ST-8300C - Red Color Problem

You didn't say what light source you used to take that image. It looks like you did it indoors so who knows what the color temperature of the lighting is. Could be reddish if incandescent, or greenish if fluorescent.

Of course you may have to tweak color balance. Your best bet for setting color balance is to image a G2V spectral class star and measure. A suggested method for our MaxIm DL software is described here:

You can do something similar in other software packages.

 

You can upload your image to our public FTP server to avoid size restrictions.

Be sure to let us know when you have completed the upload as well as the filename.

-------------

Windows XP:

You can login to our FTP server with these credentials to avoid transfer problems and size restrictions:

FTP Host Address: ftp.diffractionlimited.com
User ID : anonymous@diffractionlimited.com
Password : (NO PASSWORD)

To login, open "Windows Explorer", (Not Internet Explorer), and paste the following address into the address bar:

ftp://anonymous%40diffractionlimited.com:password@diffractionlimited.com

- Please *ZIP* your images, and use your name as the file name for the zip, i.e.: "myname.zip".

- Upload your ZIP file into the "INCOMING" folder.

- Once you upload your image into the "Incoming" folder, *NO* file will appear...this is normal.

- Please inform us when you have completed the upload

-----------------------

Windows Vista/7:

1: Click on Start button in Windows Vista/7 and then click on "Computer".

2: Click on “Map network drive”

3: "Map Network Drive" window will open. Now click on the link "Connect to a Web site that you can use to store your documents and pictures."

4: Now simply follow the step by step wizard to add a new network location. Select"Choose a custom network location" when given the choice of where to create this network connection.

5: Type our ftp address ftp://ftp.diffractionlimited.com and click "Next"

6: Check "Log on anonymously" then click "Next"

7: Once the wizard is completed, if it does not open automatically, click on the Start button in Windows Vista/7 and then click on "Computer", and you should see the FTP server listed under the Network Location. You can access it the same way you access any folder on your computer.

-----------------------

Third party FTP Clients such as "Filezilla" can be used to upload software to our FTP server as well.

https://filezilla-project.org/download.php

Once the software is installed, use the following credentials to connect:

Host: ftp.diffractionlimited.com
User Name: anonymous@diffractionlimited.com
Password: (NO PASSWORD)

Copy or drag your files into the window panel on the right to upload your files.

Once the files have been successfully uploaded, you will *not* see them in the Filezilla program but we will receive them.

Let us know when the transfer is complete.

Did you use the correct user details?:

Host: ftp.diffractionlimited.com
User Name: anonymous@diffractionlimited.com
Password: (NO PASSWORD)

As well as copy it into the Incoming folder?

You could also upload it to a 3rd party cloud file server like Dropbox, or Google Drive and send us the download link.

 

Does it only occur when you take an image with CCDOps? Have you tried any other software to capture the image?

 

You can try the MaxIm DL Pro 30-day demo version:

Can you collect some driver logs, and perhaps we can find the cause of the issue.

To collect driver logs:

1.) Open the "SBIGDriverChecker64" software
2.) Click the "Debug Log" button.
3.) On the "Configure Debug Logger" window, click the "All" button.
4.) Click the "Set Path" button and enter a name for the log file and a location for it to be saved to. Then Click the "OK" button.

Once it is configured for logging, try the testing again to reproduce the issue and send us the resulting log file.

 

You need to update your SBIGDriverChecker64 software. You can download the latest version from here:

Sorry for the delay, we collectively dropped the ball here.

I've looked at your raw TIFF image, and what is going on there is really bizarre. There is a sudden horizontal shift suggesting lost pixels. Then just ONE of the bayer planes goes dark, except in spots. Further, after that happens it looks like any pixel that exceeded a certain value lost 16384 from its ADU value. Sounds like a digital hardware problem... just a really weird one.

The only component that could possibly do something this bizarre is the FPGA. It could be caused by a power supply issue, or some intermittent problem on the circuit card.

Does this happen often? Or just occasionally? Does it happen at the same point in the image readout, or does it sometimes cover more or less of the image? Are you using the power supply that came with the camera?

What is the camera serial number?
