Hi Mike,I’m always reluctant to blatantly plug a book I’ve written, but asCallum wondered if I’d like to comment, well, Chapter 14 in my book’Hunting and Imaging Comets’ does cover this topic…..However, Denis has already pretty much answered your questionalready….. To go into great detail, well, it’s a bit of a minefieldto be honest, but, as Denis says, CARA (Italians) and Mark Kidger’sSpanish group are the experts…..However, their techniques varyconsiderably, with the Italian group requiring mainly precise, filteredwork and Mark’s group using a more user-friendly approach which lessadvanced amateurs will prefer……Hope this is of some use…..Regards,Martin
