Solar Filter for TV 102

The only accessory I feel I really want/need (for now) is a solar filter. I had an Orion glass solar filter for my ETX90 (sold both) that I really liked, so I want to stay with a glass filter. (I know some people prefer the 'fabric' filters, but I prefer the feel of a glass filter.)

Does anyone know if the Orion 4.5" glass filter fits the TV102? The diameter of the TV's dew shield is 4.75", but in some cases the size given is in reference to the objective lens.

If the Orion doesn't fit, are there any preferences regarding the Thousand Oaks Type 2 Plus versus the JMB Type A?

I have a Baader solar filter I bought from Kendrick. Custom fit to go over the TV-102 dew shield with 3 plastic screws to keep it tight. The contrast and brightness is stunning, providing the seeing supports it.

David...you can go to the Astro-Physics website and they give you exact instructions on how to make your own Baader film solar filter..they work perfect..I made one for my Pronto out of poster paper (black) using Elmers glue and the Baader film following the AP instructions..I bought a sheet of Baader film off astromart from Paul McCarl for $20 and I have made three filters using that one sheet..and they are very durable,,,and it just so happened that when I made the filter for the Pronto that fits over the dew shield, when I purchased a new Tak 78, it fit perfectly inside the dewshield for it, so one filter works perfectly for two scopes...give it a try..you can make it and it will dry overnight and its ready to use...David
