Salut Dominic

Je peut lire et ecoute francais, mais quand je ecris ou parl c'est
beaucoup de domage a la langue.
It looks like they are using 2 1/4" GEPE slide holders even though the
first photograph pointer shows a 35mm slide holder. A 2 1/4 holder (120
film) should cover the front of most lenses used for  constellation
work. I am wondering if a clear filter (like UV) ground against a piece
of plate glass with 800 grit or even 10 micron powder would give a
similar result to waht you are looking for. I may give it a shot this
weekend.
If you need a single 35mm GEPE anti-newtonian slide holder contact me
off list.
