Hadley Rille

[StarSapling]

I very rarely have the opportunity to use the maximum effective magnification on my 90mm refractor. Last night was one of those opportunities, so I took advantage of it.

1/17/2016 - Oracle, Arizona - seeing good/excellent - trans fair - obs. good

90mm f10 refractor

Luna - 182x - Best view yet, by far, of the southern portion of Hadley Rille - appeared as a definite arc from its southern source out to the west and back into the shadow of the mountains - I even imagined that I caught occasional hints of the northern portion of the rille!

Nice going starsapling. Hadley Rille is something I've not seen yet, must give it another go soon

That part of the Moon is one of my favourites to explore with a scope

It's fun to trace the Hadley Rille as it snakes around the Apennine range. It's possible to see the sections visited by the Apollo 15 astronauts where there is a sharp "elbow" in the Rille.

The rille is looking rather fine tonight as well, as it happens

I'm trying to spot the one that runs down the Alpine Valley now. That ones a wee bit tougher !

Me too John. When the terminator permits, it's the first target I go for. I always think back to the Apollo 15 images of this immense groove snaking across the moon's surface and the mountain in the background. Brings lunar astronomy to life.
