IR pass filter or IR blocking filter


Recommended Posts

HI Dean

For a webcam -

IR pass is only recommended for mono imaging.

IR Block is ideal for imaging the solar system.

Neither has anything to do with modifying a webcam.

Modifying a webcam is mainly for advanced mono imaging of

the solar system and/or Long exposures for DSOs and that's a whole new

topic.

Hope that helps

The UV/IR cut is normally a coating on the webcams lens so you have lost this filtering when the lens has been repalced by the 1.25" nosepiece adaptor so you just need to add this back using a suitabel 1.25" filter.

Thanks for that

I’m new to imaging and just wondered what is involved in modifying for deep sky imaging?

Hi Dean,

This thread pretty much covers the SC1 modification on the SPC900NC webcam.

I'd recommend getting some lunar / planetary imaging under your belt before trying DSO imaging. Imaging equipment and processing can be frustrating and there is a lot to learn, but it will give you a great sense of satisfaction too when it goes right :)
