Colors! Now we're talking! Can you do one with 8x10 color glossy photographs, with circles and arrows and a paragraph on the back of each one?

I think 16-bit ADCs are now fairly common, with the IMX571 having become so popular, though maybe that's...

I was also able to "hide" it by increasing Optidev's curve resolution (the amount of points it calculates to interpolate the constructed curve between) 16-fold (from 4096/12-bit points to 65536-bit points), which should not be necessary unless something has stuffed lots of data/"detail" in a tiny (...

What Mike said - thank you, Ivo! Haven't had time to do much beyond download the new beta yet, but a quick look seems similar to Mike's reaction. Different, but definitely improves (cures, even?) the dark-ring effect. As for 16/32, it's a bit awkward in Siril to keep swapping back and forth (really,...

The plateauing can be caused by a number of things and would - as already mentioned - be chiefly caused by an area that shows comparatively very little change in co-located pixels (as a proxy for "detail"). It would therefore receive a smaller dynamic range allocation. I've seen this happen as a re...

Yes, it seems only two distinct values are assigned to the core regions of bright stars. The max value to the 'inner core' and then just one slightly lower value out for a distance surrounding it. It feels weird to realize how much time I've spent chasing an optical illusion (usually with fuzz in SV...

Last night was clear but very moony, so I just shot a few hours of M3 with the AT130EDT+IMX571c. I stacked about half of the subs, which all had FWHM at or better than 2.3" - 220x45s Low-Conversion Gain (gain 0 to you ZWO folks). The brightest star in the frame is mag 6 (which is possibly related to...

If I work another 30 years I could stop with the whole "retirement savings" thing all together and just blow it all on astro gear! Brilliant!
