Bode’s Galaxy, M81, is a popular target for binocular users. You can also catch the Cigar Galaxy, M82, just to its north.

THE DOUBLE CLUSTER (NGC869 & NGC884) as the name suggests, this is a grouping of two-star clusters with stars extremely spread out from one another. This one shouldn’t be hard to find as it’s pretty darn bright! Here is the star map to help you out.You'll notice that this isn't categorized as a Messier object, because it's not! It is still a DSO but is instead a part of the New General Catalog (NGC) listings. The NGC holds over 8,000 objects while Messier has just over one hundred. Neither list necessarily has better objects than the other, and there's no reason to object to one list over another.

The Leo Triplet, or the M66 Group, is a group of interacting spiral galaxies located in the northern constellation Leo. The group consists of the galaxies Messier 65, Messier 66 and NGC 3628, AKA the Hamburger Galaxy! Navigate to Leo and you’ll find the trio, in a common field, near the star Chertan. There are also a few interesting objects nearby. For instance, you may want to try out the nearby M105 and M96.

The Virgo Cluster is one of the grandest deep space objects. Visible from March to July, you can see it throughout spring. And you should make the effort to do so since it packs a few surprises! The cluster, located in the constellation Virgo (unsurprisingly), contains 16 Messier objects, so there’s a real lot to see here. The area between Vindemiatrix and Denebola beside the constellation Leo, lies the Virgo Cluster, as a patch of fuzzy greyness.

If, when you find M20 the Trifid Nebula, you wonder what the smaller cluster on the northeast is, it's M21. So that's another object for you!

EVSCOPE Telescope Tools

The new eVscope is a smart telescope which includes an electronic eyepiece with a OLED, a SONY CMOS low noise sensor and smart software to calibrate the telescope without polar alignment or any of the immense hassles created by other rigs.

EVSCOPE TOOLS
Messier, Supernova, Stars

I've developed some reference tools for getting the most out of the smart eVscope. First up is the main Messier list of all 110 objects. You might want to know when the objects are visible so refer to the list by constellation. For choosing specific types of objects like all galaxies, refer to Messier Objects by type. When dealing with light pollution it's important to know the object brightness - check out the Messier List by Magnitude. For hunting Supernovae, see the List of Supernova, and for calibrating on the brightest stars - a List of Bright Stars is useful.

ON THE MESSIER LISTS by constellation and type, click on the M-number and it will take you to a page with a photo and tons of info.
