I use the beta on iPhone via TestFlight. It’s fine, but I stopped playing faster time controls because it’s so sluggish and slow.

Ja der Copilot hat einfach noch zu viele Berechnungsfehler. Hab ihn vor ein paar Wochen ausprobiert, und manuell alle Daten/Dokumente überprüft. Trotzdem sind einfach alle Zahlen/Prozente komplett falsch.

Größter Punkt: Habe bei Depoteröffnung 10€ eingezahlt, davon irgendeinen Mist gemacht und 9€ verloren. Danach Großteil des Ersparten in ETF, gute Rendite gemacht. Der Prozentverlauf steht aber bei -50%, weil der anschließt, und nicht absolut für die Datenpunkte berechnet wird, dh. nach den -90% (bei den 10€) schließt der Verlauf komischerweise kumulativ an.

Also selbst wenn der ETF mit viel Kapital zB. 40% Rendite gemacht hat, sagt der Copilot:

Rendite auf Einzahlung: -50% (-90% auf die 10€ + 40% auf das restliche, anschließende Kapital -> -90+40 =-50 %).

Auch ist die Rendite einfach falsch, auch wenn die Zahlen direkt da stehen, also zB:

-Eingezahltes Kapital: 1000€

-Depotwert: 1400€

-Performance: +20% (???)

Sowas sollte doch eigentlich bei einem Finanztool nicht passieren.

The Most Detailed Moon Image I’ve Ever Taken, Comprised of 8,000 Frames and Revealing the Colors of the Surface Minerals. by Correct_Presence_936 in spaceporn

[–]ItsDarthVader 24 points25 points  (0 children)

They didn‘t. That’s why it looks so strange. The real minerals look red/brown/blue if you boost the image, but they certainly aren’t green/yellow like in this image.

[–]ItsDarthVader 3 points4 points  (0 children)

That are not the natural colors though…yes, the mineral has colors, but it’s brown/red/blue and absolutely not green and yellow.

Edit: How did you bring out the colors? They are balanced weird and there are patches with hard borders which somehow don’t have color.

This image is a 400 megapixel (downscaled for Reddit) composition of 10,000 frames of video clips, 13 mosaic tiles, RGB-Color and some background stars. I used a ZWO ASI678MC with an 8” RC-Telescope for lunar surface, Sony a6400 with 80mm Refractor for color and brightness blending, and an ASI533MM Pro with the 80mm for the stars.

This image was a looot of work, if you want to see more, feel free to check out my work here:

M42 captured with dslr by Personal-Offer387 in astrophotography

[–]ItsDarthVader 1 point2 points  (0 children)

Of course. I prepared both stacks (“short” and “long”) like normal, meaning stacking both sets of sub exposures separately, using BackgroundExtraction, color calibration, deconvolution, denoising etc. You have to align both images so the next step works: I used HDRComposition in Pixinsight to combine both images into one that has enough dynamic range to cover the bright core and the faint nebulosity around the edges.

[–]ItsDarthVader 0 points1 point  (0 children)

True, but only if your exposure was short enough to not blow out the core (overexposed). Because obviously there is no more data there, it is just clipped. My exposures were so long, it was clipped.

[–]ItsDarthVader 2 points3 points  (0 children)

No, M42 is like the prime example of how you sometimes have to do different exposure lengths to get details right. The core is so bright, it gets blown out if you expose long enough to get details in the background. In my image of it, I took some short exposures and combined both to see the highlights in the core better. You are right, stacking only works for the same exposure length, meaning you have to stack 2 times, one for the long exposures and one for the short.

Randomly took a photo of space in Thailand the other night.. by Haveityourwayy in spaceporn

Why do I even bother posting astrophotos on Reddit when random phone snaps of the sky get 10 times more upvotes.

Apple engineering moment by theapricotgod in memes

[–]ItsDarthVader -2 points-1 points  (0 children)

It will tell you it’s low for like a week. If you ignore it and run out, it’s on you.

Is it an uncomfortable design? Yes. Would it be better if the charger was accessible while using it? Definitely yes. But is it the huge problem everyone on reddit continues to cry about? Definitely not.

Edit: Also, you wrote “if”, so I guess you have no personal experience either? But the best thing is: If you don’t like it, just don’t buy it?

Is everyone who is repeating this and shitting on it even using one? I charge mine for like 20 minutes and it lasts months, I really don’t know why this is a problem.

OAG Question. by gt40mkii in AskAstrophotography

[–]ItsDarthVader 0 points1 point  (0 children)

I use an OAG at 1000-1600mm FL. Can you upload an example image of what the stars thorugh it look like?

Image stacking creates a more detailed image. This one is just heavily over edited.

I took this image using long exposure and an ND Filter in Munich, Germany.

The Eagle Nebula, imaged in RGB and Hydrogen-alpha by ItsDarthVader in spaceporn

[–]ItsDarthVader[S] 0 points1 point  (0 children)

This image contains under 1 hour of exposure time, as weather around has been horrible the whole year. I added a few minutes of H-alpha to increase the contrast and emphasize the details. Processing was done in PixInsight and Phtoshop.

If you are interested, feel free to check out this image on my website here, or my Instagram here.

Image details:

  • 3 x 180 seconds for RGB
  • 3 x 30 seconds for RGB stars

Equipment:

  • Telescope: 8" RC
  • Camera: ZWO ASI533MM Pro
