I just arrived back home from a short trip to Florida and the night sky was clear. Comet C/2022 E3 (ZTF) is now visible in the early evening sky. Both the Stellina and Vespera telescope/cameras were used to capture images. The telescopes automatically track the motion of the stars in the sky while taking 10 second images. During the time of the observations (15-63 minutes), the comet is moving, creating a tail in the image. This motion can be viewed in the time-lapse video.

After several days of clouds and rain, the skies finally cleared. I had both the Stellina and Vespera systems out. There currently several active sunspots. During the night I captured images of the Andromeda Galaxy (M31), Orion Galaxy (M42), Rosette Nebula (NBC 2237), Satellite Cluster (NGC 2244), Pinwheel Galaxy (M101), and the Moon. Also, I used the manual mode to search for the Comet C/2022 E3 (ZTF). It was finally high enough to be viewed to the northeast over the house from my patio. I used the Sky Live website to get the location, and then just plugged the numbers into the Singularity application. Within minutes, both the Stellina and Vespera systems had the comet centered and started taking images.

For the following images, I processed the final JPG image with Topaz AI, followed by Capture One Pro. For the raw TIFF images, I needed to use Capture One Pro first, followed by Topaz AI. Follow the link to my PhotoShelter Gallery for larger views of the images. The nebulae images taken using the dual H-alpha, O-III filter are more vivid.

Since it was a dark night, I also set up a camera to capture images for a composite star and jet trails view looking north. Polaris isn’t exactly at the celestial north point. The file size is 11656 x 8742 (403.4MB).

It was cold and breezy in the morning, but the sky was clear. So I decided to try out the Vespera Astro-camera with a solar filter to view the sun. I followed the instruction on the Singularity app and within 10 minutes was getting solar disk images with several sunspots. Unlike the nighttime observations where multiple images are used to make a composite image, the camera is taking individual images. It continues to track the position of the sun for as long as images are being recorded. I made a short time-lapse video shown below. One of the images captures the silhouette of a jet passing in front of the sun.

The sky was clear again in the evening. I set the camera up just after astronomical twilight. I replaced the solar filter that I used earlier in the day with a dual band filter. The filter transmits wavelengths of light from the Hydrogen Alpha (H-alpha) and Oxygen III (O-III) emission bands seen in nebula. The filter has a sensor that lets the camera know that it has been installed. Presumably to adjust the sensor acquisition parameters. The filter appears to really improve the detail and contrast of the nebula images. During the night I used the Vespera to obtain images of the North America Nebula (NGC 7000), North America Nebula (M45), Crab Nebula (M1), Jellyfish Nebula (IC 433), Rosette Nebula (NGC 2237), Orion Nebula (M42), De Mairan’s Nebula (M43), Thor’s Helmet Nebula (NGC 2359).

I also set up a camera for a star trail image looking south. The same general direction that is open for the deep sky Vespera astro-camera from my patio. Unfortunately, the raw file format (*.3FR) from the Hasselblad camera is not recognized by Capture One Pro. So this star trail image is a composite of the jpg images processed by Capture One Pro and PhotoShop CC.

Daily Electric Energy Used (169.2 kWh) from Sense. Daily Solar Electric Energy Produced (29.4 kWh) from Sense. Sunny. Deficit of 139.8 kWh. This is most electricity used in one day since I started monitoring. Mainly because the GeoThermal HVAC needed the resistance heaters to boost the amount of heating needed to keep the indoor temperature at 66°F. The outdoor temperatures are supposed to get warmer over the next few days.
Hamlett’s Tree folks continued clearing the “back 40”. The last of the dead Ash trees were removed. Individual B&W images taken with a Leica Q2 monochrome camera, and a time-lapse video taken with a Fuji X-T3 camera.

Birds of the day viewed in my backyard: White-breasted Nuthatch, Song Sparrow. Note, I spent the morning using a brush mower to cut back the weeds and didn’t spend much time looking for birds. I only saw one Ruby-throated hummingbird, but wasn’t able to capture an image.
