Date image was taken: July 15, 0202

Location (was image taken with remote scope?): High Atlas Observatory (Oukaimeden Observatory - Morocco)

Image Description and Details: Here's a wide field showing globular cluster M15, planetary nebula NGC 7094 and for the first time visible a large [O III] zone of unknown nature around it. There's also a lot of Hα and cosmic dust.

Acquisition:
July 5 - 15, 2024

Integration (61h50'):
Hα: 177×300″(14h 45′)
[O III]: 375×300″(31h 15′)
L: 205×120″(6h 50′)
R: 90×120″(3h)
G: 90×120″(3h)
B: 90×120″(3h)


This is an extended structure with a dimension of 1x1.25°.
The [O III] nebula appears rather diffuse, with two band-like structures to the east and west. As cosmic dust covers the structure, we can assume that the [O III] nebula lies behind it, but in front of the fine Hα emissions. The nebula is extremely faint and could only be made visible using special techniques. Without these techniques, the [O III] emissions would have little or no separation from the cosmic dust.
