This nebula is rightly named the Dark Shark nebula. This was my third try at capturing this one, with the first two not worth completing the processing. The nebula is both a dark and reflection nebula in the constellation Cepheus approximately 650 light-years away. The shark spans approximately 15 light-years head-to-tail.

This week in 2007, the space shuttle Atlantis, mission STS-117, landed at Edwards Air Force Base following the completion of a successful 14-day mission to the International Space Station. The primary mission objective was to deliver the second and third starboard truss segments, S3 and S4, and another pair of solar arrays to the station. Today, the Payload Operations Integration Center at NASA's Marshall Space Flight Center serves as "science central" for the space station, working 24/7, 365 days a year in support of the orbiting laboratory's scientific experiments. The NASA History Program is responsible for generating, disseminating, and preserving NASA’s remarkable history and providing a comprehensive understanding of the institutional, cultural, social, political, economic, technological and scientific aspects of NASA’s activities in aeronautics and space.

Hi Folks,
I just published a new imaging project on my website.
Messier 101 - The Pinwheel Galaxy with the recently discovered supernova - SN2023ixf!
This target is located 21 Million light-years away in the constellation of Ursa Major.
This was about a 3-hour exposure in LRGB using my widefield Askar FRA400 Platform.
Everybody and their brother seems out there shooting images of this galaxy with its supernova.
And who's to blame them? Supernovae are amazing events. At the end of its life, a star explodes, releasing as much energy in one second as our Sun will emit in its entire lifetime!
This does not happen every day, and to have one in a galaxy as beautiful as the Pinwheel is worth shooting.
But with so many images of this out there - why should I shoot it tool. Do I think I can do better than everyone else? Hardly!
This is such a cool event that I did want to have one captured in my portfolio.
But during my last imaging session, my widefield Askar FRA400 Platform was the only scope that was untasked. During galaxy season, there are relatively few large targets to shoot. So I pointed it at M101 and decided to go for it!
My expectations were very low, though:
- A widefield scope shooting a galaxy - that will be a problem!
- I was only able to get 3 hours of integration - my last shot of M101 had 11 hours - so that's going to be a problem
- I am shooting with some thin smoke from the Alberta Wildfires in the air - that IS a problem.
So why shoot it at all?
- Supernovae are one the coolest events in our night sky - I wanted to capture an image of that - even a poor one!
- I saw this as an opportunity to dive into what supernovae were all about and describe that in my web write-up
- I have the twisted part of my personality that likes the challenge of getting a better image out of compromised data
I drizzle processed, then cropped like mad, and took advantage of BlurXTerminator and NoiseXTerninaor to help improve a dicey image.
The final result is not wonderful, but it is not horrible either!
The full story of this imaging project, and some cool info on supernovae, can be found here:

Thanks,
Pat

Rilke again:
Have patience with everything that remains unsolved in your heart. Try to love the questions themselves, like locked rooms and like books written in a foreign language. Do not now look for the answers. They cannot now be given to you because you could not live them. It is a question of experiencing everything. At present you need to live the question. Perhaps you will gradually, without even noticing it, find yourself experiencing the answer, some distant day.
~ Rainer Maria Rilke, Letters to a Young Poet ~

And last but not least:
Imagionation is the mother of all possibilities.
(I'm not absolutely sure, but I suppose C. G. Jung said or wrote this once.)

My Cable Car , officially the State Cable Transportation Company My Cable Car, is the public company responsible for the administration of the La Paz - El Alto Cable Car urban transport system, which links the cities of La Paz and El Alto , as well as a line tourist in Oruro in Bolivia . The first of its lines began operations on May 30 , 2014 . At the end of the first three lines, it became the longest urban transport cable car network in the world. [On March 9, 2019, the last line corresponding to the second phase of implementation was inaugurated: the Silver Line, which closed the circuit called the Metropolitan Integration Network, and became the tenth line in operation. The system was raised in response to various problems in the metropolitan area of La Paz , made up of the cities of La Paz and El Alto that had a precarious public transport service that did not respond adequately to the increasing demand from users and significant expenses in time and money involved in mobilizing between the two cities, in addition to the chaotic traffic and with high levels of environmental and auditory pollution they generated, the growing demand for gasoline and diesel, which are subsidized by the state. The service allowed the effective connection of the city of La Paz at an average height of 3600 meters above sea level, which has an intricate topography, surrounded by mountain ranges and diverse rivers with the city of El Alto settled on a plain located at 4100 meters above sea level. , reducing travel times and costs.
The cost of the ticket on each line is 3 bolivianos per person. When transferring to another line, the cost is 2 Bolivians. The service allows you to transport bicycles paying an extra ticket except on weekends on the Green and Yellow Lines.

The ever patient and reflective Spirit of Earth, Onua is as steadfast and wise as the earth itself.
Back in 2020 I challenged myself to get back into the hobby and build a MOC a month. This was the fourth build I finished.
Just a typical Toa Mata revamp, nothing crazy or neat. This guy was an exercise in first tries, specifically color blocking and using CCBS shells and connectors in a build. I initially stopped MOCing back when Hero-Factory had just come out, so CCBS has been pretty new to me. Throughout 2020 and 2021 I've been trying to incorporate in into my building style as much as I can. There's so many neat parts and it's been fun seeing how people integrate them and learning how to do so myself.
9hr 50min Integration over 8 nights, from end of December 2020 to start of January 2022.

...this is one of my oldest images...but i relly love it...i never seen a scene like this before and after in berlin...she was in the park with her husband and kids...they played basketball...suddlendy she went up and through a few balls...luck that i have my camera with me...
...i hope some more people view and like it...

The brightest and most accessible to photography cluster in the constellation of Coma Berenices.
336 million light years from earth. Contains over a thousand different galaxies (most of them are elliptical) and huge amount of dark matter.
One of the few places in the sky where most objects are galaxies and not stars

I am taking a different turn in photography.
I love incorporating art with photographs so now I play with my iPad and Laminar software.
Thus allows me to layer my bits and pieces hopefully into a more interesting landscape.

de la nature, la poésie, la sensualité... tout qui me parle, tout que j'ai envie d'exprimer.
J'avais passé des années en faisant de collages de papier, de peinture et de photos. Maintenant, je reviens sur mes racines artistiques et j'ai commencé à faire une nouvelle série de superpositions. Voici la première.

of nature, of poetry, of sensuality... all that speaks to me, all that I desire to express.
I had spent years making collages of paper, paint, photographs. Now I am revisiting my artistic roots, and I have started a new series of photo composites. Here is the first.
