SIRIL - Besplatni program za stakiranje i osnovnu obradu astro fotografija

[Ryukote]

Pozdrav svima,

vidim da nema teme za Siril, pa bi ja htio otvoriti sa pitanjem da li netko zna neki popis open source skripta za Siril (ako postoji) koji naravno ne dolaze uz sami Siril.
Ovo https://github.com/lolotux69/ScriptsSIRIL je sve što sam na Github-u uspio nać.

Hvala

Jesi li kliknuo u programu na "get scripts"? Meni se ove dvije skripte čine iste kao ono što se službeno nudi ovdje: https://free-astro.org/index.php?title=Siril:scripts dakle verzije bez flata i darka.

[Ryukote]

Cool, za ovu foru nisam znao  Tnx

[Astrobobo]

Dosta dobra fora je ovo sa korekcijama pozadine na svakom pojedinačnom frejmu.

To bi trebalo biti dobro ako imas uličnu lampu u blizini, pa se LP u biti pomalo pomiče i nije konzistentan kroz slike. Super stvar u teoriji.

Ili kod širokokutnih ako se snima cijelu noć.

Jučer sam pokušao nešto stackirati u Siril-u kojeg već dugo koristim ali sam imao problem.
Kada sam pokušao pre-procesurirati flat frameove došla mi je greška "siril not using offset image dimensions are different"
Nije mi se to nikada pojavilo. Ponovno sam snimio flat-ove pa bias frameove, i iz nekoliko pokušaja sam uspio.
Nakon toga kod preproces Light-ova nije htio otvoriti masterFlat, ali je opet uspjelo nakon natezanja nekoliko puta.
Je li netko imao sličnih problema?
Za akviziciju koristim NINA.

Pitam jer do sada nisam imao nikakvih problema i ovo je prvi puta. Tako da mi stvarno nije jasno zašto..
Možda je to neki novi update softvera pa ima kakvu grešku...

[tome]

Evo da malo osvježim temu.
Čini mi se da nije bio problem u Siril-u već u NINA-i. Naime treba paziti kod odabira kamere koji se driver koristi.
Moju kameru mogu koristiti preko ASCOM drivera ali i preko nativnog Omegon drivera. Ne znam zašto ali dimenzije snimke su različite za nekoliko piksela i to stvara probleme kod kalibracije.
Mislim da je to bio problem..

Pa eto ako još nekom dodje da sve baci kroz prozor i počne se baviti nekim hobijem u kojem nema softvera, nek provjeri koje drivere koristi....

Hvala tome, ovo je itekako korisno za znati

Lagano se probija kroz žbunje ovaj mali i poprilično dobar program za stakiranje i obradu astro fotografija. Realno stariji je od Pixinsighta i kao početnički program za stakiranje i obradu odlično se snalazi među onima koji su se tek dotaknuli astro fotografije.

Velika prednost mu je što je besplatan i nudi osnovne alate za obradu koji su sasvim pristojno napravljeni. Između ostalog konstantno se nadograđuje novim alatima i lagano postaje nezamjenjiva alternativa plaćenim programima. Gotovo da je zamjenio Deep Sky Stacker za stakiranje a također ima RBF algoritam za skidanje gradijenata koji još ne postoji u Pixinisght-u.

A di je nesta Siril (https://siril.org/) vec nekoliko dana pokusavam otvorit tutorial meni ne otvara...

Izašla je nova verzija 1.2.0 beta. Iako je beta tretira se kao nova verzija Siril-a.

Pregršt novih opcija je od sada na raspolaganju te se i dalje bugovi mogu prijvaljivati na gitlabu.
