Clear glass modded T1i w/ cls filter, w/the ED80 @ native, will have to check back on the details, yet do believe I used data from 2015 as well as last month. The RGB was the best 80% of the stack. Might be around about 8 hrs total. Did an "L" layer, so, once agin it's an LLRGB. Fairly pleased w/the result, as part of the "triangle" is visable. Next attempt(s) will be w/ the .8 FR to get a bit wider field.
