Neutral Density "Solar" grade filter for DSLR

[KennySharp]

Hi,

I am looking for a ND filter that I can screw onto the lens (62mm diameter required) of my DSLR for solar observing. I (think I) want the equivalent of Baader solar film (3.8 / 5.0) in front of my camera but as a screw on lens rather than having to cobble something together with cardboard / astrosolar film and/or Cokin ND filter holder.

I have been doing lots of searching online and can find varying strength ND filters but can't appear to find one stronger than ND3.0. Also not sure whether I would need to also use a UV filter with this.

The intent is to use this setup for: a) timelapse of the upcoming (partial) solar eclipse and imaging sunspots (without a telescope).

Any advice/thoughts on this would be appreciated.

Meanwhile, back to Google.

Cheers

Kenny

Something like this:

and this (but obviously the Sun rather than the Moon.

There are glass filters from Thousand Oaks and others. Not sure if they come in that size.

Thanks. Found this though it doesn't state the strength, it is clearly aimed at solar observing.
