ZWO ASI533MM Review + Bonus Tutorial

I've been using the ASI533MM on every clear night since May 2022, and this camera has done a phenomenal job!  I love how well the sensor performs, with no amp glow and a high Quantum Efficiency  This makes narrowband work much easier from my light polluted backyard!  In addition, this camera pairs perfectly with my SpaceCat 250mm telescope.  Thanks to the 2.7x crop factor of this sensor, I can fill the frame nicely with most nebulae and galaxies.

My only real problem with this camera is the square sensor.  This is fine for most people, but its not ideal for video (with a 16x9 ratio).  Also, the camera resolution is ~3000 x ~3000 pixels, which is a bit low.  However, I haven't noticed any real quality loss when cropping in. 

All things considered, I'd highly recommend the ASI533MM for anyone looking for a monochrome camera with a small sensor!

I also highly recommend getting the AM5 go-to mount.  It's a game-changer for astrophotography:
