Gallery of  "Extragalactic Objects Within Host Galaxies" imaged with my 12" LX200 telescope and ST-10XME Camera (2020-2026+)

Project was inspired by Alvin Huey's guide book "Observing Extragalactic Objects Within Host Galaxies" (on www.faintfuzzies.com) with 158 host galaxies with observable extrgalactic objects.

	NGC 7331 - Spiral Galaxy with H II Regions & Type Ia SN
	NGC 7479 - Spiral Galaxy (Caldwell 44) with H II Regions and Type Ib SN
	NGC 7678 - Spiral Galaxy (ARP 28) with H II regions
