first two are for my 8"
Last one is the 8" and 11" that I need to add hold down eye bolts to.
I added the eyebolts to run safety cords through that I tape to the telescope body. I don't want these to come off while viewing.
Second, I made the optical hole smaller so that the hole is in side the diameter of the telescope optical as an added safety feature. It has not affected my viewing.
Third, as you can see it has wrinkles, this is normal and shouldn't be something to spend time getting rid of..
In fact, what I did was coated the smaller mounting mat board frame with spray on adhesive, layed out the film on a clean sheet of fabric taping the corners to hold it in place and set the frame onto the film.
Then I set the foam frame that is cut to fit snug on my scope onto it, then glued it into place.
I still have both eyes and all my sensors.
Pun intended.

One other thing. Before each use, hold the filter up to a strong light and look for tears or holes.
This includes when you build it although the chance of a hole in new film is very slim as they coat both sides of the film to avoid even pin holes.
Also when sighting the scope for solar viewing do not use your spotting scope in fact put the covers on it to be safe.
I mount the filter on the scope and then view through the lens mount to get the sun into view since you will be looking through the solar film. It seems odd but that's the easiest way to get it in view.

Wow that is brilliant. I'll order my film today and get to work on the frames tomorrow.
Thank you for being so patient with me on this. I think I'll use my Mirrored 600mm and the Meade 8" I still do not intend on using an eyepiece to look at it I'll use Live View.

The first filters I made using old UV filters that were cheap.
Unscrew the retaining ring add your filter sandwich and put it all together. Make sure that the ring fits the filter snugly to avoid light leaks. Cutting the double circle was the hardest part but made for a filter that is easy to store. We all have cheap filter cases laying around and I wanted to protect it.
It's pretty unnerving the first time you look through a homemade filter hoping you did everything right. Take your time and follow the directions that come with the film and you should be fine.
Good luck.
Oh yeah.. throw away that junkie UV glass..

That is exactly what I'll do then is use the worthless UV scratched glass filter frame for the 600mm. On the 8" I'll use 1" styrofoam and a piece of a file folder???

Photo mat board works really well. It's stiff and thick enough to resist bending.

Just remember, slow and steady. Caution is advised at all times..

Ok, off my soap box but remember you only have 2 eyes and they don't regenerate.
;)
Lastly, you want the 5d film that's rated for visual.
The 3 or 3.5d is only for sensor shooting and let's to much energy through for eye visualization.

Well the shot was oriented correctly on my screen. But I am at work.

Regaeding sighting the sun, an easy way to get roughly sighted in is to look at the shadow of the scope.
Just align it until it is a circle.

Good set-up. Can I use a glue stick to keep it on the OTA? Something I can clean off between uses?

I wouldn't trust my eyes to a glue stick.
I don't want the wind or some nosy kid to pull it off while I am viewing. You could always add black felt to the inside and make it snug to the fit but you still have to worry about someone accidently removing it.
Your eyes, your call.
