Wish that worked with DSLR sensors!

That's good - thank you for the tip I found it incredidly difficult to get the epoxy resin to go in the right place and it really loved to form a whisker that went onto the image area I found warming it up a bit to reduce the viscosity helped. That was with standard slow setting epoxy - I haven't tried Maplin's potting epoxy though did consider it. I would have thought that it should be possible to take the individual parts out of the pack and put them in separate syringes. Then squirt out equal amounts from each and mix it on a non metallic board before dripping onto the job with a toothpick.

I already had a camera modified with a cold finger and Peltier TEC cooling but failing that I guess you could put it in the freezer. Probably the whole camera with the USB cable coming out past the seal.

Thank you I may warm this thread up again before long - I've just bought a duff 1100D to play with from ebay auction

I too will be interested if this epoxy resin works - I tried ordinary slow cure epoxy and that didn't. I had one debayered sensor that was fine at 20C but failed when cooled. Whatever is used it needs to be good down to at least -20C. Sometime I'm planning to have another go with an 1100D sensor as this is a better model than the 450D I have working ATM. The 450D isn't yet in use for astro imaging as I haven't finished the enclosure. I'm waiting on a replacement control board for my 3D printer as I shall be printing plastic parts to my own design. In order to reduce the optical path to accommodate a filter wheel and OAG I'm replacing the main plastic frame that connects sensor and shutter to the front of the camera.
