Will an IR cut protective window affect narrowband imaging

robonrome

Hi I have the asi2600mono.... long story short I scratched the 60mm protective window and ordered a replacement from zwo and juts received and installed... only problem is I ordered the IR cut version by mistake instead of AR... I do mainly narrowband band imaging SHO although sometimes LRGB... I'm trying to find out whether the IR filter will cause problems or whether it will be ok... looks like the upper end of the pass band for the IRcut is ₆₇₅ for maximum transmission... and SII filter would be hard up against this though I think ok? What about any likely halo/reflection effects... better worse or neutral? Thanks robert

If you ordered from our website, you can submit this on https://support.astronomy-imaging-camera.com/ in "Order" and enter your order number to see if there is a replacement can be arranged.

Thanks. I was more interested in whether it would still work OK. Seems it will but may lose a little signal. Yes I ordered from ZWO website direct, I've ordered the AR now in any case so will have both.
