Night Sky Guide

Night Sky Guide is a field guide to find the planets, galaxies, nebula, star clusters and other deep space objects.

It is designed to help you be successful in astronomy events such as a Messier Marathon, completing an observing program, or just out enjoying an evening with your telescope.

By knowing, real time, which DSO's are above and where they are in the sky, you can spend less time looking at lists and more time viewing. The many display options help ensure you don't miss out on seeing that favorite galaxy or nebula!

Features:
* - Includes 1,570 Deep Space Objects, including all DSOs in the Pocket Sky Atlas
* - Includes the planets and the Messier, Caldwell and Herschel 400 lists
* - Works as a real-time observing list, letting you know what's in the sky above
* - Provides up-to-the-minute altitude and azimuth and rise/transit/set times
* - Constellation maps and page numbers for common sky atlases
* - Easy-to-use viewing list plus detailed info for each DSO
* - Includes the ability to search by name and object identifier
* - Sort and display options to prioritize your viewing order
* - Observation log to keep track of your progress
* - Ability to export your observation logs and track your progress
* - Use GPS or define your own viewing locations

The Messier objects are a collection of 110 galaxies, nebulae and star clusters that are popular targets for amateur astronomers of all experience levels and binoculars or small telescopes. The Caldwell list includes 109 deep space objects and is a great next step after the Messier list. The Herschel 400 provides an even greater challenge for observing deep space objects.

The Astronomical League sponsors observing programs for the Messier, Caldwell and Herschel 400 objects. This app was designed to help you successfully complete any of these programs.

Even if you complete all the observing programs, with 1,570 objects in the app you should be able to enjoy years of searching the night sky.

Night Sky Guide can be used standalone or in conjunction with a sky atlas to star hop your way around the constellations. Spend less time trying to decide what to observe and more time observing!

Plus, Night Sky Guide is completely free, ad-free and open source!

I can see this app being very useful. The fact you can choose not to display objects you have already logged helps you concentrate on new targets. When opening the app it displays what's currently visible and its altitude with lots of filters to suit you sky conditions, a simple but very effective app.

I have been looking for a loggin app for Astrophotography, it almost has all, maybe make another app where we can log very detailed info, stelleriums, stacker, all filters used which telescope was used etc. so we will have it for a resource and reference, it will be half filled in instead of having to log the same things over an over the only difference is the target, filters, etc. If there is one out there I have not found it

It looks like a great app, but it puts me in the southern hemisphere and I can't find a way to fix it. When I select my devices gps it puts me in a negative latitude right number but a negative.

The planet names are not on the graphic. I don't know what the symbol is that represents the planet so it did help me one bit.

Considering how many stars are on the more...I give it one

Horrible. Doesn't even. Deserve 1 star

Big database with ability to log your efforts. Good app so far. Does need a red light feature for field work.

I can navigate better in old paper star maps than this... Thanks but you can have these bunch of numbers for yourselfs. Enjoy living in your own parallel univers

Just Rows of numbers .only good if you new all about it anyway

To dumb to operate it

I think i'm the 2nd person to ever download it, which is weird af. Despite that, i think this is my favorite star app, no bs. I've downloaded every single one of them, trashed most, kept 4, plus this one, and yeah - so far this is my favorite. It's basic enough to be intuitive and complex enough to get super detailed without bogging you down.

Very good app just wished it had a night mode like red to use while out stargazing, light is our enemy

I really like this app but I only gave it 4 stars. It would be nice to be able to change the date and time for planning events like Messier Marathons. Include the entire NGC catalog and I'll give it 5 stars.

I don't have a telescope and am not into astronomy but wanted to look at your app. It's very well done. I'll share it with people I know who enjoy this stuff.

Really excellent app... I was just working up the courage to write something to do exactly this. All it needs is a larger database of DSOs (or the facility to import your own database?), and maybe a red-filtered mode.
