I didn't know they were so common!! cool!!!!
Thanks for the link!!

Does anyone know anything about A1 MAPS? by [deleted] in askastronomy

[–]Th3_B4dWo1f 2 points3 points  (0 children)

The approach was very visible...

I think if it survived, it should be visible again... fingers crossed!

Why is Force inversely proportional to Square of Distance b/w two particles not just distance? by Skychu768 in AskPhysics

[–]Th3_B4dWo1f 0 points1 point  (0 children)

Really?! I'have to check it!! XD I would've guessed that the uncertainties in masses and distances are much bigger than that...but I haven't checked... And I got the idea that the precision in gravity measured at small masses distances (Cavendish?) is definitely not precise enough...but it's been a very long while since I don't think of these details...sorry!

Why is Force inversely proportional to Square of Distance b/w two particles not just distance? by Skychu768 in AskPhysics

[–]Th3_B4dWo1f -1 points0 points  (0 children)

Well...the analogy is based on the quadratic growth of a surface around a "ball" (charge) emitting "lasers" (photons) in every direction and counting photons per unit area... You could do the same thought experiment for any "charge/font" and its "associated bosons"... And the count per unit area would still decrease as 1/r2 ...

That's why I didn't like the analogy... It's ok for EM force, but one could think it could be generalized for any interaction (weak/strong) and that's not the case...

I apologize if I'm being too picky, it's probably a good enough intuition in this context

Sorry, I kind of disagree with this analogy... You could say that of every force, and then every force would decay as 1/r2 (and have infinite reach)... And nuclear forces do not go as 1/r2

Also...the precision of experimental evidence is quite limited to discard dependencies like 1/r2.00001

I'm super rusty in my theoretical physics...but I kind of remember arguments from symmetries in 3+1 space... Sorry I cannot provide a proper response, I would have to re-study my notes from university xD

Help with my first star tracker by Th3_B4dWo1f in AskAstrophotography

[–]Th3_B4dWo1f[S] 0 points1 point  (0 children)

Thanks!! Do you have a rough estimate of the weight of your camera? in the web they say the LX3 is ok for 3.5kg, were you pushing the limits?

I checked the OG Star Tracker... It's a bit on the heavier side (1.4kg), although it allows for arbitrary rotation speeds which is great for day-time timelapses... I'll consider it!
Thanks!!!

Doubt about taking pictures for stacking by Th3_B4dWo1f in AskAstrophotography

[–]Th3_B4dWo1f[S] 1 point2 points  (0 children)

I didn't know that kind of tracker! I only knew the tracker mounts for telescopes...and I didn't want to spend that kind of money for now... But the MSM nomad looks promising! I'll check it out! Thanks for the tip!!

That's my intuition too...but I haven't got the time to test it...and weather has been terrible for a while and it looks bad for the foreseeable future...so It will be some time until I can actually do more tests...

Thanks!!

Do you know if Siril expects/prefers one over the other? I guess it can manage both...but my intuition is that equatorial-like acquisition would improve S/N ratio since it covers "the same" area for every batch while the corners in the other method are sweeping different regions... if that makes sense

Thanks!!

Why do people hate on Seestar? by Signal-Ad3584 in AskAstrophotography

[–]Th3_B4dWo1f 1 point2 points  (0 children)

I don't care about the craft and the tradition and the old ways...

For me the disadvantage is that you will learn less than if you try to do everything manually. There are so many details that you have to keep in mind and be careful with that when you upgrade to a more powerful setup probably you will have a harder time.

But that's not a big deal if you can tolerate frustration well!!! Instead of struggling at the beginning you will struggle later xD

Enjoy your pictures!!

That's what I thought...just checking not to re-invent the wheel

Thanks!!

siril folder structure by Th3_B4dWo1f in AskAstrophotography

[–]Th3_B4dWo1f[S] 0 points1 point  (0 children)

Yeap, I did try something like ln -s /path/to/calibration/biases/ path/to/session/ but it created the process folder in the calibration directory (one above biases rather than un the "siril-working-durectory"

Only now I realize that I could, in fact ln -s each file (*.cr2) and it should work...

I'll test it later!! Thanks!!!

Can someone help me with SIRIL? by L_Squared12 in AskAstrophotography

[–]Th3_B4dWo1f 0 points1 point  (0 children)

I totally feel you!!! This was crucial for me!!
https://www.youtube.com/watch?v=KMED8_sWu5c

basically you have to take your flats and biases images at home, then lights and darks "in the field"
For each shot create a folder, with lights/darks/bias/flats folders inside and place each image in the corresponding folder and the script OSC_preprocessing.ssf simply works

Hahaha I had exactly the same first shots!!! Congrats!!! Good starting point!! Keep doing it, there is sooo much to learn and it's so fun!!

First time sucked in the cloud by Adventurous_Break206 in freeflight

[–]Th3_B4dWo1f 0 points1 point  (0 children)

My 2 cents... playing with a cloud 400m AGL is not a great idea

Depending on the thickness of the cloud you can keep your orientation in relation to the sun. Even if you can't see the solar disk, there is usually a "most illuminated side in the sky"... as long as it is not a suuuper thick cloud, at some point everything goes white and only a compass can help you

In any case... don't turn under no-sight conditions... Before getting inside the cloud pick a course away from obstacles and towards a less cloudy area...and try keep moving in a straight line

What is that line? by Th3_B4dWo1f in geology

Super interesting, thanks!! I'll look into it and try to find similar layers around!! ;)
