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.
Mis-labeled galaxy - M53
In map 13, in the constellation Coma Berenices, M53 is labelled M35. You might want to update that. I’m pretty sure it’s an error.
United StatesDoes not work with most updated OS
I really was excited about this for my observational field needs as I have the hard cover book versions or Mr Tiron's maps but it has too many glitches under the latest OS on the IPad. For one, you cannot set the settings bars to display messier and deep sky objects. The program allows you to toggle the switches but once you move back to the maps, the setting reverts and no deep sky objects appear on the maps. I would give it more stars if this is fixed
United StatesTelrad Finder
The app is great, but it would be nice if one was able to turn on a bullseye very much like the Telrad and able to move that bullseye to the target you looking for. With the bullseye on the map and the bullseye on the ones Telrad-Finder it will help one have more of a perspective of where the object are in relationship to the map and in the sky. See I have the spiral bound Sky Atlas 2000.0 by Wil Tirion that's 22" X 14" and it came with a acrylic Device that has Star Magnitude, Degrees and micro-find-glass bubble and the important one is the Telrad Bullseye, with the Bullseye option I'd give it 10 stars. Note the Objective is that you can turn on the bullseye then put your finger on the bullseye and drag it to that Galaxy, Nebula, Globular Cluster, place it on that target then on looks though the Telrad on ones telescope look at the chart and compares what you see on the chart to the sky. Oh yes and able to control brightness of the bullseye as well. Thank you.
United StatesGood But Could Be Great
This is a good basic star chart, not Uranometria but OK. A few improvements could make it great: 1. Field of view circles. 2. Option to display mirror image view seen through a scope. 3. Slider to change faintest magnitude displayed. 4. Controls on screen not buried in a menu. 5. Stars to magnitude 8 or 9.
United StatesBest of the star charting programs
Easy to use and best quality charts
United StatesChart 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
United StatesOK, but cannot replace the real book.
Need a way to tell the exact RA and Dec by touching the screen, and a way to put field of view circles or telrad circles on the chart.
