Re: Image.Rectangle Crop

Thank's Fabio The goal is to crop in etc 3:2 format. As I understand the crop as it is, I'll have to do the calc. every time. The macro is for simulate crop as we know it in PS or Gimp. Make a selection with giving aspect ration. @Iver that way will only make the same crop every time. Same as the Im...

Hi' AA's (Nothing about Alcoholic) Trying to make it easy to crop to a known aspect ratio. I can make a crop by the Image.crop (x1,y1,x2,y2) But that's very "hard coded" (Inflexible) Then we have the Image.Rectangle but as I read it, it's only for returning size, not for setting. I want a macro to a...

Re: Sky Background

Ahh, thank you Rudi. Then it would not be possible to convert to Bortle I give. Bortle is for the eye, ADU for the camera, Gain etc. But the picture background are dark, and ADU 2100 is pretty dark :mrgreen: The curve shows me the sky getting darker as times goes by. Right until someone hits the lig...

Re: Sky Background

Thank's If I only gain 0.45% SNR then I didn't hat to stack them at all. And if I fiddle with the filenames it will come out with another table as you see. It's seems AA has it's one filename sorting. Expecting a numeric value in the file name. Report_Pacman_Reverse.JPG So I still want to know, what...

Re: Sigma + sum

Thanks again Iver Yes that was what I found in the manual. Nothing about sigma+sum. I am using dithering so my gees is the best is sigma. Remove hot pix and trails. Sum as I think about it should increase SNR. But it says for 8bit files. I think my cr2 files are 16bit. My result with sigma + sum are...
