SPCC and seestar s50

[geo1970]

The telescope I use is the seestar s50 . I would like to ask when I use the spcc what to put in the filter options and in the QE curve ? The sensor is the IMX 462 which is not available as an option. For filters the telescope has built-in dual narrow-band light filter (bandwidth OIII 30nm/Ha 20nm) . Do I leave the options as they are or choose something else? Thanks for the help .

These are probably the best settings for the S50 with the LP filter selected:

Thank you for help .

Although the L-eN filter bands are about half the width of the S50 LP filter, I think it is a close enough match for SPCC. If you can image without the LP filter, just use the Sony CMOS -UVIRcut without the L-eN.

I have found it difficult to locate properly attributable data for the SeeStarS50 LP filter response. The best data I have found is from this post on CN:

I have manually constructed a FilterManager .csv file for this data (attached).

The process is as follows ?
I export the file to a folder.
I use the filter manager.
If so, what options should I put in the filter manager?

I can see the new filter in the Qurve explorer box, but how do I pass it to the scc ?

You use the Curve explorer to simultaneously display the SeeStar filter and each of the Sony CMOS -UVIRcut filters in turn (for R, G and B) [use Ctrl-click to add a filter]; it will look like this:

Then click the combine icon

.
You will be prompted for a new file name. Dont forget to include the channel letter in the file name:

When you click on OK the new combined filter will be displayed:

Do this three times (once for each channel). When you close the curves explorer you will get a message:

Once you accept this, the new filters will now be available in SPCC:

If you "Import CSV filter definitions" you will loose all the standard filters. You need to "Merge CSV filter definitions" to add the new filter to the existing filter set. Of course, if you added the new filter to a folder containing all of the standard filters, then import will be OK.
