This instructable is trivial, but that's where the beauty lies. Using cheap and readily available filter step-up adaptors and UV filters you can fit solar filters to your equipment.
- Protects film from accidental scratches.
- Wind protection to stop creases.
- Holds filter flat and close to lens to stop internal light reflections that can create image artifacts.
- Looks clean and professional.
- Made using cheap and readily available parts.
- Securely holds filters to reduce risk of them slipping and exposing your eyes to magnified UV.
Important safety feature when using with telescopes or binoculars!
This technique can also be used for colored gels!
Step 1: Materials
- A cheap, thin "step up ring adaptor".
Used to attach larger filters to cameras. ($1.20 on ebay)
- A cheap, thin UV filter. ($3 each on ebay).
You don't really need the UV protection, you just want physical glass to protect the film.
- High quality solar film.
Do NOT go cheap here!!!! 8x8 on Amazon is $18, but it's enough to do a lot of filters. Also, you won't have to worry if you mess up the first attempt.
- Clean, smooth surface that you can cut on.
You will be sliding the filter film around on it and you don't want to scratch it. Non-corrugated cardboard, felt, or paper with cardboard under it.
- Lens cleaning cloth
Again, do not buy solar film from unknown vendors. If you get sold something that isn't really cutting out the UV, then you will damage your eyes and not even realize it until it's too late. It's not as important with digital cameras that use LED screens, but anything involving your eyes and the quality becomes critically important.
