Is binning percent linear with resolution? For example, Let’s say you’re shooting with a resolution of 0.5”/pixel and you think 1.5”-2.0”:pixel is more reasonable. Would you bin at 25% to 33%? Or maybe a little less (50%) to allow for deconvoltion?

Thanks, Wayne

Thanks Ivo, sounds great. I’ve ordered the “early bird” model of the new QHY sCMOS OSC cameras, the QHY268C, with Sony IMX571 BSI APS-C sensor. Super sensitive, 16-bit ADC, very clean, no amp glow. Can hardly wait to try it! Now it sounds like the process you describe would be great for narrowband t...

Hi Ivo and fellow ST users. What is the best way to process OSC data taken with one of these new multiband filters (Ha, O3,S2 for example). In the documentation, it’s recommended to take L data through the filter and then RGB data without it. What’s unclear is if that applies to DSLR or other OSC da...

Thanks, your insight into what is happening is appreciated. The camera currently doesn’t allow user-selectable gain. They have predefined low-gain and high-gain settings, you can choose one or the other or a merge. The merge crossover is 3800 ADU (on a 12-bit 4096 Max scale). I’ve been using the hig...

Interesting. The post you linked was by Tolga Gumusayak, one of the foremost users of the Kepler 4040. The way the camera is supposed to work is simultaneously take a low and a high gain image and merge them to get a quasi HDR image. In this way it would keep the merged image in the linear range I s...

Here is a link to the final integrated Ha and O3 stacks and the TIFF of the processed image up to color calibration. These consist of 68 3-minute Ha and 67 3-minute O3 images taken with an FLI Kepler KL4040 Scientific CMOS camera at high gain calibrated with matching darks and flats. This cameras im...

I’m having trouble getting almost any color in the Duoband process of my HOO Veil. When I first open the module and the settings are Scientific Color and the Identity (Off) Matrix settings, colors are almost neon bright red and blue/teal. However when I try to go to Artistic or change the Matrix to ...

Yes perfect sense. Thanks

Yes Entropy module! Thanks!

Thanks! If I do use the APP synthetic luminance, which is a luminance extract of a stack of all the R, G and B subs, what exposure time do you suggest? For example I have 90 minutes of Ha and O3 and 170 minutes of S2. 350 total minutes? Or is it smarter to divide 350 by 3 to get an average duration ...
