Description

Leo triplet Luminance layer processed with PI and photoshop CS6. It's a combination of a wide field of view captured with Canon lens 200mm @ f/2.8 and a closeup view of the Leo triplet captured previously with my APO refractor TS 80/544 mm(capturing details: https://www.astrobin.com/mnlsw8/B/?nc=user). To do an accurate scaling and alignment I used ImageSolver and MosaicByCoordinates scripts from PI.

Faint I.F.N.(Integrated Flux Nebula) are just emerging from the dark background.

Tidal's trail of ngc4438 is also visible.

Asteroid (86) Semele is also visible with 14.09 magnitude on a new revision thanks to Pixinsight solving tool
