Gravitational lensing in abell 2218
Equipment
Heq5 pro mount
660mm fl 102 ap scope
240mm fl 60ap guide scope
Asi533mc pro camera
Asi185mc guide camera
Asi air plus
Uv/ir cut filter
Processing
60x300s frames from bortle 4 75% moon
Plate solve
Spcc
Graxpert background removal
Seti astro sharpen
Gradient correction
Generalised hyperbolic stretch
Black point stretch
Extract luminence layer
Generalised hyperbolic stretch
Invert colour
The green circles on my image show where I believe I have captured gravitational lensing the red circles show where I could’ve possibly captured gravitational lensing however I am unable to determine whether it is lensing or noise.
The blue circles on my image show reference point where I have overlaid my image with the Hubble’s image to determine whether or not I have captured gravitational lensing. All of these circles will be marked on the Hubble’s image to show where I believe I have got the lensing.
This image is extremely cropped as it appeared extremely small in my field of view. The galaxies in this cluster are 2.3 billion light years away and the galaxies that are shown by gravitational lensing are 8 billion light years away from Earth.
The uncropped image will be linked in the description.
