Thanks! I thought about that but it looked like the IR glass was just a very thin cap at the end. So I didn't think it would help much. Now that you've cut out the Q IR cut filter no need to mess with the lens!

It's a 1.2mm fisheye 220 degrees. I just wanted a REALLY wide circular FE lens on the Q!
It looks the same as this one:
https://www.aico-lens.com/product/1-2mm-16mp-4k-fisheye-lens-ac1612mm/
So I will probably cut out the IR filter in a spare Q "sensor guts" that I have laying around and then try to connect that to the "rest" of my Q.
This way I can always switch back the original if I want to .. BUT I was thinking that it may be even easier to just swap it out with an action cam lens (also M12 mount).

This is great to know how easy it is to remove the IR cut filter. However now I wonder if it is still worth doing as a cheap action cam will also accept the 12mm board mount lens..
How is the IQ of near-infrared images with the Q / Q10 ?

Good find! This removes the IR cut filter by literally cutting out the glass! I was hoping that someone figured out a way to remove the whole retaining frame that the IR glass sits in .. to avoid the broken glass mess!
In any case it's the retaining frame that is in the way of my 220 FE lens to focus to infinity.

Jah BLESSed the M57 Nebula!! lol ;)
Very perceptive of you geo444!
I'm not sure I understand, you are not able to access my site?
You shouldn't have any trouble accessing a wordpress.com site unless your local provider is blocking it for some reason?
I'm really curious how you removed the IR filter? Is it just glued on, and you pried it off? I didn't want to force it since it's attached to the SR unit!
You've done some really phenomenal work with the Q continuum my friend! :)

Hi geo444, great astro work with your Q10 !
I am also interested in removing the IR cut filter over the Q sensor.
In my case I'd like the extra spectral sensitivity and need the room to mount a very short back focus fisheye lens, but haven't been able to see how to easily remove it.
If you achieve this, please let us know!
I disassembled mine, you can see here (along with exploded diagrams):
