Hello,
Since the weather is poor in melbourne, I am spending most of my weekend time reading on diffrent narrowband filters.
I was reading through Astronomik CCD filter specifications where it says their CCD narrowband filters will also block IR.
If I get a astronomik ccd filter say OIII 6nm do i need to replace my QHY8's default IR filter with a clear filter? or can i leave the default IR filter?
Thanks in advance.
Regards
