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.

Bright Stars

List of Bright Stars (for focus) to 1.25 magnitude
https://en.wikipedia.org/wiki/List_of_brightest_stars

Use these brightest stars that can poke through light pollution when using the Bahtinov mask for focus. Red denotes northern constellations and blue is for southern.
