Astrophotography - Narrowband

*************** NABULAS ***************** -----
False colors ------- Most of the images here are false colors but are based on the same Hubble color palette using narrowband filters Sii (Sulfer 2), Ha (Hydrogen), and Oiii (Oxygen 3). Although the colors are false it clearly shows Sii as red, Ha as green, and Oiii as blue colors - yellow is a mixer of Sii and Ha.

NGC 3372 aka ETA Carina The Carina Nebula (also known as the Great Nebula in Carina, the Eta Carinae Nebula, or NGC 3372) is a large bright nebula that surrounds several open clusters of stars. Eta Carinae and HD 93129A, two of the most massive and luminous stars in our Milky Way galaxy, are among them. The nebula lies at an estimated distance between 6,500 and 10,000 light years from Earth. It is located in the constellation of Carina. The nebula contains multiple O-type stars. This nebula is one of the largest H II regions in the Milky Way. It has a visual magnitude of 1.0. The astronomical coordinates are: R.A.: 10h 43.8m Dec.: −59° 52' The nebula is one of the largest diffuse nebulae in our skies. Although it is some four times as large and even brighter than the famous Orion Nebula, the Carina Nebula is much less well known, due to its location far in the Southern Hemisphere. It was discovered by Nicolas Louis de Lacaille in 1751–52 from the Cape of Good Hope. ************************************************************************* Processed using HST palette Red=SII Green=Ha Blue=OIII. ************************************************************************** Captured using: Camera: OSC QHY8 as main and QHY5 as guide| Filters: SII 8nm (23x20min), Ha 7nm (4x20min), OIII 8.5nm (6x15min)| Captured using Nebulosity 2 and PHD for guiding| Scope: WO FLT-110 Triplet f/7| Mount: HEQ5 Pro| Processed: IP v3.75|

Taking a closer look at M16 using telescope with a focal lenght of 1625mm, apertureof 203mm and focal ratio of f/8 compared to previous image which was taken using telescope with a focal lenght of 770mm, aperture of 110mm and focal ratio of f/7. ********************************************************************************************* M16 (Eagle) Nebula in narrowband. The Eagle Nebula is estimated to be 7,000 light-years from the Earth. In the sky of Earth, it spans to a dimension of 70 by 55 light years, the famous Pillars of Creation is around 7 light years in height. ********************************************************************************************** Processed using Hubble palette Sii=Red, Ha=Green, Oiii=Blue ************************************************************************** Captured using: Camera: QHY9 mono as main and QHY5 as guide| Filters: Sii 8nm (9x20min BIN2), Ha 7nm (17x20min), Oiii 8.5nm (6x20min BIN2)| Flattner: MPCC| Captured using IP and PHD for guiding| Scope: GSO RC8 f/8| Mount: EQ6 Pro| Processed: IP v3.82 and PS-C3|
