We have one of those ultrasonic bath washes where I work.
Your image gets briefly very sharp. It reminds me of visually observing. Not that we can see much in CaK of course.

Top shot JAPP! I have a similar issue at the moment with my IMX174 sensor with crud I cannot shift...

Re: 3-3-21 light bridge and microspots
Hi JAPP,
Do you mean the dancing white spots ? From my experience with my old camera it tells me those are hot pixels ...
I have them too and I clean them out in my image processing.
Interestingwise in your second animation they are dark so they must be some dust spots. I clean the chips of my cameras uaing Methanol, Aether and Isoprpyl alcohol by wetting optical paper. Just wiping from one side line by line. Never back and forth.

Re: 3-3-21 light bridge and microspots
Hi JAPP,
Great animations.
I clean my sensor with a lint-free cloth using the soft eraser end of a pencil to press it against the glass and rub it around. I then use canned ‘air’ to blow away any remaining fragments of debris. Several rounds of this achieves a perfectly clean sensor.

These are great animations
Stuart, don't you use a de-static gun from a record player as well?

Re: 3-3-21 light bridge and microspots
Ha...good point, Alexandra. Yes, when some of the dust bunnies are particularly stubborn and don't simply blow away, then I also apply a few squirts from an anti-static gun and that seems to release them enough for the air blast to do its job. As I say, it can take a few rounds to finally remove the last tiny piece of crud, but it's worth persisting.
I regularly clean my sensors in this way, and filters, barlows etc
