A Sultry Evening...
One my favorite things to do... Watch a ominous lighting intense storm come over the horizon. With continuous cloud to cloud lightning & a few cloud to ground strikes. This was one of those perfect photogenic Nebraska storms.
Severe warned right after sunset. Found an open spot to shoot just some incredible June storm photography for 2022!

Day and night, darkness and light, silence and noise. I got here in that twilight between night and morning, and watched the sunrise develop, mind wandering in the wait, as always. There have been various colorations in the sky, but too much contrast between the dark of those deep valleys and ridges, and the brightness above. When I stepped from the car a half hour ago, I broke the silence and a dog began barking somewhere down in that mist; the idiot went on incessantly till we reached a standoff of me making no sound and him convinced he'd scared it off. The glow now has begun to separate those ridgelines and peaks, and throw some highlights on the mist wafting through the nearest valley. This is the balance I've waited for in camera, with terrain no longer a dark blob versus the skyglow of the rising sun. Though my eyes see it differently, the machine has limitations on what it can record; I work awhile as the sun comes up. Back at the car the dog starts up. I search for balance.
More of my somewhat unique filter approach: Ha and Blue (Edge) and luminance from the 8" newt. Ha and blue combined HBB.

Do light pollution filter improve astro imaging from moderately light polluted sites?
The theory is clear: These filters help to reduce the sky glow from warm light sources, especially sodium vapor streetlights, but they will not help much against the newer generation of LED lights. While you therefore cannot expect wonders, you should be able achieve better contrast from sites with a fair amount of older streetlights.
On the other hand, I have never done a comparison of what I can achieve with and without one of these filters. While taking my first Milky Way core shots of this season from a Bortle class 4 site, I took the chance and shot same panorama back to back, first without and then with my light pollution filter.
During post processing, I independently processed both panoramas with my normal workflow. The results show that it is possible to correct moderate light pollution during post processing to a big extent, but processing the unfiltered image was more difficult and there still is slightly better contrast in the filtered image.
In the filtered image however, the brightest stars and Jupiter on the very left have slightly more glare and if there is stray light, I have a hard time controlling reflections, as I cannot attach the lens hood with my 150mm filter holder in place.
Another drawback of any filter is that it reduces the light arriving at the sensor. With the light pollution, I lose about halve an f-stop and have to expose about 50% longer. This is not a big problem if you are tracking the sky, but might be a deal breaker if you shoot from a fixed tripod
.
So wat do you think? Are light pollution filters worth the price and hassle?

Target: Banard-150 Seahorse Nebula
This is what's called a Dark Nebula. Instead of Hydrogen and Oxygen gases glowing as a reaction to certain wavelengths of light from stars, here the dusts and gases are dense enough to block visible light from stars behind them. This one's rightfully named the Seahorse Nebula, it is located in the Cepheus constellation about 1200 light years from Earth.

Not as much integration as I would like due to clouds, but I have never imaged this before so decided to make the best.
Initial impressions are more of a tight open cluster. The globular aspects only come out after processing.

Not many Cities have a municipal elevator. Oregon City does though, and its an icon. Its one of only 4 in the world. The elevator takes you from a historic downtown, just next to the the underrated cyborg-like Willamette Falls (one of the largest and most powerful falls in North America), to the historic McLoughlin House (basically the founder of Oregon as we know it). The elevator is also technically a street, even though its vertical. The structure itself is the second version of the elevator and the result of a design competition in 1954. The elevator and space-ship-like observation deck were designed by Gordon Trapp in an art deco masterpiece.
I actually set out to shoot the structure from, and within, the bridge below, the aptly named, Oregon City Bridge built in 1922 by famed bridge builder Conde McCullough. This one was always his favorite. I wanted to shoot the tower by standing in the middle of the street so the arches of the bridge framed the tower. Great idea, but traffic on the bridge made this a difficult feat. So this was plan B. I am glad I tried this. I have seen many images of the elevator, but I wanted to include the bridge below. The skyglow form West Linn helped frame the scene.
Let me know what you think. I know this is a departure from the usual landscapes I post, but its nice to shake things up a bit now and then. My brother hates nature, so he should love this one. Here's to you nature-hater!

I used color data from previous years and have no idea about exposure times or dates or even specific equipment. I also moved colors around so likely there is no connection between "Ha. Oii" etc and colors here. I just listed a somewhat generic guess as OSC data time.
That said its my best attempt at what has become a yearly pilgrimage, so I'm pleased (I guess until next year's attempt).
Three panels over three nights of Ha as the basis of this latest incarnation.

This image was one I've been working on for awhile. The highest resolution image I've worked on to date. This is a 57 exposure shot of our Milky Way arching over Rose Canyon Lake, Arizona. Tucson light pollution only 20 miles away, but at over 7,000 ft, it has little effect on the clarity of the Milky Way away from the glow.
As I grow as a photographer, I find it ever more difficult to let little things go in my images. Some have said it may be detrimental spending so much time editing... that people love quantity over quality, but I refuse to believe that. I hope I never settle, and always strive to better my last.

One of my favorite Nikola Tesla quotes:
"A single ray of light from a distant star falling upon the eye of a tyrant in bygone times, may have altered the course of his life, may have changed the destiny of nations, may have transformed the surface of the globe, so intricate, so inconceivably complex are the processes of nature."

The rocks and trees at Bandon, Oregon are quite photogenic. This day the sky glow added extra beauty.
This is my second go at capturing the Milky Way in a Photograph. The last one was 2 years ago. This was taken with a fisheye lens which causes the curve up in the foreground. This shot was taken on a clear night last Tuesday evening coinciding with a few days after the peak of the Perseid Meteor Shower. I saw some quite good ones but none coinciding with when I was taking a picture. This part of the South Coast of England is far from ideal for taking the Milky Way. Pagham Harbour is a nature reserve a mile from home and a small gap in the coastal sprawl of light pollution. Light glow from Bognor Regis is just a few miles to the east while to the West there are coastal towns such as Selsey and the strong light glow from the City of Portsmouth about 17 miles away as the crow flys. Luckily from my location at the Harbour Mouth the Milky Way was in the gap between glows. The Milky Way is the brightest central part of our Galaxy. The best parts can only be seen in the summer because the sun is in that area in the winter. The best times are April through to September.
The other major feature in the picture is Mars. The Planet is at its closest to us since 2003 and is 10 times brighter than normal. It can be seen in the picture in the middle bottom and is bright enough to create a reflection in the water. It was at its closest at the end of July but will remain very bright for several months yet. In the UK Mars rises this month after sunset and is visible most of the night low in the southern sky
I checked on suitable settings for the image. These are not accurate in Exif as the Fisheye is a manual lens. I used my widest aperture of f3.5, 30 seconds and ISO of 2000. Most wide angle lens require 20-25 seconds to avoid movement showing in the stars. With the Fisheye I was able to go to 30 seconds. The image was taken at 10.46 just a minute after the end of Astronomical Twilight when the sky will be at the darkest it will get. The moon had set 30 minutes earlier. The foreground was lit by surrounding skyglow from light pollution. I took shots until 11.30. I used the in camera Noise Reduction and a remote trigger device. It was quite warm at 17C and no problem with condensation.I used a Sony A700 with a Samyang Fisheye lens at 8m. Taken with a Tripod looking south over from the Harbour Mouth looking over the shingle spit at mid tide.
A lot of steps were taken in the processing to bring out the milky way starting with Raw adjustments. This was followed by Topaz DeNoise which removed quite a large amount of Noise. Then Topaz Clarity to bring up more detail. I used various Brightness contrast adjustment layers with masks to brighten and darken various parts of the image including darkening the light pollution and brightening the Milky Way and foreground. A Photoshop Action was used from Astronomy Tools to select and brighten the stars..

The bright streak of light in the sky here is an iridium flare, which is sunlight reflecting off a satellite. The green skyglow is a faint aurora, a luminous atmospheric phenomenon appearing as streamers or bands of light sometimes visible in the night sky in northern or southern regions of the earth. Gotta love science!

I recently rejoined the Royal Astronomical Society of Canada - Toronto Centre after a long absence. This photo (part of a time-lapse video) was taken during two nights of observing at the E.C. Carr Astronomical Observatory (RASC - Toronto Centre) in August 2016. It was my first weekend at the facility and I was fortunate enough to set up my C11-CGEM scope inside the Tony Horvatin Observatory for two consecutive nights (structure on the left). The seeing and transparency was moderate to poor on both nights with exceptionally warm temperatures and humidity. Some air and skyglow was also present. Nonetheless the Milky Way was still a sight to behold !
I did not light paint or highlight the foreground as I want to show just how dark the site is and stress the importance of using red light in order to keep eyes adapted and imaging sessions from being disturbed.
More about the CAO:
I have no idea how much exposure ended up on this. A couple nights ago I was able to try a few hours of narrowband Ha and Oiii (2 minute subs), so started with HOO (which is a really nice pallette- first time trying that).
Then I added a previous year's LRGB to get more of the reflection nebula blue. Back to clouds now, so here is where it will stand.
With the cloudy winters it took me 3 years to get another crack at M42 , so I was happy to have the opportunity and play with the narrowband data.

Another picture from years back. This was not long after I first got into astrophotography. I traveled to Ecola Park near Cannon Beach, OR and snapped this shot over the bay to my south. It was a beautiful night. Oregon's iconic Haystack Rock is visible in the distance
Description
Finally after 3 1/2 months a full night of clear! My cup runneth over..
Over the rains I tuned up the mount and made a few other small changes. I'm pleased that its tracking well over the 2 minute subs. I think I only tossed 2 subs. I lost more due to passing clouds..

The view from Scotty's Castle Road in Death Valley National Park at 3am on a windy night in April. The specks of light on the ground are Furnace Creek in the middle of the frame (distance 38 miles / 61 km) and Stovepipe Wells on the right (distance 21 miles / 34 km).
The photo is a stack of 64 eight-second exposures, with an additional six-minute exposure blended in to get more detail in the landscape. The skyglow on the horizon near the left and right edges of the frame is caused by the lights of Las Vegas and Los Angeles. In reality the effect was much stronger than in this picture. A didymium filter on the camera reduced the glow somewhat; most of the rest has been removed digitally.

Comet Leonard (C/2021 A1) on the morning of December 10, 2021, with a 28mm wide-angle lens for a field of view of 65° x 46°. The comet is at far left, in the east, to the left of the bluish band of Zodiacal Light in the southeast in the pre-dawn sky. The Light was fairly obvious to the eye but is partly lost here in the skyglow from the lights of the town of Bassano and with some bands of red airglow as well lighting the sky. Arcturus is at top; Spica is at far right.
The Zodiacal Light follows the ecliptic, so with the comet north of the Zodiacal Light, it shows how its orbit was inclined steeply to the ecliptic. The comet was closest to Earth and crossing the ecliptic plane heading south 2 days after the date of this image.
Taken about 6:00 am MST. The distinctive cyan tint of a comet's coma is prominent. The comet was in Serpens at the time.
This is a stack of 4 x 1-minute exposures at f/2.8 with the 28-70mm Canon RF lens on the Canon EOS Ra camera at ISO 800. The ground comes from a single exposure to minimize blurring. The rest of the sky stacked with a Median stack mode to help eliminate satellite trails. Taken from home in southern Alberta.
