And yeah - it's a little close to the house, so North sky is a bit obscured.
Given the level of light pollution here in the Northeast Corner of Indianapolis, it really doesn't matter that much.

Secondly -
Crescent moon, exposed for the Earthshine side. Minolta X-700, Tamron 300mm/f2.8 - wide open - let the computer decide on shutter speed.
Other details, same as previous pic.

Another Moon -
This one is trickier. Kiev medium format lens - 300/f4.5. Plus 2x teleconverter. Add Kiev-to-Minolta adaptor - and then add Minolta 2x converter. My math tells me that's approximately a 1200mm f18 lens. On the SRT-202 body, @ 1/250th sec.
I wasn't quite sure if this massive combo was actually going to reach infinity focus, but it looks like it did.
Same Fujicolor 100 print film.

One final -
Sunsets count, right? I mean, it's a pic of a star, huh? 8)
Minolta X-700, Tamron 300mm/f2.8 - stopped down to (I think) 5.6. Again, computer picked appropriate shutter speed. It was either 1/500, or 1/1000. Hand-braced on monopod.
Still back in May sometime, and that same Fujicolor 100 print film.

Oh, My! And just what are you asking for your surplus 20D, Jeff? 
Just out of curiosity?
-Kevin, who's been wanting one.

Hi All,
If I divide a CFM value by 60 to get a cubic feet per second value it looks like I'll need Pratt & Whitney Double Wasp radial engine to drive a fan at the necessary rate
The upside of that is it would just sound SOOOO awesome. *evil grin* There ain't much that sounds as good as a big round motor.

Reprocessed M101Posted By Kevin Vernon |
What do I think? I think I wish I had a decent mount. 8) I think I wish
I had skies that could be called even remotely dark. I think I wish I knew how
to do that.
I think it's absolutely gorgeous, Tyler.
