Dear Callum, i’ve tried with ‘barn door’ ‘scotch mount’ or say ‘screw mount’ technique, made it myself some projects but its seems to me sometimes get very good result but not always after several uses occur some errors… i’ve lost many film exposure… first time i was doing astrophotography with film DSLR & ‘screw mount’ is only my tools to do long exposure 🙂 I will try to collect s&t issue as you mentionedMany many thanks for writings Clear Skies!
