ASI224mc

[Krakon]

Hi all, I have just purchased a second hand ASI224mc, I bought it knowing that the AR window that covers the sensor was missing, would I be ok just putting the 1.25 nose piece on and a UV/IR cut filter  and leaving as is or should I replace the window?

TIA

You should be fine just using a UV/IR cut filter on the nosepiece. The sensor will be more susceptible to dust without the AR window but the images should be fine as long as the UV/IR cut filter you use is of decent quality.

Thanks for your quick answer, pretty much what I had thought, but thought I would check.

I  also own the asi290mc and use a SVBONY UV/IR filter with that, as I have to buy another one for this camera I am looking at the ZWO filter or a Baader, which of course is more expensive !

If I replace the window I would as far as I know have to get one shipped from ZWO themselves from China which will take an age? Do you know of any UK based retailers that would sell the AR window?

Maybe this?

You will still need IR/UV cut though as the stock AR window lets full spectrum through

Great thank you, after all the searching I did, I didn't find that.

Ok, I will get one of the two I mentioned in my last post, thanks again 👍
