In order to reach backfocus on my Coronado PST I have to take apart my zwo camera and I put a 3d printed adjustment ring on in.
The small glass protecting the camera sensor is always loose, and sometimes I have to put it back into place when fitting this adjustment ring.
Now some dust has gone behind the glass and directly onto the sensor.
What would be the safest way of removing this dust spot?
I cleaned my DSLR sensor in the past with the swaps and cleaning liquid.
Is there a similar approach on the ZWO sensors?
Would a dry Q-tip be a bad idea or is it worth a shot?
Thanks in advance
