It left a huge smoke trail but vanished seconds later. Thanks to my astronomy app, I was able to see ...

SLR / Telescope connections

I am wanting to connect my Canon DSLR EOS700D to my 10" Dobsonian SkyWatcher go-to telescope but it just occurred to me that if I do the camera sensor will be exposed to the elements. Is there anything I can buy to fit to the camera or T ring that will protect my sensor from contamination?

Thanks,

Keith.
