Bias Problems

[cuivenion]

Hi, I'm a newbie so I'm going to have a lot of questions. Here's my first, I've been using this guide:

However my Master Bias just looks a blank gray image when auto stretched, nothing like in the guide, and my Super Bias looks like this (See Attached):

Does anyone have any idea what I'm doing wrong?

Hello,

Try viewing the superbias using the so-called 24-bit Lookup Tables mode. Press the "24" button located next to the "Enable/Disable Screen Transfer Functions (or from the menus: Image > Screen Transfer Functions > Use 24-bit STF LUTs).

Also, take a look at What is best practice using dark frames with an uncooled DSLR? if you are using a DSLR camera.

That's great thanks, here is the bias now. It looks OK to me, what do you think?

It looks good to me too

Thanks!

You are welcome!

Please ignore (or leave it for later) the thread link I provided earlier. You may better take a look at: For beginners: Guide to PI's ImageCalibration. This is what I had initially in mind!
