Yes is back after a 3 year break.

2021 Orion nebula. Istanbul, Turkey.

This is more of a technical limitations exercise. It is shot with a sony a6000 and my trusty 135mm Samyang.

Supersampling is used with 21 frames, to reduce noise and increase the resolution. (this is a cropped detail)

The limiting factor here is light pollution more than anything.

Is that CC 4.0 International?

There are so many versions of it…

I thought it would require a link to the legal text to count 🤔

@RyunoKi
caveat of not a lawyer etc,
edit: yes it is 4.0 international. (completely wrongly parsed that question) xD I think by default newest one is assumed unless otherwise defined but should probably clarify

you do not need to link the full text in every toot in a microblogging structure I think. (I do link it in my website)

@eylul
2.1 was popular for a while, too (Flickr…)

But Cory Doctorow pointed out that it can be used to extract money from users.

@eylul Samyang lens are really luminous, and they was affordable in regards of their quality few years ago. I didn't thing it was possible to see this inside a city ? I remember to have seen one time the really luminous real sky in far countryside. Colors and density is really impressing. We really miss a lot with our lights.

@popolon
samyangs prioritized optical quality and kept them down with tradeoffs like weight and being fully manual (they moved away from the latter since and are more expensive since)

@popolon
it was an usually luminous sky (we get them sometimes in winter) but quite honestly I was surprised it worked. I know for a fact that milkyway doesn't. (although I have some ideas to try there)

I think one advantage is that orion is very bright. its just a bit small to notice with naked eye

@eylul have you played with siril.org? I have yet to try but seems nice.

@piratenpanda
I have and totally intend to go back to it.

My experience was that at the time it didn't deal with lens distortion as at is designed for more photography through a telescope. This was years ago though and I know they have added tons of features since.

its on the todo list.
