    152mm A+M Refractor(OfficinaStellare-1200mmF/L) thru a TeleVue 2.5XPowerMate for an effect of 2960mmFL using a CanonEOSII RebelT7i modified UV-IR @ Hutech and using a BreakThrough X4-UV 49mm filter with step-rings to 48mm doing RAWMonochrome Autosave images thru MaximDL Pro V6.16 form 47secISO1600 to ISO12800 and the same for 81sec and 120sec , and 181secISO25600 then included . Some of the 'objects' I have been doing have had to have a 20sec'guiding' star exposure with an ZWOASI120MC-S webcam at Bin2 because there are very few stars looking West to 'guide' with , but I had the PEM-ON in the Astro-Physics 1200GTO Mount which might help to keep the 'tracking' steady . I used RAWMonochrome Autosave Sequences for 47sec , 81sec , 127sec , and 181sec . There was some dis-coloration in the background but "Flatten Background" with alot of points helped , and "Color Balance" where I used the M106 Galaxy core with the 'mouse' for 'Background' and that darkened a lot in the 'background' removing dis-coloration . x
