RebelT7i modified by Hutech using a'TPO 80A lightblue 2in. filter' thru a TeleVue 2XPowerMate for 2980mmF/L thru a 152mm A+M Refractor(OfficinaStellare) for four CR2.s 187secISO6400 and Average stacked on an Astro-Physics 1200GTO Mount with MaximDL Pro 3secGuiding with an SG-4 and after stacking I put the FITS into "ImagesPlus" to work on it . Eventually I used the 'Multi-Flatten Background with 'normalize' to 512 instead of 5120 and the background darkened by removing the pale light-shade around the galaxy .I was quickly doing different galaxies so if time was taken with a better 'focus' and better guiding with more images taken it might make a good image . The image isn't cropped and M66 is at this large size .x
