Description

M45 with Interstellar Medium

This is a wide field shot using 135mm camera lens with DSLR. ISM (Interstellar medium) became more visible when enough integration time at a darker site. 

Camera: Canon T5i (Self-modified)
Lens: Oshiro 135mm (at f/4)
Tracker: iOptron Sky Tracker Pro
Exposure: 800x30s ISO1600 (6.7 hours over two nights)

Processing is a bit tricky this time. Starnet++ was applied to the linear non-stretched stacked picture. Stars and Backgrounds with ISM are processed separately. In Photoshop, blue halos around stars are removed carefully. The background layer and star layers are blended carefully to show the dust lines without over-exposing the stars and the cluster.
