I did forget to mention
You will also need a remote shutter release, either wired or wireless. Working at these distances even the a shutter slap, let alone pressing shutter release button, can jog the camera enough to blur the photo. if you try and get a photo of the whole moon in shot you will be disappointed as most of the moon surface will be flat. Your camera on a steady heavy tripod will help and reallyI think necessary. I used my manfrotto 055XPROB with a 322RC2 manfrotto head.
Don't try taking a photo if there is the slightest bit of wind either. And a torch is hand to have nearby as well
Would I attempt it again even if I still had the lens? no. Doing it once was bad enough
