Didn't the old user manual for BYE 1.0 and 2.0 instruct us to set the camera dial to Tv for taking flats?  (My memory is failing me...)

Nope... both TV and AV are 100% possible in M dial mode.

 

If you take AV Flats you can have the DIAL set to M or AV.

 

If you are not satisfied with the camera chosen duration in AV then you can take TV images for your flats.  If this is the case you can take TV images with the dial set to M or TV.

 

Hope this helps.

Thanks.  I thought my memory was faulty.

In AV mode the camera is in control of duration. 

 

Is your dial in M or AV when you take flats?

[gianpri]

When I take the flat, shutter is in AV-Flat mode and Dial is AV.

The camera is 100% in control of the duration when taking AV pictures.

 

If you need a different duration you need to use TV value instead

I think Giovanni's original question about file naming is still open and I have same question.

 

It seems the BYEOS File name when taking flats using BYEOS Shutter set to AV-FLAT with the Camera set on AV always defaults to "1s" no matter what the actual shutter speed.

 

Example : Camera set to AV, shutter speed determined as 1/40 by camera, filename given using my filename settings as:

 

Object_FLAT_1s_200iso_Temp_Date_time 

 

And for comparison , when I then take a set of Dark Flats with manual setting to ensure the exposure is 1/40s, the filename changes to:-

 

Object_DARK_FLAT_TV1-40s_200iso_Temp_Date_time

 

I think it would be logical and useful that the FLAT filename reflects the actual exposure it was taken at correct?

 

Thanks,

Hmmm.

 

It does seem like a bug.  However, it is a bit trickier to put the exposure duration into the file name when the duration is determined by the camera.  It would require BYE to read the actual exposure from the EXIF data.  But what if the user has selected to "Skip Read EXIF data" in the settings?  Then perhaps put AV, or no exposure value in the file name.

Yes. looks like this is a bug.  Great testing BTW
