Description

Observer Pro is an indispensable app for advanced astronomy observing and astrophotography planning. No more guessing when that galaxy emerges from behind that tree. No more estimating how many hours you'll be able to image an object. Observer Pro gives every astronomer the info they need to make the most of their observing right at their fingertips!

What astronomers are saying:

"Every astronomer with an iPhone should own this app!"
- Astronomy Technology Today magazine

"Observer Pro is the most impressive astronomy app that I have tried out. I enthusiastically commend it to you!"
- Tom Mote, Professor Emeritus, Astronomy

"I have been using it since the day it first became available and I cannot live without it now."
- Sedat B., Cloudy Nights forum

Feature highlights:

• Over 14,000 deep sky objects included, all with closeup reference photos. No need to download anything after install! Sorting and search make it easy to sift through all of them to find which objects belong on your observing list.

• Measure your local horizon profile in minutes with your iPhone.

• Unique charts completely take the guesswork out of predicting object visibility. Your house, trees, mountains, or any other obstructions are completely factored in to all visibility charts.

• New to astronomy? The Featured object list shows a list of objects specific to your location and local horizon that are great for observing right now.

• Keep a list of your favorite observing sites, each with their own local horizon profile. Compare object visibility between sites to find the best spot to setup your scope.

• There's a lot to observe! Observer Pro gives you a place to maintain a list of your favorite objects as well as an observing list that you can take with you to the eyepiece (red-screen night mode is included).

• 7Timer! astronomical weather forecasts for your observing sites are viewable without leaving Observer Pro. They give you the outlook on cloud cover, seeing, transparency, and more. (The weather screen can also be configured to show your favorite weather URL.)

• Simple and intuitive interface makes all these powerful features readily accessible. You don't need to be a Certified Astro Geek to use it (but if you are, you'll appreciate the efficiency)!

• Check out the in-app tutorial (in Settings) to learn more about how to use the many features that come with Observer Pro.

Excellent app to plan DSOs

olympixtk on

I have a limited view from my yard so this is incredibly helpful for planning out which objects are visible and the timing. I’ve tried a bunch of apps and methods and this is by far the best solution. Very, very well done. My only tiny request would be to add a filters. Thank you for an amazing app!

Awesome observing app, easy to set horizons

Bomb #20 on

This is the observing app I’ve been looking for. I am surrounded by woods, with only a few observing windows widely spaced around my property in various directions. I also have an observation site a couple blocks away on the edge of a lake. This app is perfect for comparing the different sites and deciding which is best, and how long I have on target for astrophotography. Also, the method for tracing the horizon at each site couldn’t be simpler. I only had to spend 15 minutes in freezing weather to measure the horizon at six sites around the yard. One little issue I’m seeing is that on my iPad Pro 2022 with iPadOS 17.3 is that when I edit a site name the on-screen keyboard won’t go away when the “Done” button is clicked. I have to close the app and restart it to get rid of the keyboard. One other reviewer also noted this behavior. Also, this app is for iPhone, so those of us with iPads have to deal with the clunky interface. If the keyboard bug gets fixed, and a native iPad version is released, this would be a 5-star app. One last note to those thinking about whether the app is worth $14- considering what you probably spent on your astronomy or astrophotography setup, this cost is a drop in the bucket and it will save you much time and irritation over using other apps that don’t really come close in functionality. However, the developer hasn’t updated this app in 3 years, and it has a bug, so don’t expect curb service for your $14.

Fantastic but not perfect

Utility is wonderfully useful. I do have one bug to report. Once the iOS keyboard is up to search or type it won’t go away. Have to force close and reopen.

Love horizon measurement tool.

It shows exactly when an object comes into view and when it leaves.

Outstanding astronomical observing app

rigpasword on

I concur with what other reviewers have said here. This app is super useful for planning observing sessions. It’s especially useful for those of us who are forced to observe the sky with many obstructions around - tall trees, buildings, etc. The app allows users to build site specific obstruction profiles that then show what objects are visible at what times. Each object in the database has a graph showing if it’s visible and what times it will be visible along with other observing data. Can’t recommend this app more especially if you view from an obstructed site. I only wish the developer would make an iPad version of the app. Clear skies!

Use it every session

Tailspin45 on

Great for planning. Just wish it included planets, comets, and asteroids

How can I get refund

Yasef on

Sorry this app not for me I want to delete it is there any way to get my money back??? Thank you

Really good

Ja57927 on

Excellent app for knowing when your target will be visible and the best viewing times.

Very useful and unique

blank3 on

Very useful in helping prioritize targets for areas with obstructions. Have not figured out how to prioritize targets where I am doing narrow band imaging and don’t care so much if the moon is up. Can sort on just nebula I guess but it still ranks items based amount of time they are up when the moon is not.

Fantastic

BigTenDad on

I’ve used this app for a little over a month now. It has become indispensable when planning for a night of astrophotography. I, for the most part, do not travel with my scope and keep it in one spot all the time. I have a “decent” view of the night sky. Being in an urban setting, I have to deal with buildings and trees. However, with this app, I am able to plan, minute by minute, what I want to image on any given night and even nights in the future. One thing I’d like to see added is a feature that would enable planning to be done across different devices, i.e. iPad to iPhone. Just a suggestion.
