I purchased this several years ago so I could do nearly full aperture viewing with my C6-R.
Currently the aluminum cell is sitting in a hack sawed C6-R dew shield with a light press fit using spacers aound the cell. It is easily removed. It sits in an foam lined aluminum case with a lint free optical cloth protecting the front surface. Bottom surface is safe high in the dew shield.

It has provided me with amazing views of prominences and filaments over the years but it is all but redundant since I purchased a smaller ERF I use with my 127mm apo.
The difference an ERF makes on solar viewing is substantial when obeserving greatly reducing the heat issues all my refractors have faced while viewing in Ha. This being the yellow ERF it will also work on wavelengths other than Ha which is why I purchased it this way thinking I would move to other wavelengths like sodium D.

Has very little dust and no noticable defects. It’s a direct fit on for a C6-R

$500 shipped conus with the case included. I can remove it from the dew shield mount and chuck it of if need be.

I will I’ll attach pictures in a moment. My phone pictures are too large.
