@jerryy, does this mean you want some more or you've had enough of these ? 😀

jerryy got a reaction from George_P in Astro-photography (open thread)
Big Bear, Big Dipper...
Every now and then one of the images I post will have an asterism, which is just a pattern in the stars that is interesting to see, but the stars have no relation to each other unlike stars in constellations. There is a famous one where both happen at the same time, the stars are in an asterism and in a constellation...
This is a screen capture from Stellarium, with annotated star names added on top. All of the stars are part of constellation Ursa Major. The blue-ish colored lines and the white-ish colored lines connect the main constellation stars, the white-ish colored lines alone form asterisms. The orange-ish colored labels are for the stars in the two asterisms.
This is the equivalent of an 80 seconds exposure.
As a side note: Alcor and Mizar are a famous double star pair, very easy to see visually or with binoculars or telescopes.

"Will you walk into my parlour?" said the Spider to the Fly” *
Back on page one of this thread, there is a post showing a quick exposure isolating IC 405, The Flaming Star Nebula. That section of the sky has so many things to see it is almost a tourist-oriented nature-viewing area.
Some of the highlights include tadpoles, starfish, spiders, flies, pinwheels and more.
This is the equivalent of just about 56 minutes of exposure.

Will the spider once again coax the fly into its parlour? Will the fly escape the machinations? Their exchange is in the sky for us to ponder...

jerryy reacted to JoanneC in Fuji newbie
I just wanted to say hi to everyone. I am a former Canon user, but have sold off all of my Canon gear and starting over again with Fuji.
I used to shoot weddings and such back in film days, happily switched to DSLR later on.
Since I am on a fixed income, I have to be much more selective when buying gear, so I spend my time shopping used gear.
I have an X-H1 that I am using with some adapted vintage lenses and a TTartisans 27mm.
I am interested in street photography, outdoor/ landscape and especially astrophotography.

jerryy reacted to Hannes in Aurora Borealis with GFX100s and Laowa 19mm F2.8
Hi
I have tried to make Northern lights photos the first time in my life. I used 2000 ASA, f2.8 and 2 seconds. The aurora borealis was moving around quite fast and with more than 2 seconds the pictures came out like fuzzy mush. To find infinity on the fully manual Laowa lens has to be done in advance, I marked it on the body of the lens.
What do you think about the result?
Kind regards, Hannes

I am going to stick with guessing it is a hardware issue, those chips can have many (+) and (-) traces going into them so that the cells are supplied with juice all at once rather than one at a time. A cold solder joint can cause one set of cells to not be refreshed properly while the others are just fine. But, this will take some diagnostic efforts to trace. a software issue on the other hand would show up in more than one camera body.
I do hope you are able to get this resolved.
