Astro Camera Window Got Scratched - Here's What to Do

My ZWO ASI533mm Pro protective antireflection window got scratched. It is pretty easy to replace as you will see. This will work for any astro camera if you can find the right window. This is also a good time to replace the descant if it has been exposed to a lot of moisture. This particular window works on

Here is the part that I used

The window, which is a 32 mm round AR filter, is designed for the ASI1600, ASI294 and ASI183 series astronomy cameras. It is 2 mm thick and has a flatness specification of 1/4 wavelength.

cameras like the ASI2600 may need the larger window.

The D60 AR 60mm protection window protects the sensor from the accumulation of dust and humidity once it is installed. ZWO has designed the AR window to be compatible with the following ZWO cameras: ASI071MC Pro, ASI6200MM Pro, and ASI2600MM ASI2600MC Pro.

I really am impressed with the precision screw driver set I use by i fix it
