Have you been able to find a graph of the transmission curve of the filter? Does the manufacturer's website or the company that you purchased the filter from have the pass-band information?
With the pass-band information you can create a file of filter transmission data for ST4 Imaging, as follows: [attachment=2376]
1) Open the Imaging System Dialog
2) Click the Filters button in the 'Camera' section on the left side of the dialog
3) When the 'Assign Filters...' dialog appears, Click the 'New' button on the lower left
4) Click the 'Read Filter Data From File' button for the instructions to construct the file
5) Construct the file containing the data for your filter. You must use the absolute transmissions here. The wavelengths need not be equispaced.
6) After you've saved the file, Click the 'Read File' button to read the filter curve data into SkyTools.
That should do it. Hope this helps,
