The delicate process of ....

[David Smith]

Constructing an ND3.8 photographic solar filter

Note the essential items, coffee pot, ND3.8 film! There is also a good strong cuppa just out of shot.

As long as it's only coffee

Looking good! Strap it on tight: I could never relax when I used mine on the 10" scope.  In fact, I only dared use it to line up for imaging:

You obviously have a Blue Peter badge Iain

Oh yes, I admire David's professionalism in his construction, but it's amazing what you can get away with using sticky-backed plastic

Here's one I made earlier for 10" SCT, mind it did take a week to make it

Tidying up is the worst mistake you can make, never find anything after that

[Pete Presland]

Looks very good, looking forward to seeing the results. 

[David Smith]

Thanks Pete. I had hoped to test it today but didn't seem a lot of point on a blank disk.

Looks like a well made filter David. Hope there is something interesting on the disk soon to see how it performs.

[David Smith]

Me too! I have plans to try it with my #56 Green, UHC and OIII filters. Depending on how it performs I may add a solar continuum filter to my armoury.

Nice construction, Dave.

Charl, your scope room looks like mine.
