Hi Everyone,
I'm just putting together all the bits I need to image with my QHY8.
I'll be using a Hutech IDAS LPS filter basically all the time. I'm wondering if I also need to use an IR blocking filter?
I've looked at the bandpass plots for both filters, and although I don't really know what I'm looking at it appears the LPS filter also cuts the IR.
See here:

So assuming I can seal the chamber with my field flattener do I actually need the IR filter if I use the LSP filter?
Cheers,
David.
