David's Images of the Day Photoblog
Today, I captured images of an airplane, two jets, and a Turkey Vulture transiting the sun while looking at the sunspots (we are at or near the solar maximum). I was viewing the sun with a Vespera Classic and Vespera Pro automated telescope using solar filters.
Today, I captured images of a flock of geese and several jets transiting the sun while looking at the sunspots (we are at or near the solar maximum). I was viewing the sun with a Vespera Classic and Vespera Pro automated telescope using solar filters.
In addition to the sunspots (we are at or near the solar maximum) I captured two jets transiting the sun using a Vespera Pro telescope fitted with a solar filter.
The comet is getting fainter and the tail shorter. The magnitude is now 10.0. The first image is a composite of 31 images (5 min 10 sec) and the second one is a composite of 90 images (15 min). In the second image there is some movement of the comet head. Also, the comet is moving into a region of the sky with part of the milky way in the background (many more faint stars).
Yesterday the sky was overcast, so no comet images. The comet and tail keep getting smaller and fainter. The estimated magnitude of the comet was +8.2. I am only showing images from the Stellina telescope since the Vespera telescopes are fitted with filters for viewing emission nebulae.
The full “supermoon” this month was extra bright because it was closer to earth. Once it was above the trees to my east, I used the Stellina telescope to record images for a time-lapse video. While reviewing the images I found several images with silhouettes of birds passing in front of the moon. At this time of the year, birds are migrating south, often at night. Even though it may have been a large bird, it must have been a long way away. The cropped image is about 4x magnification.
While reviewing the solar images with several sunspots, I noticed what appears to be a pair of satellites transiting the solar disk over a 4 second period. I have a composite image and the individual images of the transit. I also found images with silhouettes of birds (Turkey Vultures?) and one with an unidentified object (military jet?). I’ve also added the time-lapse video if you want to look for other objects passing in front of the sun.
The comet is still visible to the telescopes with an estimated magnitude of +6.8. The tail is fainter and shorter than yesterday. The Vespera II telescope was fitted with a CLS (city light suppression) filter causing the tint to the image. The length of the comet tail can be estimated based on the field of view for the telescope’s digital sensors. Stellina (1.0° x 0.7°), Vespera Classic (1.6° x 0.9°), Vespera Passengers (2.4° x 1.8°), Vespera II (2.5° x 1.4°), and Vespera Pro (1.6° x 1.6°). The jpg images were processed to increase the brightness (Capture One Pro) and reduce the noise (Topaz AI).
