13998380 - The morning Zodiacal Light (the subtle glow rising from the left up to top centre) with Venus as a morning star just below the Light.13829449 - A beadlet anemone with reflection on the underside of the sea with clouds and subtle sunset in the background. St Abbs, Scotland.13900221 - A subtle and pastel aurora borealis (Northern Lights) in the northeast, above a prairie meadow at "Lone Tree Hill". The foreground and sky are lit by a bright waxing gibbous Moon, a day before Full, shining in the south. This was just after midnight on July 11/12, 2022. The auroral curtains exhibit the usual green band and rays, though with shades of green visible, perhaps from hydrogen-beta proton emission as well as oxygen electron emission, but also upper altitude reds and purples and a faint blue tint at the very tops where the aurora is lit by the Sun. The aurora was never bright this nig13899071 - This is a portrait of the main nebulosity in Orion in his Sword, including: the Orion Nebula itself (at centre), aka Messiers 42 and 43, and the Running Man Nebula above (aka NGC 1973-5-7). The bright blue star cluster NGC 1981 shines above the Running Man. The subtle reflection nebula NGC 1999 is below M42 but a bit lost amid the other faint and dusty nebulosity.13897565 - A 360° fish-eye view of a sky-filling aurora on March 4, 2022 taken from the Churchill Northern Studies Centre, Churchill, Manitoba. This is looking north but with the lens taking in most of the sky including the zenith at top where the curtains are converging and swirling, and near the Big Dipper. Note the subtle nitrogen pink fringe along the lower curtain.13999638 - This is a roughly 150° panorama of the sunset sky at Sunset Point,Bryce Canyon,Utah,taken as the last light of the Sun was illuminating the distant buttes. The sky has subtle dark rays converging to the anti-solar point,the point opposite the Sun. These are anti-crepuscular rays – shadows cast by clouds in this case,such as the one at left.13998491 - This is the rich star cluster nicknamed Caroline's Rose,or officially NGC 7789,in Cassiopeia. Caroline Herschel,sister of William Herschel,discovered it in 1783. In the eyepiece its stars do take on the appearance of nested rose petals. Subtle effects like that are always lost in photos of star clusters.13898215 - The well-known Double Cluster (aka NGC 884 and NGC 869) framed at upper right to include two of its companion star clusters, NGC 957 at upper left and Trumpler 2 at lower left. Dotted through the field of young blue stars are numerous aging yellow giant stars. And the gradation in sky colour from the clearer, bluer sky with more stars at right to the dustier, yellower sky and fewer stars at left is subtle but obvious here, from interstellar dust in this part of the Milky Way.13898108 - The appearance of the infamous STEVE glowing arc south of the main auroral curtains, on May 27-28, 2022 from home in southern Alberta. This was early on about 11:53 pm MDT as STEVE appeared in his classic mauve colour in the east. STEVE = Strong Thermal Emission Velocity Enhancement, created by hot gas flowing east to west south of the main aurora during an active display. It was Kp5 this night. The main aurora has some subtle blue rays within it at left.13829445 - A bouquet of plumose anemones (metridium senile) in the phytoplankton rich waters of western Scotland with subtle sunlight breaking through the surface71410831 - Europe, Southwest Iceland, Skaftafell National Park, Vatnajokull Glacier.
