Description

These are serious Star Charts! Not a planetarium-type app suitable for beginners, but rather a very detailed series of charts of the night sky for observers using binoculars or a telescope. Prepared by famous celestial cartographer Wil Tirion, they present the entire sky in the form of 18 charts, 16 covering the equatorial region of the sky (8 each side of the celestial equator) and one for each of the Polar Regions.

Features include:
* Stars down to sixth magnitude; double and variable stars included.
* All Messier objects, plus many NGC and IC catalogue objects.
* Auto detection of your location and presentation of the chart containing the sky directly overhead.
* Choice of positive charts (white on black, recommended to preserve night vision) or negative (black on white – easier to read and better for daytime use.)
* Charts can shown north up or south up to match your location.
* Search charts by constellation or major star name.

Basic default maps show constellation names, constellation lines and major star names only.
Extra layers can be added to reveal:
* Constellations boundaries for all 88 constellations.
* Grid lines and co-ordinates for every hour of Right Ascension and 10º of Declination.
* Star numbers and deep sky object names.

Chart app

Will's app does not work well with OS 6.0.1 I phone. I do think his printed charts are among the best. I hope you can correct the problems BTS

Just Ok - Could Be So Much Better

I think for basic star charts, which is what these are, no more no less, $3.99 is excessive. For star charts, I prefer Star Atlas (which unfortunately is an iPhone app and not universal) which has greater functionality and is currently free (even when it wasn't free it was only $ .99). For example, in Star Atlas, you can search by Messier Number, or Constellation Name and when you select the item, the appropriate chart will automatically be brought up on the screen with the desired item centered!

Decent

I think the idea of an app that enables you to choose a particular chart is great, and the credentials of the people involved cannot be doubted. Charts seem to be well executed.

One small critique, and I have this same one for most astronomy apps, the red filter should be right on the main screen like SkySafari does. Not buried in a menu. Give me a button to choose right when the app opens. It's just something that bugs me.
