Super-Sized Moon: Full Camera Resolution
Check out the Nikon D810A Moon pictures here. My primary Moon picture page is here.
More Moon Pictures from 1/1/2009 are here.
I tried some DSLR moon photography at the end of a lunar observing session 1/19/2007, assisted by Bill F. "VALLIS SCHROTER" was well seen, as shown in the right-most image. Dennis B. from the FBAC notes: Ah! You just missed getting Wargentin but the Sun wasn't up high enough yet on the Moon! Phocylides, Nasmyth, and Schickard are obvious, so if you has imaged a couple of hours later, Wargentin may have just had a bit of sun light. (The large crater on the top of the middle image is Schickard, with Nasymth right below, and Phocylides and below that. Wargentin is just to the left of all that!)
The Virtual Moon Atlas provides the following data on Vallis Schroter:
Size:
Dimension: 165x165Km / 97x6Mi
Height: 1000m / 3000ft
Height/Wide ratio: 0.0063
Description:
Remarkable rille. Directs to the North then turn to the West. Width varying
6 to 10 km. decreasing to 500 m to its West extremity.
Begins to 25 km to the North of Herodotus by a lengthened craterlet called
'the Head of Cobra'. Floor covered by a 200 m wide rille.
Seeing was pretty good and I was able to get a decent focus I think. The moon was pretty much straight overhead at 10:16 when this image was made. (Straight overhead means crawling around on the deck to check your framing...) The above is a combination of 3 sections of a single exposure, 1/160s at ISO 800. Canon EOS 20Da (unmodified), Takahashi TOA 130 (a 5" APO refractor) with 1.6x extender, and Astro-Physics AP 900GTO mount.

2/25/2007 at 7:52 p.m. central time. The crater Eratosthenes sits at the bottom of the mountain range Montes Apenninus bordering Sinus Aestuum, atop Mare Imbrium in this shot. The large crater to the left of the mountains is Archimedes, and the crater to the upper left is Plato. Lunar Phase Pro tells me that the moon was 68.2% full, aged 8 days 8 hours at the time.
2nd Place.... Again!
Always a bride's maid, never a bride: This image took "runner-up" in the Yahoo digital_astro group's March "High Resolution Moon Image" contest. I believe that's the 3rd time I've taken 2nd place!
As I take a fresh look at this image I'm seeing some thing's that I think I can do to improve the processing, but it's "not bad."
Takahashi TOA 130 (a 5" APO refractor) with 1.6 extender at 1600 mm, f12.3, 1/15s on the Canon EOS D20a at ISO 100 setting.
Below: More moon shots from 10/2007 with same setup as above.
Here are some grab shots of the moon the 10/2007 while shooting Comet Holmes (17P/Holmes). Langrenus is the prominent crater upper left. More info on Petavius is here.
That's about as much as I could fit on the frame using my TOA 130, 1.6 extender, and Canon 20DA.
