Image Description and Details: SNR G132.7+ 1.3, also known as ‘HB3’, is one of the most extensive supernova remnants in our galaxy, measuring around 1.5°x2.0°. On the other hand, its luminosity is quite low, especially in the Oiii, so much so that we had to spend around 140 hours in total (LRVB-HOO) spread over 2 tiles of 70 hours each. This is our longest project to date with the AAA team. The first papers on the discovery of this X-ray signal date back to 1980.
Alongside the Heart Nebula is IC1795. Also known as the Fishhead Nebula, it is an emission nebula located around 6,000 light-years away and was discovered by the American astronomer Edward Barnard towards the end of 1890. This area contrasts sharply with the rest of the image because it is very bright and appeared almost overexposed when it was stacked.
