ALTAIR: Altair belongs among the brightest stars in the night sky. It's a part of the constellation Aquila and it's one of the three stars which are creating the Summer Triangle... This picture I took in July from Bortle class 3 in the Šumava National Park in the Czech Republic. Unfortunately, the conditions were bad and the clouds were coming up. But fortunately in this case the clouds are very profitable, because the light is diffusing on them, and the stars are more glowing, bigger, and brighter. And it does the picture nicer.

ALTAIR: Altair patří mezi nejjasnější hvězdy noční oblohy. Nachází se v souhvězdí Orla a je to jedna ze tři hvězd, které tvoří Letní trojúhelník... Tuto fotografii jsem pořídil v červenci z Bortleho třídy 3 v Národním Parku Šumava v České republice. Podmínky bohužel nepřály a mraky se blížily. V tomto případě jsou ale mraky naštěstí přínosné, protože se na nich pěkně rozptyluje světlo, a hvězdy tak vypadají zářivější, větší a jasnější. A to dělá fotku hezčí.

Observation date: 20 May 2023 (till morning of 21 May 2023)

Total exposure time: 53 minutes 30 seconds (321 light frames, ISO 400, 10s exposure at 50s intervals)

Approximate location: My backyard in Eden Glen, Edenvale, Gauteng

Equipment Used:

-----------------------

Unmodified Canon EOS 650D camera

Canon Zoom Lens EF-S 18-55mm 1:3.5-5.6 III, set at 18mm and f/4.5

Joby GorillaPod Hybrid tripod, Unguided

Acquisition via laptop with Astrophotography Tool (APT)

Post-processing Techniques Used:

----------------------------------------------

This image is the result of a single base image (containing the milky way and tracking mount with imaging gear) that was blended with a Milky Way sky mosaic image created from 321 light frames taken on the same night and from the same spot. The Milky Way sky mosaic image was created by stacking 5 groups of images in Sequator with 62 dark frames (no bias, flat and dark flat frames) and the resulting 5 stacked TIF images were stitched into a mosaic and further processed in PixInsight. Workflow included dynamic crop, background extraction, photometric color calibration, noise reduction with TGV Denoise and Multiscale Median Transform, non-linear stretch, green cast removal, colour saturation, removed magenta colour around stars, contrast enhancement with Curves and Histogram Transformation, star reduction, and further background smoothing with Multiscale Linear Transform. The single base image was also processed in PixInsight and the sky was replaced with the processed Milky Way sky mosaic image, keeping the true position of the Milky Way as in the base image.

This stacked 3-row panorama was taken right after midnight on July 18, 2021 facing the southern sky above Celtic Sea as seen from Hook Head in Wexford County. This is Class 3 Bortle magnitude sky but facing south from here means there is no artificial ligh sources to pollute the skies except from passing ships and the lighthouse. There was a particularly intense airglow from atomic and molecular oxygen in the upper atmosphere, that's why part of the sky is colored in shades of green.

This is a 4 section panorama stitched in Lightroom. Each of the 3 sky sections are made of 15 horizontal shots (15 seconds, 14mm, f 2.8, ISO 8000, Nikon D850) stacked in Sequator. The ground is 12, 30 second exposures. Bortle 1 sky. The light you see on the ground is from the starlight. The top of the photo is directly overhead. This section of the Milky Way is called the Orion Arm. The bright star in the lower left is Canopus, the 2nd brightest star in the night sky. The brightest star in all of the night sky is Sirius which is the bright star almost directly above Canopus. We can't see Canopus in Ohio. This was taken in Study Butte, TX, 29 degrees north of the Equator.

Stacked photo consisting of:

- 15 x background star shots stacked in Sequator to reduce noise

- 2 x light painted foreground shots

A fair bit of light pollution at this location but still worth going out.

Orion Seen Like Never Before 👋✨

I am happy I can show you my other winter landscape. The constellation of Orion, which dominates the winter sky, hides many beautiful hydrogen nebulae, and it has been a challenge for me for a long time because I was unsure how to make these nebulae visible. Finally, after I bought a modified 6D and gained experience, I am sure I can say I know how to do it!

And imagine that these skies were not very good. I was still in Bortle 4 or 5. However, the conditions were pretty good - around 5 °C above the inversion and no wind.

But most of all, the sky was covered with a strong airglow, which I had never had in my pictures before. And with it, the postprocess was quite tricky because of all the colors in the sky.

However, I am happy with the result! I hope I will be able to apply these experiences and have one more opportunity to take images of this sky this season.

final series of exposure, last one take at 4:30am, by then the sky was getting bright. Stack of (10) 30sec exposures, stacked with Sequator,

A test of the TT Artisan 50mm at f0.95. It does gather light very well, but you can see the off-axis wings. Not really a problem for portraiture, but unfortunately they spoil the wide aperture for astrophotography.

Close up view of the Comet NEOWISE

The comet C/2020 F3 (NEOWISE) is a once-in-a-lifetime opportunity so I decided to rent out the telephoto lens to shoot the close up view of the comet. Saltair is only 20 minutes from Salt Lake City but I'm shooting into the dark sky. First time tracking at long focus length (200mm) but I'm glad that there didn't seem any star trails.
