Hello all,
I've been watchin this forum and your perfectly detailed images! But now, I finally had some clear skies. So I captured Mars, after long time of cloudy nights ... Seeing was just average, so I push the QHY5 mono to the limit and set gain to 100% (very noisy :() and exposure set to 10ms. For my surprise, some more details on surface was appear (in compare with 80% gain and 33ms exposure). For color information I used visual green filter + UV/IR cut filter, as a green channel and 760nm IR filter as a red channel. The blue channel was synthetized. Finally I used an IR channel aslo as a luminance, so here you can see an IRIRG(sB) color composite. Used 8" Newton and 8mm TeleVue Plossl.
Cheers, Roman
