Re: Deconvolution Fade

Hi, the visualization is different: V = 930 - 65535 in the first image and V = 930 - 118200 in the second image. This could be related to the highlighted star, which was saturated, so during the deconvolution the peak went from 65535 to 118200. It's possible to press CTRL + E to bring both images to...

Re: Demosaic - extracting green channels

In binning 2x2 (option "Green channel 2x2") they are averaged, and it can be proven this way: using the Edit Pixel window set one of the pixels to 1'000'000 and the resulting pixel will have a value of approx 500'000 (disable temporarily the option Hot Pixels in Demosaic)

Re: Automating stacking and reduction in sets of 5 images

Hi, it can be done with a script, calling the Preprocessing function for every mini-set of 5 images. I can show an example, what is the name of the sequence files? Is this for an animation? (so 60 frames composed of 5 images each?)

Re: Processing Seestar S50 images

Are these RAW files similar to those produced by DSLRs? If yes, you may use the same workflow. Feel free to send me a sample image for a better advice.
This little device seems really nice, I would like to have the time to use one. Since it's altazimuthal, does it include a derotator too?

Re: Processing Seestar S50 images

Hi Andrew, I see that it can produce FITS files, are these already demosaiced, or just RAW?

Re: Plate solving parameters in Telescope control Centering

Hi, the plate solving engine cannot be used to send positions to the MPC, it's too risky since the precision will be unknown. It's designed only for speed and reliability, so only for telescope centering. Once the image is plate solved, the procedure is: 1) Click the Atlas icon to center the Star At...

Processing DSLR images in JPEG mode

Hello, I was asked what are the best settings to stack astronomical JPEG images from DSLRs. Well, since the images are 8 bit, there are just two good options: SUM and SIGMA+SUM. Today I received the following result image: Sigma+Sum stacking of 14 images, 120 seconds each exposure, 4 dark frames (ev...
