NGC 55 Galaxy in Sculptor

NGC 55 in Sculptor (APO120 Ra).jpg

Add to Cart Add to Lightbox Download
This is the large (1/2º across) and bright (8th magnitude) edge-on galaxy NGC 55 in Sculptor. It is one of the brightest members of the Sculptor Group of galaxies near the South Galactic Pole, though some consider it a member of our own Local Group. It exhibits an asymmetrical shape and is crossed by dark dust lanes. It is classed as a barred spiral, though that is hard to discern here with its edge-on orientation.

The field of view is 3° by 2°.

Technical:
This is a stack of 16 x 4 minute exposures with the Askar APO120 refractor at f/5.6 (with its 0.8x Reducer) and the Canon Ra at ISO 1000. Taken from the Quailway Cottage in southeast Arizona in October 2024, with this field low in the south.
