Cedar Point Amusement Park from 25 miles away: (200% crop, taken w/ 105mm lens)

Down by Lake Erie today: I was watching through the viewfinder and focusing as I ran towards the flock- this is a wide angle lens, objects are much closer than they appear!

Magmatic-intrusive-breccia/explosion breccia intruding into country rock, Fen complex. Similar to Fen 266, the breccia is matrix supported. Most of the clasts are individual fragments of either quartz or feldspar and likely originate from splintering of adjacent country rock (Telemark gneiss)...

When the writing/script ties itself in knots trying to create a reality-based explanation for fanciful technology. Current offender: "Dark Matter". Could not force myself to watch past episode 4.

Last week was completely cloudless and low humidity- unheard of! Here's a sequence of the moon: Here's a few close-ups (400%, no interpolation) of (imo) interesting features: Alphonsus, in the center, with a low ridge, like a wrinkle. North pole region Gassendi I've made...

Here's version #3, courtesy of Big Bird:

Strongly fenitized gneiss, Fen Complex. On the left side: large grains of chessboard albite. Chlorite is light green in PP and either low order or anomalous brown in XP (in contrast to Fen 282 ii). In places, anhedral grains of cancrinite (clear in PP, low relief, and 3rd order...

I really like Fig. 15- very dynamic image and the sky looks amazing! Did you have a polarizer on the lens?

Strongly fenitized gneiss, Fen Complex. Sample primarily consists of dusty K-feldspar, chessboard albite, and chlorite. Chlorite is olive green in PP and either low order or anomalous “Berlin blue” in XP. Abundant pyrite, Ilmenite and titanite/leucoxene. The titanium oxides...

Catching up with the backlog... Currently my GM-8 mount is under repair- the quadrennial replacement of the declination gearbox- this is as much time on target (18 hours total) as I could get before the gearbox completely failed: This is the full frame- the prominent galaxy is NGC 7331...

I couldn't see the moon this morning- I don't have a clear sightline to the horizon and the moon is too close to the sun (new moon). Last night was (supposedly) peak Draconid meteor shower, so I tried imaging (using a non-motorized tripod) with my now trusty Vivitar 28/2.5 lens. I realized...

This morning was also clear: Nikon Z7 + 800mm lens, 0.5s ISO 800. Lower ISO = less noise = :) ISO 64, 1/20s exposure. At 200%, along the border of Oceanus Procellarum: Prominent craters from lower right: Grimaldi, Hevelius, Cavalerius (located approximately in the image center).

Melteigite (Ijolite) intrusion adjacent to fenitized country rock (telemark gneiss), Fen complex. The intrusion consists predominately of a dense mat of anhedral augite prisms, some zoned, with abundant euhedral titanite (sphene) and fine-grained mixtures of muscovite and (likely) aegirine...

Thanks again! Another significant advantage of using 'live view' is ease of focusing- once upon a time I shot a roll of Ilford SFX Infrared and had to adjust focus to account for chromatic aberration. Because (at the time) there is nothing to see and focus on through the viewfinder, the lens...
