Solar eclipse

I'm having trouble finding a solar filter for the upcoming eclipse. Mostly because I don't know what to search for. Can anybody help.

I need a 77mm filter for 100-400L ii
1 ACCEPTED SOLUTION

I purchased a thousand Oaks 12" X 12" filter sheet. 

I made my own filter holder. To fit the lens hood. That way I can just remove the hood when not using the Solar Filter and just use my CPL when safe/er.  

Here is how;  TOOLS:  Exacto knife, Solid thin cardboard, Double sided scotch tape, Protractor, and Tape measure. 

                       I measured the lens hood diameter end which attaches to the lens.

                      Cut out the diameter of a thin solid cardboard. Then made another circle about a 1/4" smaller.

                      Then made another circle about a 1/4" smaller and cut out the cardboard.

                      Cut two cardboard pieces.

                      Cut the Thousand Oaks Solar film the outside diameter of the cardboard.

                      attached the double sided scotch tape to both pieces of cardboard.

                      Adhere the film between the cardboard. 

                      I then using the Exacto knife trimmed to fit the lens hood about 1/3 to half way down.

                      Double check that you are not allowing any sunlight to pass between the lens hood and the filter.

                      Good to go.

                    ByTheWay, the filter is not entirely tight but appears not to be an issue. When I tested in direct sunlight.

ThousandOaks.com is a supplier. They are out of stock on 77mm filters, but they might still have the filer material that you could adapt to lens.

 

There may be others, but I don't know.

Do you know if a different supplier that has threaded filters. I don't have enough spare time to adapt to my lens. Thank you

As I said, there may be other suppliers but I don't know.

Out of stock for now, but should be available before the eclipse.  Cannot attest to its effectiveness since I have not used it myself.

It's made by Thousand Oaks.

Did you try getting the sheet directly from them?

I did not and I don't wants to get a sheet. I'm looking for a threaded filter. I'm more of a plug-and-play player

I offer this input:

 

1. I ordered my filter from TO back in July. At that time they were running three weeks from order to delivery, and they were claiming instock.

 

2. now their site is showing 77mm out of stock.

 

You might want a  Plan B. Its pretty simple to rubber band the filter over the front of the lens just incase the other vendor can't deliver.
