Combining images from narrowband filters is often done using the
Hubble tri-colour palette, in which SII, Ha, and OIII are assigned to R, G, and B, respectively. I took this image in 2006 with 20 minutes exposure per filter from a remote access observatory in New Mexico. Martin Nicholson, Daventry, England.

When you and your friend Hannah from Eire claimed to have set up a group and tried to ask for others to help fund the filter use at the robotic telescopes, except Hannah wasn't in Dublin, as she was posting to yahoo groups from the self same modem you were. Not quite as well known as the nova scam that one. |

Not quite as well known as the nova scam that one. No, not narrowbandimaging, that is a legit group it seems, so apologies to them, but your yahoo group narrowband. Of course since all that was pointed out on these forums you've had sense to go and shut that group down so the facts are hidden http://tech.groups.yahoo.com/group/narrowband/messages You can't shut down yahoo group vsx discussion though, and Hannah Varley and you have the same IP address on old posts on that, that is used same modem, and also on old aavso discussion posts there's you and one or two people who are you yet again, or maybe you're just so philanthropic you like to share your modem with people from all over the world, apparently including those who were currently in Oz or US the same day you posted. They must have very long arms. If you are so skilled, get your data together and make a JAAVSO submission and submit your new variables. Or wouldn't a former teacher, and IT teach as you claim, know how to report a report on a wordprocessor? It's harder than just freeform writing and whining on blogs and forums. |

John Greaves = advicegiven lacks the resources to make any
astronomical observations of his own and so he is reduced to shouting his paranoid delusions from the sidelines. Believe me, many of us have tried hard to deal calmly and rationally with his continuous outpouring of abuse, but now there is a higher priority than being polite: ensuring that his delusions are not accepted as truth. Not answering them incurs the risk that some readers may think that his points are unanswerable and that amateur astronomy actually rests on fragile foundations - just as Greaves pretends! The Greaves FAQ is nearing completion. Although in the first instance this was time-consuming to create it will pay for itself within a month or two (or even within a week or two). Nor is it as difficult to write as it may first appear because his current content is restricted to a fairly small number of fallacies. This means that any time a new posting appears it is not too difficult for a user to identify which answer is appropriate. Martin Nicholson Daventry, UK .. |
