NGC i IC objekti

[kruska]

Prvo da kazem da je slika odlicna.

Treba odvojiti vreme za obradu Pelikana jer je tu celo vidno polje slike 100% za obradu u gomili tamnih elemenata prasine i zvezda.

Super slika.

NGC 6888, Caldwell 27, Sharpless 105  (ipak slika ide u NGC i IC objekti)
Crescent nebula
30.06.2025.  i    1.07.   2025.
Previse sam puta slikao ovaj objekat i malo sam se zasitio istog tako da "samo 3h materijala"
i drugi objekti da dodju na red

RC8 f1245mm f6, ASI533MC, Eq6R, guidescope 200mm
L-quad  RGB     30x120s    1h
L-para  HaOIII  60x120s    2h
darks, flats, biases


Pixinsight, skoro pa osnovna obrada.
P.S. za nekih 20 dana cu 4 h dual band HaOIII snimiti

NGC5432, Cat's eye nebula, Caldwell 6

"The Cat's Eye Nebula (also known as NGC 6543 and Caldwell 6) is a planetary nebula in the northern constellation of Draco, discovered by William Herschel on February 15, 1786. It was the first planetary nebula whose spectrum was investigated by the English amateur astronomer William Huggins, demonstrating that planetary nebulae were gaseous and not stellar in nature. Structurally, the object has had high-resolution images by the Hubble Space Telescope revealing knots, jets, bubbles and complex arcs, being illuminated by the central hot planetary nebula nucleus (PNN).[3] It is a well-studied object that has been observed from radio to X-ray wavelengths. At the centre of the Cat's Eye Nebula is a dying Wolf–Rayet star, the sort of which can be seen in the Webb Telescope's image of WR 124. The Cat's Eye Nebula's central star shines at magnitude +11.4. Hubble Space Telescope images show a sort of dart board pattern of concentric rings emanating outwards from the centre. "

Moj prvi "megadata" projekat. 7 noci snimanja, 685 minuta (11.6 h) signala u OIII, 515 minuta u H-alfa (8.6 h), nekoliko poduzih AVI za centralni deo planetarnom kamerom (224MC) sa Barlowom.
Jos par dana CPU vremena, Autostakkert je obradjivao AVI skoro pola sata (na 5.6 GHz Ryzen 7 7700X sa 64GB RAM i 2TB Samsung Pro fast SSD).
Na zalost, transparentnost kao i seeing letnjih meseci nikad nisu nesto posebno, tako da je i rezultat donekle ispod ocekivanja. Svejedno, ASTAP je pronasao gomilu PGC objekata.

i na kraju ASTAP (LEDA database) identifikacija objekata

Odličan! I dobar podsetnik da je sledeći put probam i sa OIII filterom za halo, koji je ovde praktično dupli.

Meni ovo fenomenalno.
