Clavius, Plato, Tycho, Rima Hadley (Apollo 15), Copernicus, Gassendi and Vitello

Here are some of the images I managed to acquire last night before the seeing dropped off and the clouds came in. The main craters are:
  • Clavius, Plato, Tycho, Rima Hadley (Apollo 15), Copernicus, Plato, Gassendi and Vitello.
I was pleasantly surprised at how much detail came through as although the seeing had some good moments, characterised by the largest small craterlet in Plato popping out of the background soup for a split second at a time, it was mostly high frequency, jaggy seeing.

By capturing 10,000 Frames and then Aligning/Stacking the best 1,000 in Autostakkert!3, I was able to rescue some quite nice detail.

Tak Mewlon 210 F11.5 with TeleVue 2” PowerMate x2 and ASI 290 MM.

This put me at:
  • 4830mm FL at F23 and with the 2.9 micron Pixels of the ASI 290 MM, gave a multiplication factor of x8, versus the typically quoted x5 to x7 (F Ratio/Pixel Size).

Cheers
