I'm thinking about switching from my ancient iPhone4 to something a little bigger and newer like the LG G3. Yes, I know the iPhone6 is coming, but I have available a great deal on the LG G3 for only $99.

I have no interest in software that controls telescopes, but otherwise I have many, many (3-4 dozen?) astronomy apps on my iPhone.

I know that major apps like Sky Safari, are available on Android.

Do software equivalents for
'Scope Nights' (astronomy forecasts for the next week),
'Dark Sky Finder' (matches defined locations to the color coded sky brightness map so you can see which sites are in red, white, orange, yellow, green, etc.),
'AstroPlanner' (shows you how good various sky objects will be over the course of the night), etc.
exist for the Android?

Thanks.

Unfortunatelly, although I prefer Android, iOS has more specific software. I mainly use Skysafari and Star/Solar Walk in my LG G500 and keep my iPhone for the rest.
These programs are sufficient but I miss Observer Pro and Star Atlas.

Whine I am running a Iphone 5 BUT I still use my original old HTC Evo 4G for its astronomy apps...

just because the Evo no longer is connected to the phone network does not mean I can't use it as a wifi enabled computer...

Your iPhone 4 should be able to still use those apps..

My iPhone4 is getting flaky, and I'm not at all convinced that I will still have it available as a 'wifi-enabled computer' in 3-6 months.

Lots of options these days for Android - you may miss some apps from the Apple universe but Android is a fine platform for Astronomy related apps. Clear skies!

I have an LG G2. I have the following apps: Droid Sky View, Stellarium Mobile, Sky Eye, Open Star Map, Planitariax Pro, Polar Finder, various leveling apps.

I also had a I phone 4 and was simply tired of waiting for Apple to come out with a larger phone. I like the G2 for it's larger screen size and processing power, and price. I think some of the IOS apps are better quality, but I do like the G2.

Thanks all.  I will certainly be keeping my existing iPhone, but perhaps giving it a rest and only powering it when I'm planning on going out with a scope.

 

The sale on the G3 passed before I could take advantage of it.  Time to actually look at what else is out there for Android.

Mark, when was the last time you used Astro Panel?  Mine hasn't worked for the past several weeks.  It seems that the data source  - http://www.7timer.com - is no longer available.

Have you used it much?  

 

I downloaded it and it seems that while it has large databases, the features are limited. For example, do you know how I can search for only globular clusters or only for galaxies?  Is there some way to set size and/or magnitude limits on my search? 

 

I am also having trouble with the SkyView.  I see no way to adjust the magnitude limits of the stars or the DSOs displayed. I can't select a DSO on the screen by touching it, only the stars can be selected.

 

I am using a Nexus 7.

Thanks Mark.  Your URL works on my desktop, but www.7timer.com comes up as 'Web page unavailable' both on Chrome and IE.  As I mentioned, Astro Panel no longer functions on my tablet either since it's unable to download any data. 

 

Ah!  The wonders of modern technology!

You could search for only globulars, or only for galaxies or both and set size and magnitude limits.

Go to DSO Selection, press Select. Then there are two ways.
1. Go to "Basic search/Object types" and select the object types you wish to search for. Go to "Select object only from catalogs" and deselect Messier (it is set on by default). Go to "Visibility filter parameters". In filter type select "Maximum magnitude filter". In "Set maximum magnitude" select the limiting magnitude. In "Object minimal size" select the minimal size for the object

 

2. Go to Advanced Search . Press Add new search request. In Set SQL request put  

type=gc for globulars
type=gx for galaxy
type=gc|type=gx for both globulars and galaxies
(type=gc|type=gx)&(mag<12)&(a>5) for both globulars and galaxies below 12 mag and with size above 5 angular minutes

You could leave "Set local request" blank or if you wish to search only for objects above say 20 degrees during observation period put alt>20 there.

Press OK and select this search request in the list.

 

Go back to "DSO Selection" and press update button. There is a list of objects fulfilling your criteria in the current database (NgcIc by default). Add all or some objects to the observation list (long press, "Add to observation list"). Or if you press on the object you could see where it is located in the sky view.

Go to menu to switch the database (e.g. UGC) and new list of objects will appear again, this time for new database. Add it again to observation list.

 

 

 

ONLY objects in current observation list (there are four obs lists, you could choose current obs list in Observations Lists menu) are displayed on sky view and could be selected there. By switching observation lists you could easily change the objects you see on sky view. Objects are displayed as icons at high FOV and as ellipses at low FOV.

 

When you say you could not select an object you probably mean that you could not select the DSS image supplied with the program (messier and caldwell). This is because it is just an image of the sky part, not the object in observation list. You could download image of any sky part yourself. Just press Menu/DSS in the Sky View. You could easily find an object on DSS image. Press any star close to the image and go to Menu/Nearby. Set detection limit to 0 and select NgcIc database only (for quicker search). There should appear an ellipse representing an object.

 

Star magnitude limits could not be adjusted at the moment, they are selected automatically and the lower the FOV the more stars you see. Still you could select the stardatabases to use (Menu/Settings, Star Catalog Layer).

 

Re magnitude limits. There is an application discussion forum (http://groups.google...soplanner?hl=en) where you could leave your suggestion

 

There is a detailed manual in PDF format on the program site (http://www.dsoplanner.com/help.pdf)

Thanks for the pointers.  A couple of comments:

 

- It did not seem to be an image but just a square box.  

 

- The fact that only objects in a current observing list are visible in Sky View is a real issue for me since I like to browse the sky to select objects.  I wondered why I wasn't seeing any DSOs.

A square box (DSS contour) represents DSS image. It shows at high FOV to see where images are. At low FOV they turn into DSS images. To observe the way you do I could suggest you make a large observation list (1000 entries per list is allowed) and then all 1000 objects will be shown on the sky. E.g. in DSO Selection/Advanced Search select id>0 request and add the resulting objects to obs list, or make an id>1000 request this will give you another 1000 objects etc. Or you could make large observation lists according to other criteria in several iterations (e.g. first search for bright objects, then for small, pressing Add All to observation list each time). Another approach could be to search for nearby objects around bright objects etc.

Another approach would be to select the whole database (id>0). And then in DSO Selection filter it by constellation. The resulting objects could be added to obs list. When you switch to another constellation, clear the obs list and filter objects by new constellation again and add them to observation list.

 

By the way galaxies from Principal Galaxy Catalog are shown the way you are accustomed to.

To address the stars lowest magnitude limit you have 2 options available already in the Star Chart menu.
1. Select Settings and turn off the UCAC4 star catalog, leave the Tycho catalog only (down to 12m). Still too many stars? Disable Tycho as well.

2. You can visually fine tune the "Boldness" gradient of the stars displayed. Select the "Boldness" menu item and move 2 handles independently to make bright stars larger, and the stars you don't care about much the size of a single pixel - almost invisible on a high res display. This settings are saved independently for each zoom level of the star chart, so you can fine tune the look at any zoom to your liking.
Try out these options, it might be sufficient for your purpose.

Also regarding the "no DSO objects" question: simply put, the Star Chart is a secondary feature of the application. The first one is the Planning. Decide what you want to see first (populate the Observation List worksheet) and then generate a nice uncluttered Star Chart for the job out of it. Also you have an ability to prepare up to 4 independent observation lists beforehand to display on the Chart separately, quickly switching between them in the Observations List menu.

By the way, I've just got the vendor status on the Forum. To limit the clutter in this topic, I would suggest going there for further discussion, if nobody mind: http://www.cloudynig...-astronomy-app/
