It's an older dslr but its all I have.
The camera was fine earlier but I tried taking pics of this lunar halo.
I switched the speed to bulb and wham...
It isn't a necessity as I don't shoot porn for a living but it is one of the few things that brings me joy.
Any suggestions would be appreciated.

Thanks
