Description

Took advantage of some rather good seeing (a firm 2 on the Antoniadi scale) to image this evergreen that can always reveal some new detail if things work properly.
This time I used a Fringe Killer filter instead of an IR CUT one with my C6,  reckoning that it cuts off on one end of the spectrum some violet-blue light which is the most sensistive to seeing, and on the other end everthing from deep red to IR, which should in theory increase effective resolution by taking off longer wavelengths.
So this is a sort of compromise between resolution and sesitivity to seeing in term of wavelength filtering, but a compromise which should also privilege the green wavelength for which the 178MM camera reaches its peak sensitivity.
