Hello !!! I´ve been reading that some people recommend to use a UV-IR Cut filter with the ASI 071 MC Pro camera, but others don´t. What are the advantages/disadvantages to use this filter0? What do you recommend/think? Will you get better and pinpoint stars and colors?
I think ZWO doesn't add a typical UV/IR cut filter in their cameras as they started as a planetary cameras manufacturer. For planets, it can make sense to have the IR wavelengths to pass so as you can filter the light yourself - either want it - for e.g. Moon imaging with an IR pass filter or you do not want it - you add the UV/IR cut.
But for DSO imaging, there's very, very little use cases for imaging WITHOUT an UV/IR cut filter.
I have mine permanently installed
My opinion: in a color camera meant for DSO imaging there should be an UV/IR cut filter installed right away out of the box, not just AR-AR filter... (or whatever is there).
I will bring your suggestion to our development department, if they could consider about IR-CUT filter in the further.
Thank you for share!mslehv wrote:I obtained a dramatic improvement in image sharpness and star size with the use of ZWO's IRCUT filter. For the price, it's a fairly inexpensive experiment.
