All detailed. Time for some starlight! (hopefully the wind will stop blowing)

Starting to have some fun with the scope. Seeing was good enough (darn high clouds) to allow me to see the central rille in the Alpine Valley on the moon. I was also able to see minor craterletts scattered across the floor of the crater Archimedes before the high clouds ended my observing session. The three primary craterletts were also well seen.

If the seeing is good enough I will do some critical ronchi and star testing. According to "netblue" the seeing should be decent.

Will go for some of my other favorite lunar targets tonight (Plato crater counting, PI Kies lunar dome pit, etc.). Hopfully I will have less high clouds than last night.

Keith, if you were able to see the rille in the Alpine Valley, that's quite an accomplishment, IMO.

Hi Darian,

Thanks. I tend to push the limits of an instrument to see how good the optics are. When I saw the rille I was quite surprised. I went to my cooled C-14 to confirm that the seeing was in fact good enough to reveal this feature. It was. Last night I was able to see the Pi Kies lunar dome pit and counted the 5 main craterlettes on the floor of Plato. The seeing wouldn't allow much more high res detail to be seen. My 250lpi etched glass Ronchi, at two bands revealed 2 straight bands inside of focus and a clean edge. Ths startest was also good. It looks like Coulter's claim of a 1/8th wave wavefront was true, at least with this optic set. And the testing continues...

Well... all my "winter" projects are completed! Time to hunt down some high res targets with my Po' Boy refractor, Coulter cass, and C-14 grin
