ISSUE

How do I change the size of the subframe CCDSoft uses to autoguide?

RESOLUTION

Using the registry editor you can change the size of the subframe CCDSoft uses to autoguide. Under most circumstances the default value of 32×32 is fine. Software Bisque does not recommend changing this default setting as it may cause unexpected problems like losing guide star while autoguiding, with other camera methods like “Move To” for the guide star, etc.

1. Exit CCDSoft.
2. Start the registry editor (Go to Start, Run, type “regedit” without quotes and choose OK).
3. Navigate to the key HKEY_CURRENT_USER/Software/Software Bisque/CCDSoft.
4. Open the key above and scan down until you find the name of the camera you are using. For example “SBIG ST-2000XM Guider” if you wanted to change the “Autoguider” setting or “SBIG ST-2000XM” if you wanted to change the “Imager” setting.
5. Under the desired camera, scan down and find the DWORD values named “m_TrackBoxHiRes.cx” and “m_TrackBoxHiRes.cy” and change their values appropriately (be aware of decimal vs. hexadecimal).
