WHAT’S NEW v4.0:

This was a major release, especially for Apple Watch users, as the extension was rewritten from scratch with a lot more functionality, taking advantage of Watch OS 2.0-4.0 features. A quick preview:

New Watch Features:
– Moon Phase view added to the first screen, moon/sun rise/set times on second screen.
– New (third) screen with the Xasteria weather report.
– Reticle zoom slider.
– Ability to switch mode (Polar Alignment, Bubble Level, Day Alignment, Moon Phase) from the watch.
– Day/night mode switch on the watch.
– Watch type is now automatically detected (manual setting removed)
– Better refresh rate for Bubble level and Day alignment.

Main app changes:
-iPhone X’s Home indicator bar becomes dark when “Night mode” is “on”. (Pro)
-Celestron 7×50 Polaris Finder added.
-“Tool Settings” button in main settings (for global settings previously only reachable through Xasteria). (Pro)
-Moon Phase: Current moon altitude in degrees is shown.
-Calculators: General relativity time dilation and Celsius/Fahrenheit added, default values on all calculators. Long hold on the result of a calculator gives you the option to copy the value.
-Bubble Level: Various improvements including a calibration level display for the compass. (Pro)
-Xasteria weather: Added FAQ, a Fahrenheit/Celsius setting separate from Metric/Imperial (useful in the UK etc) and the background color on the main weather view now shows you whether it is day/twilight/night. (Pro)
-DSO Database: “Sort by distance from me” on search item applies to full list. Return to top button added. Improved the “Point to the sky” function in the Sorting menu with a continuous refresh when you hold the “Select Point” button.
-Lunar calendar: Swipe left/right changes month, Moon phase description added. (Pro)
-Several visual tweaks, most notably a new icon and help fixes/additions.

WHAT’S NEW v3.9:

– US-based server for Xasteria’s main weather service (7Timer), the app will no longer rely on a 3rd party server, which should make it quite reliable. The prediction quality is the same of course – good, but no forecast is close to perfect! (Pro)
– The NOAA water vapor listing in Xasteria got an update, as there was a satellite replacement (GOES-13 retired/replaced with GOES-16). (Pro)
– Clicking on the date or sun/moon rise/set times in the Xasteria results table launches the calendar on the clicked date. (Pro)
– Polar scope reticle centering wizard now has a manual setting tool for mounts whose polar scope does not rotate with the RA axis.
– Fixed behavior of “sort by distance to me” button in DSO DB.
– Bubble level has a more clear indication that you are “level”. (Pro)
– To avoid confusion, the daytime alignment tool selects the target celestial pole by hemisphere instead of where you are pointing to. (Pro)
– Help improvements and quick intro screens when first launching the app and on first visit to the settings.
– Some reticles get a margin when used in the Southern Hemisphere, to allow things like offset display.

WHAT’S NEW v3.8:

– Added rise/set times of objects in DSODB.
– Fixed superimposed Select/Cancel buttons.
– Fixed disappearing copy popup in help.

WHAT’S NEW v3.7:

-Switched to WebKit for faster rendering of help & web pages and copy/paste ability on iOS 11.
-“Force GPS” switch moved to location manager, settings screen label fix for small displays. (Pro)
-Corrected application of stellar aberration – should fix lower culmination discrepancy compared to USNO.
-Added nutation calculation, brings it to about 2-3 seconds accuracy compared to Cartes du Ciel’s apparent coordinate calculations.
-Ecliptic/Equatorial coordinate and Alt-Az to Equatorial calculators. (Pro)
-Julian Date calculator now converts from JD to calendar date and increased to 5 digit (sub-second) precision.
-Atmospheric refraction toggle in advanced settings.
-DSO setting to show apparent coordinates of objects. Bottom buttons reversed to match other tools.

WHAT’S NEW v3.6:

-The “Point To The Sky” sort function in DSO Database now shows icons with the type of objects when showing a list of the nearest objects to where you are pointing.
-When your device does not give the app access to the true north heading, you will be warned and the app will try to calculate true north from the magnetic north.
-DSO DB list view has clearer font.
-Fixed slider/switch issue on iOS 6.

WHAT’S NEW v3.5:

-Point your phone to the sky and sort the DSO database list by distance from where you pointed.
-Fixed Julian Date calculator month input issue.
-A couple of adjustments to the exposure calculator (based on my own eclipse testing).
-When the app upgrades to a new version (not new installations), it will anonymously share the iOS version, reticle and tools used, so that I can focus development appropriately. I intend to keep support for iOS 6/7 devices for as long as I am allowed, even for very few users – but if no users appear to be on an old iOS version, it may be dropped sooner.

WHAT’S NEW v3.4 (2017 Eclipse Edition):

You will note v3.4 has a couple of things very useful for solar eclipses. This was not by chance, as I am going to the eclipse myself. Changes:

-Daytime / no polar scope polar alignment tool implemented (Sun icon). See included help. Works on the watch. (Pro)
-Solar Eclipse presets for the exposure calculator (mostly based on Fred Espenak’s exposure tables).
-Location manager now has a “Map” option so that you can manually set your location by pointing on the map (requires internet connection). (Pro)
-Location manager now shows latitude seconds from your device data (GPS/cellular) in case you need your exact location. You still don’t enter seconds with manual location, as that much latitude precision is not needed for polar alignment. Also, on the upper right of the same screen you see your coordinates in decimal format, in case your mount needs it in that format. (Pro)
-Magnetic displacement shown in Bubble Level & Compass screen. (Pro)
-Water Vapor satellite images source in Xasteria. (Pro)
-Telescope limiting magnitude calculator. (Pro)
-Fixes: Location manager launched from Xasteria was getting its location reset. (Pro)
-Updated to new iOS SDK (better iPad Pro compatibility). Tell me if there are any issues!

WHAT’S NEW v3.3:

– Night mode on/off switch in main settings, applies to the tools that are not related to polar alignment (Calculators, DSO DB etc), as well as help and instructions for better contrast when used in daytime. (Pro)
– New calculators: Solar feature size, Light gathering (Pro) and DSLR exposure calculator. Also, some calculator fields have a button to select from a list of values (e.g. sensor size, reducer focal length).
– Improved look for some tools, increased design consistency.
– Set Zero Position button restored for Skywatcher/Orion 2012-2032 reticle.

WHAT’S NEW v3.2:

-Added Old Celestron CG4/CG5 / Vixen Polaris reticle.
-Calculators improved (e.g. barlows added, icons in list view, localization fixes). (Pro)
-Calculators added (one for free version and more for Pro version including lunar feature size, special relativity time-dilation).
-Alternative forecast options for Xasteria opening in browser window: Meteoblue and Clear Outside (accessible even if Xasteria’s main data source is working fine). (Pro)
-Takahashi 2010-2050 reticle adjusted to not confuse owners of the latest EM-11 version.
-Fixed keyboard not getting dismissed in Set Epoch screen.


-Astro calculators: Over 15 calculators useful for observing and astrophotography, from eyepiece magnification and field of view, to imaging resolution and reducers. (Pro)
-Xasteria uses the 7Timer! service which will be, unfortunately, unavailable for technical reasons for quite a while. Thus, a link to an alternative weather report is provided, and my own server is accessed and a message about the status of the service is retrieved. (Pro)
-Added South Hemisphere versions for two Skywatcher reticles and improved reticle instructions.
-Sharpless 2 catalog added to the DSO DB, as well as 329 named stars and a few more named nebulae, taking the total to over 13000 objects for the Pro version, bright stars added to the non-Pro version.
-Added ability to sort by distance from an alt/az coordinate point in DSO DB.


-Deep Space Object Database with over 12000 objects from several catalogs (Messier, Caldwell, NGC, IC, Herschell 400). The database is searchable and fully configurable with filters, various sorting methods etc. The non-pro version has a smaller database of the Messier and Caldwell objects.

WHAT’S NEW v2.9:

-Vixen GP/GP-DX polar scope added.


-Separated the very old style Synta (Celestron / Skywatcher etc) reticle from the more common “classic” (and actually current for Celestron, but replaced by most others), in order to match better those two reticles respectively. Reticles list re-arranged a bit.
-The “classic” Celestron/Skywatcher etc reticle can be calibrated (using dift alignment or ASPA) so that its epoch matches yours exactly.
-Advanced settings screen improved, “Always show dashed cross” option added (it helps with some reticles to have a horizontal/vertical line for reference).
-Xasteria shows sun/moon rise/set and twilight times. Choice of twilight type in Xasteria settings. Auto/manual location control from Xasteria page. (Pro)
-Fixed polaris centering problem on Watch when paired with 5.5″ iPhone. (Pro Watch)
