NGC 7635 The Bubble Nebula in SHO
I have added Sii and more Oiii narrowband to an earlier image of this shot in HOO + L and RGB for stars. The longest capture time for me so far totalling 35.5 hours,.
The Bubble Nebula is 7 light-years across – about one-and-a-half times the distance from our sun to its nearest stellar neighbour, Alpha Centauri – and resides 7,100 light-years from Earth in the constellation Cassiopeia. For perspective, I worked out that it would take a Voyager Spacecraft about 140,000 years to travel across the Bubble Nebula.
Ha, Oiii, LRGB 6 to 10 August 2022 -Moon 50% to 96% but nice and low and setting during the sessions. Sii and more Oiii 21,22,26,31 August 2022 - Moon 29% to 18%.
