Which IR Pass Filter?

[The Lazy Astronomer]

Hi guys,

Thinking of getting myself an IR pass filter for some planetary imaging over the next couple of months, and wondered if anyone had any advice on what might be the best option?

My current planetary equipment is a 6" SCT with the asi290mm camera (although l may upgrade the scope to something in the 8 - 10" range for next year).

As I'm using a relatively small scope, and my camera is not particularly sensitive at higher wavelengths, l was thinking something like the Astronomik 642 might be a good choice? Any thoughts or alternative suggestions on that?

Thanks.

The dedicated ZWO filter is cheap and works fine on my ZWO290 camera.

I did pay more for the Baader one for my main imaging camera , a ZWO533mc

With that size scope probably 642 or 685
