Users reports auto brightness stretching with QHY5L-IIc

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Using QHY5L-IIc camera, with native or ascom drivers

What is the expected output? What do you see instead?
Many users reports white/grey display output, even whith correct focus.
An auto-brightness setting seems to automaticaly adjust levels, making the 
image difficult to read and/or making selection of a guiding star impossible.

What version of the product are you using? On what operating system?
All PHD1 & PHP2 version prior to 1.13.5
All windows versions / No idea about other OS.

Please provide any additional information below.
A simple checkbox to disable the auto-brightness stretching mode would solve 
the problem.

Developers do not own all the cameras supported by phd2. Unless you help us out 
by showing us the problem, we really cannot do anything about it.

Please attach one or more images from the camera that demonstrate the issue. 
Use File => Save Image in PHD2 to save the image, then click the "Attach a 
file" link in the issue tracker to attach the file to the issue report.

On these captures you will see the issue. 
The camera is covered with the cap. 
When you uncover it, it's almost the same making it difficult to see stars.
Sometimes, the brightness is OK for a few minutes, then it's white/grey again.
It seems that a perfect focus resolves the issue sometimes, but not always.

I made a mistake on my first message, there is the issue after v 1.13.15, 
including all PHD2 versions.

>>> On these captures you will see the issue. The camera is covered with the 
cap.

That is not really useful here. The issue you are reporting has to do with 
trouble seeing guide stars, right?

What we really need is an image that helps us see the issue you are seeing! In 
other words, you need to attach a fits file *with guide stars* that 
demonstrates your problem of "making the image difficult to read and/or making 
selection of a guiding star impossible".

Correct.
I'll make another capture as soon as the weather will be good.
Thanks again.

Further tests tonight show that the issue is solved using latest PHD version.
Please close the issue.
Thanks and sorry for the inconvenience.
