Howdy Astro Buddies,

 

I am thinking of making a Baader safety solar film filter for a pair of canon image stabilized binoculars. 
 

I have done a nice build for an SCT with the Baader film and I love it, but that had a lot of room for safety screws as part of the build that actually thread into tapped holes in the front cell of my SCT.

 

I’m trying to think of how to make a safely secured fit onto binoculars. I want something more secure than a pressure fitting. Thank you for your advice, insights, and any images you may supply!

yes - using 52mm - 58mm step up rings (I have the 10x42s).  I made cardboard rings that fits tightly in the 58mm opening with the solar film bonded to the rings.  Of course it needs to be well bonded to the ring and a tight fit so they don't fall out or get blown out by the wind, or else glue them in.  They thread into the main lens cells and work great - assuming you model is threaded.

While I've built many solar filters, for my Canon stabilised binoculars I bought glass filters from Seymour Solar, they have a screw for securing to the short barrel, and work really well.

My setup is not as elegant as Jonathon's but has worked for me.  I have a Burris IS binoculars and has a much shorter nose on the objectives. I used 1/2" baltic birch plywood and Baader Astrosolar film.

Hope this helps.

Thanks, Everyone! I really appreciate the details you all provided. I have to check and see if they’re threaded. I think they are. They are not mine, but I am planning to build the solar filters for them as a surprise gift for the owner. 
 

I’ll post some pictures when I can get to the project.

If not threaded you can make tubes that fit around the barrels.  I always tape solar filters to scopes and binoculars for added safety.

Yeah, I was thinking if it were threaded, I’d build off of that if practical. I’ll probably end up going tube style like the set more glass.  But I really do like the optical quality of the baader film I’ve used.

The Baader Solar Safety Film is the best!  I have Baader film for my binoculars and my SCT.  I have a Hershel wedge for the refractors.

My Canon’s have threaded barrels, and I use a pair of standard camera UV filters to protect the lenses just as one would do for a camera. While I can imagine adapting a screwed fitting to solar film, the glass Seymour Solar filters work so well I don’t see the point.
