Sensor tilt adjustment - Forums

Hello again good people,

I am here with yet another question. I’ve been struggling with sensor tilt lately so i’ve been looking around the internet for solutions. I’ve found some tutorials on how to build a rig for the camera to shine a laser on the sensor and then adjust the tilt by looking at the reflection of the pixels. Here is a link to it: https://www.macobservatory.com/blog/2021/11/28/how-to-remove-sensor-tilt-from-your-astrophotography-camera-while-indoors
However i am using a DSLR and from what i found out is that laser can damage the sensor. My question is what is the difference with a dedicated astrophotography camera why doesn’t it get damaged? Is there a work around? Another technique more suitable for DSLRs to do at home?
Thanks guys

My question is what is the difference with a dedicated astrophotography camera why doesn’t it get damaged? Is there a work around?

There isn't. The sensors are pretty much the same. If a laser can damage a DSLR sensor (and I don't know for a fact it will), it will also damage an astro cam sensor.

Software such as ASTAP or NINA's Hocus Focus can diagnose tilt and backspacing error quite well. The important thing is to have a tilt adjusting device that can allow accurate adjustments while you enter rig is set up without taking the camera off. For astro cams, there exist good solutions like the Gerd Neumann CTU and the Photon Cage. Not sure what options exist for DSLRs. Lack of sufficient free backspacing will be a major issue.
