Geminids 2020

[James K]

I've been watching the approaching weather as well (honestly its progressing about as I expected with more snow/cloud/cold for the weekend than early forecasts were showing)

Last night I did go out briefly to see if there was any chance of seeing northern lights. Same as John Farley - fail, but in this case because there was a patch of cloudiness north of me....but pretty sure the glow from the city lights in that direction would have obliterated anything even if it had been there? Zero chance of seeing anything tonight as its fully cloudy(no snow yet).

Not looking promising.

Seeing clouds clearing late evening after the snow yesterday, I zoomed out to far eastern Arapahoe County, settling a mile or two south of U.S. 36 northeast of Deer Trail. It was creepy enough being out there after a fresh snow; not only was it cold as balls, but there was spotty freezing fog competing with the occasional cloud decks east of Denver, and I oftentimes could not discern sky from ground where I was, so I wasn't always sure what I was looking at. Somehow I managed to get about an hour or so of nearly pristine clear skies with little fog, but a nearby power line was almost constantly snapping and buzzing behind me.

I saw probably 30 or so Geminids in around an hour, and I was impressed by their angular coverage in the sky -- I saw them in all quadrants except straight west. They also literally seemed to be radiating from Gemini, which, even though that's how most meteor showers work and get their name, I almost never can discern from what I see. Not the case here. What did not impress me was the lack of bigger/brighter ones. Some of them I could barely see even when looking right at them in the rural darkness.

Even though I had my shutter open and pointed in the direction of several that I could see with my feeble human eyes, I found very few showed up in my shots. Not sure what is going on here...as they looked plenty bright to me, but they show up quite dim from a Nikon D750, which seems at odds with what I see in others' photos. Are those other photos enhanced in some special way? Are they fireballs instead?

This one (left center) looked quite big to me at the time, but looks pathetic on camera:


Ultimately I had as good a time photographing wintertime constellations as I did seeing meteors. After about 60 minutes in the 10 F cold, (even with apparel and taking 5-10 minute breaks in my car pumping the heat) I had had enough by 12:30 or so, especially as a fresh cloud bank started encroaching from the east.


I may try again tomorrow to catch the peak night in the hopes of more activity. However, the cloud cover situation in NE CO continues to look iffy. Might have to hope for a break in the cloud streets as the most recent CAM forecasts are indicating.

Thin cloud layer has settled in. Saw a couple before. Will try again shortly. This doesn't surprise me.

I looked out just a bit ago. Some scattered clouds in my area, but its what I'd term as mostly clear (in that respect it'd be a fairly decent night).
Too bad looking through a window wouldn't work .lol. its too cold for me out there in the yard where I'd have a little better view. (but that said, I'm just too tired to stay up much later anyway...)

Jeff, that snowy road nightscape is beautiful! How long were the meteor exposures? I try to stay around 4-8 seconds to let the meteor own more brightness vs. surrounding sky & crank ISO somewhat obscenely to compensate. You may be doing similar, but I'm not familiar with D750. Looks like you have great sky conditions there. I noted similar to you that these were mostly pretty faint, at least compared to decent Perseids.

The cloud threat in northern Arizona for Sunday night/Monday morning looked really bad, so I made a run on it Saturday night/Monday morning. This image includes 68 Geminids and 10 sporadic/other meteors from midnight to 2AM, just west of Sunset Crater looking across Bonito Park. Tons of airglow on the left, Flagstaff light dome on the right and some Winter Milky Way to split them up.

Image is a stacked composite of 86 frames: 10 to reduce sky noise via Starry Landscape Stacker, & 76 of individual/paired meteors derotated and carefully re-aligned to the star field through which each one passed. Canon 6D Mark II Tokina AT-X 16-28 f/2.8 @ 16mm 86 x 6 sec., f/2.8, ISO 12,800.

Thank you for the compliment and comments. I was shooting with medium ISOs...5000-8000 for most of the time, although later in the shoot I decided to drop down to 3000 or below to get more star trails in. Do you use high-ISO noise reduction? I have tried it before, but I found it doesn't seem to improve much on my camera unless I'm at ridiculously high ISOs, like 12000+, and even then it almost seems to create noise on a different scale to compensate for what it removes (as in, the pictures start to have a look as if they are highly compressed JPGs or just look unnatural). Regardless, it looks like the Geminids in my shots aren't too terribly different looking from what you have, so it may just be that Geminids are on the fainter side.

I tried shooting Perseids from Berthoud Pass (>11,000 ft) back in August, but the developing wildfires in W CO and some sporadic clouds made that night of shooting less than rewarding. Some that I did see looked brighter, though.

I haven't tried anything in-camera for noise reduction. I'd probably find it doing annoying things like you noted. Noise is definitely heavy at ISO 12,800 on the 6D Mark II, but it's natural & even and responds well to stacking or post-processing noise reduction.
