Something a little different today! This is a composite image of the sun, showing the surface detail and prominences, while being photobombed by a passing plane.
The image was taken using an Altair GPCAM 290M with a 0.5x focal reducer, attached to a Lunt LS50Tha 600B PT solar scope. The image was captured using SharpCap Pro, pre-processed using AutoStakkert2 and Registax6, with final processing done using Photoshop CC.
This image was captured with a 60% histogram. The image immediatly preceeding this one was captured with an 80% histogram, which is my usual exposure. At this setting, a portion of the left-most edge of the North Polar Hood (NPH) has been getting clipped in my latest images. I took the two images for comparison..
This image was able to endure more sharpening with less clipping than the 80% histogram image. It is also interesting to compare how the details south of the NPH differ between the two images. I am not certain which image I like best.

Image captured with a Mewlon 210 and ZWO ASI533C camera, stacked with Astrosurface and sharpened with Registax.
I decided to try a new approach to photographing the sun in hydrogen alpha, and in the process, I decided to revamp my processing methods.
There was very little in the way of activity on the sun today, in fact just a couple small prominences and a filament.

This image was captured with an 80% histogram, which has been my usual practice lately. At this exposure level, a portion of the left-most edge of the North Polar Hood (NPH) has been getting clipped in my latest images. I took this image for comparison to image that follows this one, which was captured with a 60% histogram.
The image with the 60% histogram was able to endure more sharpening with less clipping. It is also interesting to compare how the details south of the NPH differ. I am not certain which image I like best.

This artist's concept puts solar system distances in perspective. The scale bar is in astronomical units, with each set distance beyond 1 AU representing 10 times the previous distance. One AU is the distance from the sun to the Earth, which is about 93 million miles or 150 million kilometers. Neptune, the most distant planet from the sun, is about 30 AU.
Informally, the term "solar system" is often used to mean the space out to the last planet. Scientific consensus, however, says the solar system goes out to the Oort Cloud, the source of the comets that swing by our sun on long time scales. Beyond the outer edge of the Oort Cloud, the gravity of other stars begins to dominate that of the sun.
The inner edge of the main part of the Oort Cloud could be as close as 1,000 AU from our sun. The outer edge is estimated to be around 100,000 AU.
NASA's Voyager 1, humankind's most distant spacecraft, is around 125 AU. Scientists believe it entered interstellar space, or the space between stars, on Aug. 25, 2012. Much of interstellar space is actually inside our solar system. It will take about 300 years for Voyager 1 to reach the inner edge of the Oort Cloud and possibly about 30,000 years to fly beyond it.
Alpha Centauri is currently the closest star to our solar system. But, in 40,000 years, Voyager 1 will be closer to the star AC +79 3888 than to our own sun. AC +79 3888 is actually traveling faster toward Voyager 1 than the spacecraft is traveling toward it.
The Voyager spacecraft were built and continue to be operated by NASA's Jet Propulsion Laboratory, in Pasadena, Calif. Caltech manages JPL for NASA. The Voyager missions are a part of NASA's Heliophysics System Observatory, sponsored by the Heliophysics Division of the Science Mission Directorate at NASA Headquarters in Washington.

A hot sunny afternoon with some breeze and the telescope tube wrapped with kitchen foil to alleviate thermal gain. A challenge to get the subject to an acceptable focus and difficult seeing conditions during capture. I had to shroud myself and the laptop with a large towel to view the screen.
Out of 8000 frames captured, about 1600 used for processing. Final image enlarged to 150%.

Due to driver glitch, the filter wheel did not change fillters during the capture.. Since the three color channel images were identical (and probably captured through the blue filter, the result was a monochrome image.

Mars images from October 2020 to March 2021. I had to go about three months between the last two images due to poor weather and when clear poor seeing at my location. Image show size, distance and dates for each image. Size is measures in arcsecond. Data captures with a Meade 12" LX200, ZWO ASI174MM camera.
Fighting twilight on the morning of July 11, but it might put on a good show in evenings after July 14th.
The comet is named for a NASA spacecraft that discovered it, the Near Earth Objects Wide-field Infrared Survey Explorer (NEOWISE). The spacecraft examines the infrared signatures of near-earth objects. It's a follow-on of an earlier mission, WISE.
