this was the last image run i got on my ASI camera. that black crap surrounding the sensor deposited more crud this morning so i tried to clean it off - well its like i haven't done this 100's times before. i now have crap on the actual sensor under the glass slip, and the slip is now cracked i think - bloody stupid thing
Nice detail there Dave, bummer about the camera, although I suppose it's better to trash the ASI120 than something more expensive. I wonder if ZWO do repairs, or is that glass user replaceable?
Very nice detail in that first shot Davo !
So sorry to hear about your broken camera mate?
Far out.
yeah not happy - but you get what you pay for sometimes. the DMK is rock solid, but the speed and very pedestrian....

Sorry to hear about the camera. I hope you can get a satisfactory repair.
Al.
i may just leave it for a guide camera - cost more to ship it than its worth
I just wish it was made without that black crap inside it
Great shot Houghy. I have read CCD sensors are pretty tough. They are not easily scratched etc. I would remove the cover slip carefully and try to blow off dust etc. Try to put a UV lens protector over the whole thing so it doesn't get dust on it. Dust would be the problem. My FLI cameras don't have cover slips. Its an option. It increases QE a tad and reduces some minor haloing. It also improves performance in a fast system.
Magic details within them sun spots David !
That black stuff looks a bit like expansion joint for concrete ? what ever, its flaking everywhere, so understand your frustration.
Can you take that out at all, maybe spray with some flexible sealer, smear over with rubber glue or silicone to keep it from fragmenting etc ?

not too sure why it there but i would love to get rid of it
David, I don't know what they are, my ASI has these whatever since I received it. And I gave up to clean. I tried all. And when I say all, I want mean really ALL !
Some times I think that I can move them on surface. Some times they stay there forever. I lost more time cleaning the ASI sensor than using the camera. Now I use it only as guiding camera.
I don't like ASI camera to imaging. It is not a good camera to do this task. I never will buy their products, again. I hate ASI!
David are you sure that these thing are really under the glass.
In any case they can be simply removed by using a flat.
It does look like a rat has been living in there.

wet cleaning with isopropol OH doesn't remove them

Hmmm I just checked mine, no sign of any crap in there at all.
I do remember a long streaky mess like in your shot once but it cleaned off.
The motes are easy checked. Take a flat, inside after tea using a 3x Barlow.
Then carefully mark the position of the camera on the Barlow, remove the camera and clean it, try not to over wet the area using a cotton bud. Replace the camera in the same position, as marked, and take another flat. Same settings.
Process them and blink compare them in PS. If there is little or no change the issue is under the glass plate. If they have altered position, gone or got worse the problem is out side and can be cleaned.
BTW I do not think, in fact I know, that the long streak is NOT a crack.
