The transit of Mercury on November 11, 2019 shot from San Francisco, CA with a Sony RX10 IV with an ND5.0 filter (and a better filter adapter than this one).
I have a 58mm ND5 filter that I bought to photograph the 2017 solar eclipse. It worked pretty well for that with my Sony RX100 V, but now I want to use it with an RX10 IV (which has the advantage of a 600mm equivalent zoom). The RX10 accepts 72mm filters and I want to try and photograph an ISS transit which is happening sooner than I can get hold of an adapter.
I figured someone must have done this before, but I can't find a file anywhere. It's a reasonably straightforward part - as the filter is smaller than the thread on the camera I just need a small cylinder which has a 72mm thread on the outside and 58mm on the inside. A step up adapter would be slightly more complicated to accommodate the larger filter size.
This makes a simple 10mm tall adapter and you would just need to change the thread sizes to make it work for pretty much any combination of camera and filter (most filter sizes use a 0.75mm pitch as shown above). The vignetting is pretty extreme with the smaller filter and the size of the adapter. For this application I don't care, I'm only using the center of the image. If it's a problem for your application then it might be worth reducing the height of the adapter, at the expense of making it harder to detach from the camera.
Here is the adapter STL file on thingiverse.
After all that, I missed the transit by a couple of seconds. I thought the clock on my phone would be accurate enough but turns out it's 5 seconds off. So memo to self for next time - shoot over a longer window, or just take a video.

The three timelapse videos edited into the version at the top of the page. The first one was shot on a GoPro. The second is from a Sony RX100V with an ND5 filter and the third is the Sony timelapse processed to keep the sun at the center of the frame.

A love triangle set in the turmoil of post-graduation. Well written but left me a little cold, I just didn't care for the characters or the sudden resolution.
