Hi Chris
I used to have a 1000 Oaks glass solar filter for my Vixen ED102S 4” refractor and although it is a top quality, well made filter, I never managed to obtain any decent images. This might be down to user error, poor seeing, etc., but I did not find the images crisp and I also had evidence of some ghosting, as if I was getting an internal reflection from one of the glass surfaces. The 1000 Oaks filter did produce nice, deep orange coloured images though and it has an excellent reputation. There is also a safe and secure feeling about having a substantial, professional, filter on the front of the telescope.
Since I moved to my home made filters using sheets of Baader solar film, and in particular the photo density film (not for visual use) my images have been excellent; crisp and full of detail although this does depend upon the day time seeing as well of course. The Baader film does produce a whitish/blue solar disc which may not be to everyone’s taste.
If you are going to make a visual filter and a photo filter, make sure you label them clearly so you do not accidentally look through the photo filter.
Cheers
Dennis
