Nebulosity 2 users

I know a few people use Nebulosity 2 for image capture and I'm wondering if you have noticed the same thing as me when taking flats?

I use an EL panel, so in theory the light output should be constant, when I set up to take a set of flats I use the 'preview' function and pixel stats to set the exposure time. So say I get a reading of 22000 ADU for 5 seconds, I then set it to run for 30 exposures and hit the 'capture series' button the subs then come in at way less ADU than the single capture so I have to abort the series and adjust the time up by a .5 second or so to gain the extra signal....Has anyone else noticed this or is it just me?

maybe try doing an actual capture of 1 image rather than preview. Get your settings right and then run the series.

The preview is a capture - it just doesn't save it to disk.

I'm not botherd by it - now I know its happening - I just wonderd if anyone else had noticed.

I guess that wont make any difference then.

I use dslr so I don't even bother with Neb for my flats. I do them straight on to the camera as it is a lot quicker.

Yep, I noticed that Martin, its almost like the preview is binned, but without the binning

I have also noticed that. It does appear to be, as TJ said, binned without the binning. I havent tried to find a setting to change it as I will just do one capture after I do the preview to see the difference and adjust as you do. Craig is pretty good about responding in response to questions - you might want to shoot him a message and see whether or not there is a simple setting change that can fix it for you.
