SNRG65.3+5.7 in HOO with RGB stars

This is four-panel mosaic of SNRG65.3+5.7 in HOO with RGB stars. It is a vast but very faint supernova remnant located in the constellation Cygnus. It has low surface brightness against a crowded star field. First identified in 1977, portions of the remnant had earlier been listed as Sh2-91, Sh2-94, and Sh2-96. Spanning roughly 230 light-years in diameter and estimated to be around 27,500 years old, it rivals the Veil Nebula in apparent size but is far more difficult to observe due to its faintness.
I captured around 169 hours of data across four panels from May to Sept, 2025 from my backyard.

SNR G013.3-01.3 in SHO with RGB stars

Small Sagittarius cloud and the faint SNR G013.3-01.3 is an often ignored area of the summer milky way region. It is located in a very dense star field. The SNR appears as a delicate, fragmented shell of ionized gas - traces of a long-faded stellar explosion. Its subtle OIII and Ha emissions blend beautifully with the rich backdrop of the Milky Way. 
This is SHO representation of this very challenging but beautiful field. It rises just 35 deg over the horizon at my location.

Lagoon nebula (M8) in SHO

Lagoon nebula (Messier 8 is located 4,100 light-years away in Sagittarius. This glowing cloud of gas and dust is a stellar nursery where new stars are born. At its heart lies the young star cluster NGC 6530, lighting up the nebula with intense UV radiation. You can even spot it with the naked eye under dark skies! The dark lanes you see? Those are dense Bok globules—potential stars in the making. A true gem of our Milky Way!
This image highlights the nebula’s bright core and the Hourglass Nebula, a chaotic region shaped by intense radiation from the massive star Herschel 36. The core shines around magnitude 6, but its intricate structure—glowing gas, shock fronts, and dark dust—is only revealed through deep narrowband imaging.
Captured using Celestron 9.25" EdgeHD, ASI2600MM Pro, Antlia 2.5nm SHO filters, and EQ6R Pro mount, with data processed in PixInsight.
