Observing deep sky objects with small telescopes presents new and seasoned amateur astronomers a place to log their observations and share information about naked-eye, binocular and small telescope astronomy. So, what’s 90mm all about. Simple really. 90mm is of course the size of my telescope, a Meade DS-90 with Autostar. Most of my observing is done with this instrument. I also use a pair of Meade 7 x 35 binoculars as well as naked eyes. There are many interesting events that take place that can be observed with just your eyes and a pair of good binoculars. In fact, this is a good way for beginners to gain knowledge about the night sky.
