taking longer exposures by:
1. Building a diffuser to dim my light panel more.
2. Shorten the gain? - On this I was under the impression that DSS needs the flats to be taken at the same gain setting as the Lights. Am I right?
Thanks for the help.
