M57 Ring Nebula from Peckham with 80mm refractor (Zoom in if you can to see the ring)
Just trying to see how far I can push my pushing my 80mm apo refractor in London light pollution. I didn't think this scope could resolve the donut shaped nebula but I was pretty chuffed to see it can...hope you can see it? It is small, granted. Zoom in if you cant.
So this is a planetary Nebula. The remnant materials shed of a star that came to the end of its main phase of life. In much much larger telescopes, a white dwarf lies in the centre. I previously images the dummbell nebula which is a similar planetary nebula but with a "side on" perspective compared to this nebula we observe "top down" perspective.

Capture details
-------------------
Location: Peckham, London, Living Room window!
Telescope: 80mm Equinox APO refractor with a field flattener
Mount: Nexstar 6/8SE Alt Az on a sturdy table.
Camera: Canon 650D unmodded
No filters used
Light frames
557 X 5 Sec ( 48 mins)
ISO 1600
32 Dark Frames
Stacked with DSS (Deep Sky Stacker). Manually adjusted RGB levels, luminosity and saturation to get as visually appealing image with colour stars before importing into imaging software.
Camera Raw: slightly cropped, adjusted black, and curves
Photoshop. Violently, clipped dark side information to eliminate colour noise . gradually adjusted levels multiple times to eliminate light pollution, curves to bring out more detail.
