Looking forward to see what this filter does.
Joe, perhaps you can help me out. I contacted Baader about this, but who knows how long it will take for them to get back to me.
I recently bought a Baader 2" UV/IR cut filter online. Although the rest of my optics are all 2" and fit into each other perfectly well, this filter does not screw into my focal reducer or my visual back. Are there special adapters or threaders for certain 2" filters? It seems the filter is about .25" smaller than my 2" pieces.

Joe, was it a Celesteron visual back?



Andy.

My filter came in....





In pristine condition, it arrived quick...



But...it's a lot darker than I anticipated it would be. A Number 47 Purple, it's very deep...



...as demonstrated by Shirley Hemphill and Esther Rolle.

I think it will be good for solar contrast with the while light filter and perhaps with the full Moon...but I dunno about planetary.
