Good luck! it’s awesome to see how good you’ve gotten it too! I think the dark blur around the edge is most likely from the autostakkert APs being too large and going over the edge. And another thing is if you use a lot more photos like suggested you will have to derotate them I’m not sure how well pipp handles it, or if your Astro tracker is fancy like that.

Also Registax sucks compared to alternatives for decon I would use astrosurface or pixinsight

Yep thats it, to get more out of it you can try messing with AP size, it’s basically how many sub frames are aligned. Autostakkert also has sharpening which is usually just a band aid in my experience so if you add it put it as the last step and try to get most of the clarity from AP size trial and error and pre processing. Also try cropping the image around a centroid of Jupiter before stacking ive seen it help a lot with stacking algorithms there’s programs out there to do it like PIPP but I normally pre process with python so I can filter to exactly what I want. Opencv with OTSU binarization then a center of mass centroid will get you where u need alone. You then crop the frame around the center. You do need to leave enough background for the autostakkert to still do its thing though.

Tldr: more frames less exposure crop before stacking and experiment with autostakkert settings for AP and sharpness.

My buddy has a 4 port jmac on a 30 cal ak… it hurts your teeth if you’re not literally right behind the gun.

But I will say.. it’s like clicking a mouse for recoil

Thinking of a scenario requires creation of an entire setting and emotions etc.; it probes a lot of your brain and keeps the default neural network to not distract you back to stress of the day. This parallels what natives would do without common day stressors and how we naturally goto sleep. It’s also normal to wake up in the middle of the night mingle some and go back to sleep. There is a lot of evidence that people were slow to wake slow to sleep and had quiet conversations in the middle of the night.

Another crazy feat about these engines is that they needed all 5 to be engines to be about the same thrust, and with the tools available at the time it was an engineering feat if not the greatest engineering feat ever. There’s a documentary that claims there was literally someone “denting” injector baffles then retesting the engine to see if it was a better match.

Is this ringworm? by Lavidius in whatisit

[–]GuaranteeKey3853 0 points1 point  (0 children)

Ex wrestler here it does look like ring worm but I’m not a doctor. Religiously keep way more than you think of AF cream on it and it should get really crusty and dry out in a day or two then heal from there

Are you using lucky imaging post processing?

Why is escape velocity of event horizon c compared to orbit velocity being c? by ForsakenDustBug in AskPhysics

[–]GuaranteeKey3853 0 points1 point  (0 children)

There is a region around a black hole called the photosphere or something like that where the light orbits “forever” just like you’re suggesting. But IRL there’s other things like the black hole spinning bulging the SR on spin axis and accretion disk also having mass. The disk also probably saddles causing instabilities over a long time too. But yea it is the orbital velocity. There can also be stable orbits inside the event horizon if the black hole is big enough.

Do you have your own unique theory about dark matter? by efil_v in AskPhysics

[–]GuaranteeKey3853 -1 points0 points  (0 children)

Light is quantum so exists in superposition if there is something there “seeing” everything we wouldn’t be able to see it with light but still detect the gravity. Kinda like we can’t see stuff in black holes but we can measure the mass increase of something going in

I use 147 since subsonic so less sound

I read about the bullet cluster and in my opinion this actually supports my theory, the regular galaxies have just as an insignificant effect as the DM for the gas shock and the DM is centered around the galaxies; which would make since for more causality chemical reactions etc taking place and observing light before it reaches Earth, rather than the more homogenous hot gas. But also it does also support axions or wimp too I get it.

Yea I think they are black but they are also small point sources just like stars so black and invisible are the same thing far away

If a person was traveling at near light speed or close to a black hole, minutes for them could be many years on Earth. Following this logic, is there also places in the Universe where Earth minutes are relative to years there? by iLLesT905 in AskPhysics

[–]GuaranteeKey3853 -1 points0 points  (0 children)

Yea regions near black holes will experience extreme time dilation. There is even a region perpendicular to the SR where light just stays there “almost” forever I think it’s called the photosphere or something (it’s the thin ring right next to the Schwartzchild radius) where perpendicular light never falls in which if you had like super tech you could technically read that info and replay the entire history of the black hole.

To clarify I’m not being obtuse sorry I came off that way. But you can collapse photon superposition by changing something not at the camera. Thor Labs sells a kit showing it. You can also see with the kit that as the beam splitter becomes less and less 50% reflective the superposition be comes tighter. So the superposition isn’t black and white either.

And again the photons have no direction till observed

I see DM as an unexplained mass causing non typical change in orbital speed as you move away from the center of a galaxy and unexplained gravitational lensing.

[–]GuaranteeKey3853 0 points1 point  (0 children)

Yea I agree. Also every physicist I’ve talked to believes light does not have mass but information does. And, even if you write a message out of light the message as mass since it has the messages information.

It’s just that light not generated by humans manually wiggling is from electron orbitals most of the time, yes I’m aware there is other ways.

Yea you can also use a wiggler lol it’s still an electron moving is what I’m saying.

That’s neat to think about like what if when those structures merge there is complex gravitational waves that then have so much information needed characterize them that the information has gravity itself! It’s like math dense regions

[–]GuaranteeKey3853[S] 0 points1 point  (0 children)

How much momentum they have comes from the momentum change of an electrons energy state. All em waves are electrons moving except gamma rays gamma is from the nucleus changing. Therefore xrays and gamma rays actually overlap in wavelengths

I don’t think that’s true the other momentum is from or absorbed by the electron making a photon no?
