Aperature and Lunar Imaging

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:

1. FLT132 at 1850mm FL

2. FLT132 at 4625mm FL

3. Mewlon 250 at 5400mm FL
