The largest volcano in the Solar System and the largest mountain in the Solar System are one in the same: Olympus Mons on Mars. Olympus Mons is a shield volcano that towers to an amazing 26 km. That makes it 3 times the height of Mt. Everest.
Yosemite never fails to amaze 😍

N I G H T S C A P E R • Photo Award to ...
SINGLE EXPOSURES: Frosted Leaf Galaxy > Dandelion galaxy > Milky Way Lilium japonicum (SWIPE left to see all 3). Which one do you like best? Congratulations to Masahiro Miyasaka. YES, these are all single exposures! Read the TECHNIQUE below to learn how to get this much DOF in only one exposure.
MORE from Royce: I first discovered Masahiro’s amazing work back in 2010 when this leaf photo appeared on the @nasa_apod for 2010 Nov 17.
TECHNIQUE & EXIF: Single exposure • Canon 5D MarkII • SIGMA 15mm F2.8 EX DG FISHEYE • ISO 4000, F/2.8, 30 sec for sky (using Bulb mode and infinity focus), keep shutter open and quickly cover lens with lens cap, change aperture to f/22, uncap lens and give additional exposure (about 18 sec) for foreground lit by LED, close shutter.
This technique is detailed further (using an electronic flash to light the foreground) on page 111 in my @MilkyWay_NightScapes eBook. To get both the sky and the closeup object in focus (with longer focal length lenses), you will need to focus twice—all during one exposure. Here’s the complete procedure:
1. Prefocus for your closeup object and mark it on the lens barrel, then return to your preset infinity mark.
2. Set up your strobe above your foreground subject and predetermine your exposure (i.e. using a manual, 1/32 power for f/16 @ ISO 6400).
3. Using “bulb” mode, open shutter and expose for sky (i.e. f/2.8, 25 seconds, for ISO 6400).
4. With the shutter still open, place the lens cap on the lens, at the end of the night sky exposure (i.e. at the end of 25 seconds). Instead of a lens cap, you can put a black lens bag over the front half of the lens.
5. You can now use a dim flashlight to change focus for the closeup object (rotate to preset closeup focus mark), and change to the predetermined strobe aperture (i.e. f/16). Shut off your flashlight.
6. Take off lens cap or black bag and fire strobe (I use a radio trigger for the strobe).
7. Close the shutter. You’ve now done a two-stage focus stack, all in one exposure!

Stargazing in Manzanilla
Dark skies and star gazing missions to Manzanilla/Mayaro can never get old. Here we have the milkyway and a tropical backdrop of coconut trees and cloudy caribbean skies.
Remembering my most interesting astro photography mission for 2018 as one of my landscape photography brethrens @jason.fineart and I ventured amidst cloudy conditions to try our luck. It turned out pretty ok and made it worthwhile given the hindrances

💬 “I turn and see the silent, contemplative, spiritual moon shedding the softest imaginable light on the western slopes, as if, after a thousand years of polishing, their surfaces were just beginning to be bright; a pale whitish lustre. Already the crickets chirp to the moon a different strain, and the night wind blows, rustling the leaves, from where? what gave it birth?”
