Even though you’re filtering out a lot of the light, it’s still a bunch of glass gathering light to hit a focal point, the sensor. And I’ve seen examples of sensor damage happening very fast. Definitely wouldn’t want to accidentally take a long exposure.
This is not taken with sunlight hitting the lens it was taken with a hydrogen alpha filter which is also different from the usual solar filters, the hydrogen alpha filters black more wavelength and pass only this specific wavelength so despite the image seeming very detailed it is only because the intensity is high relative to it being just a small band of wavelength so there is no risk of damaging the camera sensor
There would absolutely be a filter on the front of the telescope though, is there really still risk to the sensor
I honestly do not know.
