How do I make my own SDSS astro gallery?
The Sloan Digital Sky Survey (SDSS) has made considerable effort to share it´s images and data with the general public. The SDSS team went as far as providing many useful online tools for users on their website. It´s not everyday you get a chance to go to a website and grab images from a 2.5 meter telescope that would otherwise cost you many millions of dollars to put in your own backyard. The index images on this website provide a way to locate the larger objects in the SDSS survery area of the sky. This direct link to M86 and its surroundings is a good start.
