Image Description and Details : Messier 97 - a planetary nebula in Ursa Major sporting its faint OIII Halo. It is approximately 2,030 light years from Earth.
I was pleased to be able to tease out some of the structure of the faint outer OIII halo - especially as most of the OIII data was captured from my Bortle 8 sky in London because Spain has been clouded out for the past month.
Image captured on my remote dual rig at Fregenal de la Sierra in Spain and my C11 telescope in London between 14 January - 24 March 2022.

Image Description and Details :

A classic of the spring sky: the duo of the galaxy M108 with the Owl planetary nebula (M97) in Ursa Major.M97 is 2000 LY away, while M108 is 32 millions LY away (16.000 times more distant).I completed the LRGB with exposures with Ha and especially OIII, in order to gain signal on M97: the much more faint outer ring of M97, not so often seen, is visible.Takahashi TSA102 - AZEQ6 - Atik Cameras AtikOne 6.0 - Filters Astronomik (6nm Ha / OIII)L : 36 x 600s bin1RGB : 3 x 24 x 300s bin 2Ha : 12 x 600s bin 1OIII : 18 x 600s bin 1 + 12 x 600s bin2Total : 19h3, 4 & 5 april 2021 - Fouras (France)Traitement : Pixinsight & Photoshop
