M45 from last month but I used seven CR2.s as 140secISO1600 for four shots and three 200secISO1600 with a Canon EOS Rebel T7i 'modified by Hutech' using a Baader UV-IR Cut-Off 2in. filter with a TeleVue .8XReducer/Flattener thru a 152mm A+M Refractor(OfficinaStellare) as 950mmF/L . I put the CR2.s into "ImagesPLus" and used SigmaClipAverage and did everything there , including 'Feature Mask' , and after that the 'Frequency Spectrum' command for 'Blur' to smooth the image better . The idea here is to try to see if 'brown dwarfs' are visible because Wikipedia on the M45 says they are in the Pleiades area . The FITS is from "ImagesPlus" to MaximDL Pro V6.16 where I only used "Pixel Math" and "Resize" from 3.72micron pixels to 6.5micron pixels and then "HalfSize" …. and it "PinPoint Astrometry" 'solves' with the USNO-A2 from 6th to 18.50 for magnitude using 300 stars for the 'solve' , and there is a 20th magnitude star in the 'center' darker area .x
