Here's a series of three images of the region around Agatharchides P, an interesting crater on the shores of Mare Humorum with a complex rille system. I think the series illustrates that while you can do some very nice widefield lunar imaging with a smaller telescope, when it comes to high resolution imaging aperature really is king.
All three are taken with the DMK21, I took the first two on 22 September last year with my FLT132mm refractor, the third with the Mewlon 250 a couple of weeks ago. The first is taken with a TV 2x barlow, the second with a TV 5x barlow and the third with a TMB 1.8x barlow, so:
Thanks for that. A very nice comparison which illustrates your findings so very well. All I need do is sell the M180 and then save up for the M250! LOL!
