Box Nebula NGC6309 Canon Rebel T7i 188xpwr magn. ... sixRAWMonoAutosaves thru MaxomDL Pro V6.16 and processed to this image . I Sum stacked them and tried a lot of commands .. "Histogram Stretch" two different times and "Kernal Filter-Dilation a few times" .. I don't know if there is evidence of stars in the nebula but a few places looks like there is .... I don't know if there is any resemblance to the real nebula . The FITS must be "Double Size" to get it to 'solve' as USNO-A2 .x
