A galaxy 32 million light years away!

Another test image using my new Celestron StarSense AutoGuider. This is using 4 minute exposures, and the tracking is very good for an 8" SCT at F6.3, 1200mm focal length. Not the best processing but I'll get more data next month and try again. It's a cool galaxy!

It's been a while since I took an image of this beautiful galaxy group, and given my new processing skills I thought I'd revisit them. This is two nights' worth of data (4 hours total).

The Leo Triplet is a captivating group of three interacting spiral galaxies located approximately 35 million light-years away in the constellation Leo. It consists of Messier 65 (M65), Messier 66 (M66), and NGC 3628 (often called the "Hamburger Galaxy"). These galaxies are gravitationally influencing each other, which is evident in the slightly distorted spiral arms of M66 and the warped disk and prominent tidal tail of NGC 3628. Despite their close proximity and ongoing interactions, all three can often be viewed within a single field of view through a telescope, making them a popular target for amateur astronomers.

The Rosette Nebula is certainly one of the most popular astronomical objects in the northern hemisphere. Its size and brightness make it accessible even to smaller optics, while intricate details leave enough room to play for the more ambitious observer.

Curiously, it is listed under not one but 5 NGC catalogue numbers, which nowadays designate slightly different regions of nebula and open cluster: NGC 2237, NGC 2238, NGC 2339, NGC 2244, and NGC 2246.

Also, I find this nebula a prime example of an optical illusion (or maybe a Rorschach test): Depending on field size, exposure depth, image orientation and also personal inclination, you can either see an intricate flower, or a human skull. What do you see?

This is one of the first few objects caught with the William Optics Redcat 71 widefield astrograph that was installed just at the beginning of this year on the observation platform of the Volkssternwarte München, and which I have been testing enthusiastically since then (also thanks to several occasions of clear weather). I expect this to be used heavily for video astronomy from now on, certainly by me!

The Great M13 Hercules Globular Cluster. This cluster contains over 300,000 stars and lies around 25,000 light years away, situated just outside of our galaxy. It is about 11.65 billion years old, making it almost three times older than our Earth.

The 1974 Arecibo message, which contained encoded information about the human race, DNA, atomic numbers, Earth's position and other information, was beamed from the Arecibo Observatory radio telescope towards M13 as an experiment in contacting potential extraterrestrial civilizations in the cluster. The cluster will move through space during the transit time; opinions differ as to whether or not the cluster will be in a position to receive the message by the time it arrives.

This picture was captured using a telescope with a Hydrogen-alpha (Hα) filter. This lets us see the Sun's chromosphere. The area featured is cataloged as Active Region 2941 (AR2941), The bright area is a "plage". It is extremely hot and bright. On each end you can see a sunspot. If you were using a telescope with a "white light filter", you would not see the same features as you would be looking at the the Sun's photosphere. However, you would see many more sunspots in AR2941 that are obscured here by the plage. There are also filaments seen in this picture.

I polar aligned my mount using SharpCap Pro. My Sony a7rIII and adapted Nikkor 500mm f/4 P AI-S were mounted on an ADM vixen rail and secured to the SkyWatcher EQ6-R mount. The guide scope/camera was attached to the camera's hot shoe. I used PHD2 to autogude during the imaging session. DeepSkyStacker was used to combine all frames, and the outputted TIFF file was brought into PixInsight using: STF, Cropping, Dynamic Background Extraction, BlurXTerminator, plate solving, color correction, NoiseXTerminator and then the DSO was separated from the stars, and both files processed and stretched separately and then recombined using PixelMath and lastly HDR Multiscale Transform to bring back detail in the nebula's core. That file was brought into Lightroom for Metadata and EXIF tags, light post-processing, and cropping to the final image.

Better processing thanks to a new star reduction script I learned about and utilized, as well as better color calibration.

My software (Stellarium) was insisting that both of these objects could fit within my field-of-view, given my camera and scope combination. While watching meteors this weekend, I gave it a try, and much to my delight the software was correct! So, here are both nebulae in the same image!

The Lagoon Nebula (left) is a giant interstellar cloud in the constellation Sagittarius. It is classified as an emission nebula and as an H II region. The Lagoon Nebula was discovered by Giovanni Hodierna before 1654 and is one of only two star-forming nebulae faintly visible to the eye from mid-northern latitudes.

The Trifid Nebula (right) is an H II region in the north-west of Sagittarius in a star-forming region in the Milky Way's Scutum-Centaurus Arm. It was discovered by Charles Messier on June 5, 1764. Its name means 'three-lobe'.

The Pleiades, also known as the Seven Sisters and Messier 45, are an open star cluster located in the constellation Taurus. Robert Burnham states in his Celestial Handbook, "undoubtedly the most famous galactic star cluster in the heavens, known and regarded with reverence since remote antiquity."

Work in progress as I would like to add several more hours if/when the weather cooperates!

Did you know that J.R.R. Tolkien told us in The Hobbit that the Pleiades were known in the ancient days if Middle-earth as Remmirath, or "The Netted Stars"?

I decided to remove the Hyperstar for once to try my hand at some prime focus imaging with the 11" Celestron EdgeHD. I was after some planetary captures (Venus), but I had software issues(Sharpcap). Unitl I had them fixed, Venus had set in the West. So before the clouds moved in, I decided to capture some quick Luminance filtered images of NGC7023, the Iris Nebula
