ACO 2218 - Gravity Lens w/ HST ref frame

Technical card

Resolution: 421x418

Astrometry.net job: 1223921

Description

The gravity lens created by the large galactic cluster Abell 2218. The HST image shows where the lensing freatures are.
Scope: iTelescope SRO42: 24" Planewave in Calif.
Exposure: 19x10'Frame size: ~260" across (~1.5% of full frame)
Processing: PixInsight
Animation: CS6

Abell 2218 contains ~10,000 galaxies as well as a large mass of
dark matter, all of which contribute to the lensing effect.
The faintest objects in my image are below mag. 20. Please excuse
the dark ringing; hit the decon quite hard to emphasize the
gravity lensing!
