Flats for astrophotography, lets do the maths!

Update May 21!

I am slowly in the process of demonetizing all my videos, I was never in it for the money or the glory. I just like to help people. This way you can rest assured i'm not making a video only to trigger an algorithm or as click bait. I have been a bit disillusioned with it all lately, and hopefully this will help.
Instead if you wish to support me you can buy me a coffee or beer instead :) entirely your choice though!

This video is one of those videos, the ones you kind of don't want to do...but full of useful information (hopefully!). In this video i talk about bit depths, working out ADU ranges and the maths behind it, target ADU's and briefly touch upon how i take my flats.

Things to note: if it ain’t broke, don’t fix it.

It’s important to note the characteristics of your sensor, so whether it’s 12, 14, 16 bit etc

It’s also super important to know how your camera behaves with the capture program you’re using. Eg is it running at its native bit depth or being scaled up to 16 bit?
For example an Altair camera being used with APT will stay at its native bit depth. But a zwo camera with APT may be scaled up to 16 bit.

This video applies to dedicated Astro cameras mainly, but I’ll do one for dslr soon :)

For those who are total beginners, flats are calibration frames that we use to calibrate our light frames. I'll do a much more in depth video on calibration frames soon
