Hello Astronomers, As I'm still slowly processing my remaining data captured earlier this year, now I'm sharing with you my image of the Lagoon Nebula exposed in narrowband Hubble palette. To me, the shape of M8 in narrowband resembles the map of Australia... This image was also in the group of captures in exposing the Prawn, Lagoon and Swan nebulae on the night of 5/6 July in OSC natural color. As with the Prawn and Swan nebulae, I decided to spend a few nights capturing SII, HAlpha and OIII data of M8 also, spending 1/3rd of the night imaging time on each of the objects, this way I ended up with data of all three at the end of the imaging sessions. This image was exposed through my Bosma 80mm refractor and the full spectrum modded Canon 40D on nights from 6th till 19th July 2019. The total exposure for all three channels of this image was 1002 minutes. Thanks for looking, Clear skies Mariusz
The Lagoon Nebula ( Messier 8, NGC 6523 ) in the constellation Sagittarious. ( click on image to see larger) The Laboon Nebula ( M8 ) is visible to the naked eye under dark skies from most latitudes except the far north. Seemingly covering an area about three times that of the full Moon, M8 actually covers an area somewhat greater than 110 light years and is around 4300 light years from Earth in the Sagittarius-Carina spiral arm of the Milkyway galaxy. ...... The frames for this image where taken back when I was very new to astrophotography and I was experimenting with camera settings. On this occasion I wanted to see if JPEG images might be easier to process - I was disappointed with the results. Now that I have a bit more knowledge and skill at processing I decided to have another attempt at trying to process the set because I liked the way the JPEG files had retained colour in the stars. I am reasonably pleased with the result; the faint detail in the nebula is not there but I quite like the colours in the centre and in the stars.
