So the Mercury transit of the sun is coming up in about a month. It starts at sunrise around here and lasts 2-3hours. I was going to try and get some pictures of it assuming I can get out that day. Typically it is rainy that time of year on the westside, and I'm thinking to head to the eastern side of the state.

It's not as interesting as a solar eclipse, but I think it will be fun to see and try and grab a picture.

Any of you also going to try and capture this rare event?

Note: you need solar film to protect your eyes/camera ...just like an eclipse.

I have it on my calendar for the 12th early AM for a partial transit, was hoping for a weather window to see a little back dot on the sun that day

Looks like the Goldendale Observatory’s going to be open Monday from 6:30a to 10:00a
might be a better weather option the wet side

Would you stack two ND filters for this shot? Or do you need a specialized solar filter.
Would a 10-stop and 6-stop be enough?

Not sure, I bought a Meade Glass White Light Solar Filter for the last eclipse.

I don't have experience using ND filters for solar imaging. I've just used the solar films from Thousand Oaks and Baader. They cut the light by like 100k. If you can capture an image without saturation of the sensor then you might get ok results. The main issue with unknown solar solutions is that you don't know if it is safe for visual viewing with your eye. You could also cook your camera. Whatever you do don't look at the sun through an unknown solar solution (including camera  optical viewfinders). Your camera can be replaced, but your eyes can't!

Kite, yeah the observatory looks like a nice option if you can get there. Viewing the sun in H-Alpha is a great perk if they have that.

Also, some near realtime solar viewing links if you can't get outside on the 11th.

It might be.. or might have been..  I used an 18 stop solar filter for it..  It would have been interesting to see if that stack would have worked..  It might still have been too bright..
