FLAT with canon help was created by Andrea

Hello everyone. I'm finding a lot of ptoblems taking flats with my canon 60d.
On APT I set the canon to AV and APT found the correct time immediately. Here I do not understand the correct procedure for acquiring flats.
If imposed a ADU value of 6000 with a range of 1000, the exposure time remains 1 second in the exposure list and there is no button to acquire the flat and have the time calculated.
Please give me some clarification on this.
PS also understand if you can do it in RAW as well as FIT.
Thank you very much

Andrea,

have a look at this. Scroll down to "Exposure Modes". The driver can handle BULB and M mode, AV is not supported. The details depend on your camera model, whether it uses a separate B mode in the main dial or not. Hope this helps.

Thank you so much for your answer, I had already taken a look at the page.
My question is more specific:
1 - I set the CANON 60d to M
2 - On the CCD page I select FLAT
3 - in the calibration imposed the desired ADU (I set a correct value for the linearity of the sensor)
4 - I expect that pressing OK ekos will start exposing to find the right time to satisfy my ADU

this doesn't happen so I don't understand how to proceed and I haven't found guides on it that explain well how to acquire flat.
Is it possible to have clarification on this? of course if I ignore the automatic calibration part, knowing that with my light whiteboard I have to expose for 0.77 seconds (given taken from canon histogram without EKOS) it works, but if I did not know the time how do I do it? or if I change the light source?
I ask once again for help at all! Thank you

ok I realized that once you set the adu leaving 1 second as exposure you start the poses and before saving the first flat makes the calibration of the times to get to the UDA set!!!!! However,
this in FIT if I put NATIVE (for me cr2) says that it can not find UDA in a non-FIT image.
so in this case how do you do it?
