Mike;
    Very impressive! You have picked up a hair more nebulosity than a 30
minute W92 8" Schmidt shot does with tech-pan, with the detail of your
longer focal length. And it's in colour! Does this mean that you will be
spending less time with film? The H-alpha filter you mentioned - is this a
Lumicon filter, or a narrow band filter?
