Whenever I have come into large sums of money in my life, I always put half of it aside to spend on fast cars and the pursuit of loose women.
I put aside the other half to spend frivolously.

Planetary astronomy and imaging
Quote:With comparison with the 610 filter which quantified gain the 685 is bringing?
This is interresting to know.
Do we have the idea of which absorption band is involved for the contribution of the image contrast, we have the 619nm (stopped by the 685), the 889nm and after with regards to the chipset sensitivity?
Quote: For those who are doubting a lot
Quote: The R610 does indeed appear to show atleast a thread of a lighter colored zone by the pole. The other is a little too ambiguous .
Quote:Christophe it's time to change
Quote:For imaging we had J Sussenbach who succeed too but not as clear than Fisac, we have others (russians among them).At present there is D.Peach who performed the best Uranus image with his 355mm but in near NIR, clearer than the 1m.
