Thanks Stuart, Gary, Rodney and Scott
Stuart: I really do not know the cause of the
spikes, perhaps they could be due to the clear filter I use to seal the
camera
Rodney: Indeed M45 was a dificult object (three
tries) due to its low elevation (taken last august) and the response of hypered
TP to the scattered light. Thanks for your kind words
Scott: Yes, only two targets per night at f/10, but
I like the resolution I get at 3.5 m focal lenght. The bands you observe are due
to the processing applied to remove some uneven density on the
negative
