The Colorado Night Sky Panoramas during Fall
Just a touch of Colorado golden fall colors framed by the milky way and airglow last night at Lost Lake Slough along Kebler Pass. The back of the lake and trees sort of look like they are leaning toward the left but that's just an artifact of how the elevation of the ridge line reduces and how the lake curves toward the photo. If you look at the trees throughout the image, they are all vertical as expected. This image is contains 8 exposures overlapped at 50%. The panorama was captured using a Syrup Genie Mini ii. Equipment Camera: Astro-modified Sony A7R4 Lens: Sony 24mm Exif ISO: 3200 Aperture: f/1.4 Exposure: 13 seconds

The Colorado Night Sky Panoramas during Fall
How I captured a milky way panorama
I decided at 1 am last Saturday morning that I would drive out to the Black Canyon to capture the milky way! The Pulpit Rock Overlook is located around 30 minutes away from my house so with preparation, I arrived around 2 am and started capturing. Normally I attempt to shoot multiple foreground compositions, but this time I tried a different approach capturing only a single foreground to go with the sky panorama. It's possible that this isn't the best composition possible, but the full process of creating the panorama as well as the editing of the image was made much more simple because I didn't have to think about editing multiple foregrounds and figuring out how to compose each one with the sky. Overall I'm happy with the result and the process allows me to focus my time in other areas! This image is composed of 2 panoramas each contains 7 exposures overlapped at 50%. The panorama was captured using a Syrup Genie Mini ii. Equipment Camera: Astro-modified Sony A7R4 Lens: Sony 24mm The sky panorama: ISO: 1600 Aperture: f/1.4 Exposure: 13 seconds The foreground panorama: ISO: 1600 Aperture: f/1.4 Exposure: 30 seconds What has been your experience photographing night sky panoramas?

@Brian StPierre you probably want to brighten the whole image and add some contrast

Timelapse Astrophotography
10 timelapse photography tips: 1) Use a solid tripod. 2) Ensure there will be motion. Usually motion in the foreground and sky is better. 3) Ensure in fixed objects are positioned well compositionally. 4) Set proper interval using an intervalometer or in-camera timer. 5) Ensure you are capturing in RAW to be able to recover the most detail (dynamic range). 6) Use your camera's manual focus to ensure proper clarity throughout the composition. 7) Choose exposure, aperture, and ISO that effectively exposes both foreground and sky. 8) Double check exposure using the histogram. 9) Double check that all key settings like white balance, focus, etc are fixed. 10) Determine the time it will take to capture timelapse duration you need. Formula: capture time = (desired duration in seconds) x (frames per second) x (interval or exposure duration) Do you have any additional tips that you would add here?

@Brian StPierre It probably has better performance. My biggest complaint with the x3 is the overheating issues in the sun or over longer-term use...

@Brian StPierre I used my X3 yesterday out on a lake in cloudy weather without issues. Recorded for 10-15 minute segments in 5.7k. I feel that the x4 might perform better below 8k...
Capturing the Pink Moon
The full moon in April is called the pink moon because the time of year corresponds to pink wild flower season. The first image is the moon backlighting the clouds composed with the moon from the second image. The moon was actually in that position in the clouds, but I couldn't capture the clouds and detail in one shot. The second image is a stack of 30-40 images shot at 3 different exposures and then merged. The third image is a single exposure for reference. You may not notice a huge difference between the second and third images but if you zoom in on a large screen the detail is significantly better in the second image. If you really want the best detail, you really need to take thousands of images. Then select only a small percentage of the absolute best quality to merge to remove the noise and enhance detail. Have you ever tried to photograph the moon? I would love to see the results even if it's with a phone!

@Brian StPierre What did the individual photos look like? Make sure those are focused and properly exposed in camera. Here's a raw file from Thursday morning. If you don't see something like this on your camera, you need to adjust the ISO, Shutter, and probably focus. After capturing a photo ensure that you zoom in on it and details are clearly visible. Here is a link to one of my raw files: https://drive.google.com/file/d/1hTQyT0TKlYPG7CIl9GVHtJNEvkTIMwtu/view?usp=sharing
