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. ### 4/5 — Decent *2012-08-22* 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. ### 4/5 — Tirion is the master star charter *2011-11-15* Like all of Tirion's work, these charts are very nice looking and easy to read. The only down side is this app seems slower than it needs to be. ### 4/5 — Needs a red (night-vision) mode to be perfect for what it is... *2011-08-24* I like this app a lot, as it does exactly what I want: a quick star atlas without a lot of bells and whistles and settings. However, even the white-on-black "night" mode is too bright in the field and should be supplemented with a red-on-black mode. ### 3/5 — A améliorer *2011-04-22* Effectivement ce sont les cartes célestes de Will Tirion dont les éditions papier se font rares. Mais ici le zoom est très limité et il n'y a pas d'interactivité avec la carte affichée (autant dire que l'ipad ne sert pas à grand chose et est réduit presque au stade de simple viewer type cadre photo). En attente d'amélioration ### 4/5 — Now I won *2011-01-26, version 1.0* This is a good app for its first iteration. 1) It's a little sticky scrolling from a currently displaying map back to the selection page as sometimes you have to scroll past a blank screen. 2) Although the white on black maps are reasonably night time friendly on the field, I'd like to see a proper red-screen mode with all titles and menu items coloured red as well. 3) Scrolling between adjacent maps doesn't really work. If I have Map 10 up for example, with the top half of Orion in my bottom left corner, and I want to scroll to the next map to see the bottom half of Orion on Map 2, a simple flick up on the current map (to move the current map upwards and on to the map below) lands me on Map 18 (Polar North). The gesture direction is reversed, which isn't intuitive. In other words you flick in the direction you want to go rather than displace the current map and bring in the new one. Other than those little nigglies, it's a great addition to my iDevice astronomy collection that I use in the field. ### 4/5 — Top draw *2011-01-16, version 1.0* Just what I was looking for in terms of a Star Chart app. A similar layout to my paper "The Cambridge Star Atlas" also by Wil Tirion, but much more portable. I've only given it 4 stars because you have to load each chart separately, thus splitting constelations. It would be fantastic if you could scroll seamlessly between all of the charts. In summary I would say this is a great app which will get hours of use. ## Most critical reviews (10 lowest-rated) ### 1/5 — Mis-labeled galaxy - M53 *2023-04-14* 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. ### 1/5 — Extremely disappointing *2012-09-30, version 1.1* Some low detail star maps presented in an awkward interface with no context. Compared to some really great astronomy apps out there, this one is extremely disappointing. I'd urge deep sky observers to look elsewhere. ### 2/5 — Does not work with most updated OS *2016-10-03* 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 ### 2/5 — Star charts by Wil Tirian *2011-09-26, version 1.1* I had expected up to magnatude 8 stars like the printed version STAR ATLAS 2000 ### 2/5 — Disappointing. *2011-09-18, version 1.1* When you select a chart it is unusable until you zoom in (on the iPhone). Should show fainter stars. Overpriced. Seems like someone is taking advantage of Wil Tirions good name. I'd recommend Star Atlas instead, it's better and it's free. ### 2/5 — Not Sky Atlas 2000 *2011-03-09* This is a very far cry from his beautiful Sky Atlas 2000! In "white background" mode it presents a visually similar format, but with much less detail. It is, however, a passable basic finder chart. As advertised it present stars to ~ 6th magnitude and some deep sky objects. One significant downside is the cylindrical projection, which distorts the off-equatorial spacing. Since there are fewer pages than I conventional star charts, this distortion is more noticeable. He also basically preserves the original paper chart format, including separate pages (I.e., not a continuous map). If you want an electronic equivalent to paper charts, with significantly less detail than paper, just so you can say you have it electronically, then this is the app for you. Personally, I'm disappointed. Given the integration of computational power, iPad graphic resolution and the beautiful Sky Atlas 2000, this could have and should have been so much more. Maybe in future versions? ### 3/5 — Accurate but clunky *2014-11-17, version 1.2* Would be flawless if we could navigate seamlessly instead of switching manually between maps. There is a constellation index, but if it is placed on a map margin you have to return to the index to view neighbouring constellations. Overall, clunky navigation, there are free apps with star maps out here that are easier to use. ### 3/5 — Good But Could Be Great *2013-09-07* 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. ### 3/5 — OK, but cannot replace the real book. *2012-11-29* 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. ### 3/5 — Just Ok - Could Be So Much Better *2012-01-07* 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! ## Most praised reviews (10 highest-rated) ### 5/5 — Does this work anymore *2021-02-27, version 1.3* Wonderful app, but I haven't used it for several years and now doesn't work in IOS 14.x... need help. ### 5/5 — Wil Tirion star chart *2019-02-05, version 1.3* A good companion to ‘TriAtlas’ which is also available. ### 5/5 — Superb aesthetics *2018-08-02, version 1.3* From the same buggers who did StarDisk. A Norton Star Atlas for my phone. ### 5/5 — Un must *2014-02-08* Une référence pour les astronomes amateurs. ### 5/5 — Best of the star charting programs *2012-12-19* Easy to use and best quality charts ### 5/5 — Chart app *2012-12-18* 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 ### 5/5 — Love it! *2012-07-12* I love this app.. it's a Star Atlas for my iPad.. I use it allot. Being a fan Skalnate Pleso and Tirion this is nice. ### 5/5 — Mr stony *2011-10-21, version 1.1* Work well and am pleased with it so far ### 5/5 — Star Charts *2011-02-27* This is the real thing! I love the many astronomy apps available, but this one means business. No frills, just excellent star maps. If you us an iPad, you can put away you old paper charts. Thanks for making this available. ### 4/5 — Very Useful *2019-05-03, version 1.3* I bought Star Atlas 2000.0 many years ago by Wil Tirion and find this App to be very similar. Easier than carrying the large paper atlas. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
