Nah that's pretty good Mike, when did you take it, I don't recall you posting it..?
Hard to make a critical comparison because that is a small file you have posted and hard sharpening not withstanding, the general spacial resolution within the details looks pretty similar to mine. To get closer to Chart 32 we need to move our gear to Freeling Heights in the Flinders Ranges..... at least! It's only a modest 859m ASL but a critical testing regime, showed seeing was slightly better than Siding Spring
....of course sharing a scope at any of the observatory mountain sites in Chile would be better though
