Description

Comet 21P/Giacobini-Zinner some days before its maximum approaching. In this full shot of the comet on August 20th 2018 was taken at same time through of TAR2 Telescope in Teide Observatory and my habitual equipment from Hoya Redonda. Besides of the image showing comet appearance, objective of shots were to register internal coma structures using gradient filters. The second version of this image adds graphical wich shows internal coma enlarged and filtered (inverted monochrome) revealing the presence of four jets emerging from nucleus.
