152mm A+M Refractor(OfficinaStellare-1200mmF/L) using a CanonEOSII RebelT7i modifiedUV-IR @ Hutech , using a BreakThrough X4-UV 49mm filter with step-rings from 48mm and a TeleVue 4XPowerMate into a TeleVue 2XPowerMate for an effect of 9360mmFL on an Astro-Physics 1200GTO Mount . I did 'one-shotColor' images after 'focusing on and imaging the Cat's Eye Nebula NGC6543 with 30secISO12800 in MaximDL Pro V6.20 to focus the Cat's Eye as RAWMonochrome and 'screen-stretch' at 'Planet' which showed the star by the nebula to get it at it's smallest size and the 'center' star in M57 showed a brightness also . I dis-connected the RebelT7i and I did the 'one-shotColor' images with the TC80-N3 Timer . Two 100secISO6400 images and two 100secISO12800 images and two 150secISO12800 images and two 181secISO12800 images and four 213secISO12800 images ... at 150secISO12800 the nebula had a noticable brightness increase and more exposure time showed more stars in the background ... M57 was at the same focus position as the Cat's Eye Nebula ...I did a "BatchProcess" to the twelve CR2.s and I Sum stacked them and I put the 'screen-stretch' to MaxVal and then I 'opened' the "Digital Development" command and at 'Kernal-Low-Pass' I 'unchecked' the 'Auto' box for 'Mid-level'' and then I left-clicked on the brightest part of M57 and it had less brightness than the 'Auto' box did .. then I did the same for 'Background' using the 'mouse' also and the 'background' was darker . ..... other commands were used like "Adjust Saturation" and "Kernal Filter" and "Deconvolve" . ?!. The FITS will "PinPoint Astrometry" USNO-A2 solve . The Moon was high in the sky early morning March 16 , 2020 when I imaged M57 to see what I could get . x
