Dropping by again to comment on Hygge’s post, but let me tell you, those iridescence and corona pictures that I see when I go back are killing me, I love them to death. How do you manage to get them?
Now back to the sycamore tree picture. That is Owen Hymphreys’ shot. Incredible shot. He is in that zone far enough north where the occasional aurora is distant so you mainly see the high part, which tends to be red. He has others, as well as sunsets, sunrises. They are mixed in with his regular jobs pictures:

I love this moon picture, Ruth. Beautiful framing and colors.
Night sky pictures is one think I really enjoy doing. A couple of weeks ago I traveled to Arizona to shoot the lunar eclipse. I’d like to share the video I made from the shots:
That was on a full moon to, but it entered the Earth shadow, so its brightness was greatly reduced. The result was that one could see all the stars as on a new moon night while also seeing the “blood” moon. Beautiful experience.
Thanks, everybody.
Iridescence is so hard to capture, which makes these shots really exceptional. I am seriously envious.
And this is the second one:
Jupiter and Saturn flank the moon and together they glide to the west. Venus is shortly visible by the flag pole. Some stars of the teapot asterism are also noticeable. Serendipitous high clouds generated a rare brightly colored “moon dog” or parselene and a nice partial corona.
I have not visited this thread in a while and I see some incredible shots, Keelin, Ruth, Hans! Those “ripples”, Ruth, are CAS calendar material, I hope Gavin notices them.
I wanted to share a couple of short videos I made with the intention of capturing the stars, the moon, planets at night. Serendipitously, I also caught some optical effects. Here is the first one. Best watched on a big screen with sound on.
I wanted to see if the Milky Way was visible in this dark place, but the moon, even at 35% was too bright. Instead I was treated with a “moon dog” (a parselene), rather diffuse, but clearly visible, and a moon pillar as the moon set. Not to mention some great cloud movements caught with a second camera with a very wide angle lens.
I agree with Hans on both. I also wanted to add that IR makes the sky darker, actually very dark. That’s because the blue light, which is scattered by the air and gives the sky its luminosity, if cut out by the filter IR filter. So that results in greater contrast.
Jumping in a little late … The wavy clouds on February 2 are stratocumulus undulatus. But what makes them so cool is that above them you have a layer of altostratus of a different shade of gray.
The “tornado” is indeed, like Greg says, a contrail twisted out of shape by winds with different directions and speeds a different altitudes and even within the same layer.
Funny! Like a big fish in the sky.
Which reminds me I also saw a fish in the sky, not sure if I posted it on CAS.
Thank you Keelin! Your picture reminds me of a stormy ocean seen from an airplane, huge waves with crests of white water. Some sort of mirror image.
Hi everyone, I am back and I see some great shots from everyone. I thought I’d share a time-lapse I took earlier this week.
Here is the link to Vimeo to cut and paste in your browser if the video is not displaying well (e.g., is cropped): vimeo.com/483792453
Yes, altocumulus I would say, Though there is a band of tiny clouds above the main one (above as in the picture, not necessarily in absolute terms) that would qualify as cirrocumulus by size. Are they part of a higher layer mostly hidden behind the lower one? Hard to tell.
The breeze is a very local phenomenon due to the sea and land having different temperatures, so it would not affect these clouds. The intriguing thing is that the clouds did not move for hours. That makes me think that there may be some orographic factor involved.
I also notice a bit of a sun corona drowned by the brightness of the sun. Hard to capture.
Looking forward to mode pictures from you, Steve.
Thanks for the info, Dave. I like the false colors, though not sure how much post-processing work they required.
I like the idea of a an IR cloud photos thread, but I don’t have much to contribute. You, however, based on what I see on Flicker, may have quite a few to share. I will certainly watch the thread.
One cheap (or fake) way to pretend shooting in IR is to use a deep red filter with the camera in b/w mode. I have one of those, so maybe I’ll try some imitation IR.
Dave, fantastic photos! I can only wish I can catch a situation like this.
I wanted to ask you about your camera. I just sent one for IR conversion. I am doing it for astrophotography, but I was considering cloud photography at some point (maybe after another conversion, possibly full removal of the filter). So I am curios what kind of conversion did your camera undergo. What kind of filter do you have now, if any, what range of the spectrum does it allow and how does that work for cloud photography?
This link shows the range of the h-alpha filter I am getting, all the way at the bottom.
I would appreciate your comments. Thank you.
