Each entry contains essential information for the object, such as size, brightness, and distance, as well as stunning images from the Hubble Space Telescope and other observatories and satellites. No internet connection is required for the basic data and images, but a link is provided to open a Wikipedia page on the object for more information if you do have internet.

Convenient for experienced astronomers.

Impress your friends by instantly accessing facts on the objects they are seeing in your telescope.
Make it your personal list by checking off objects you've seen, or intend to.

Features:

- "About" screen with explanations of the catalog and data.
- Support for Apple Watch! Holds information for all of the Messier objects on your wrist, including images. Supports Apple Watch complications for quick access.

The object list on the iPhone and Apple Watch shows at a glance the Messier number, object type, and the constellation it appears in, and on the iPhone, a thumbnail image and common name, if any.

### 4/5 — Very handy

*2022-09-04*

Nice images and all the basic info needed to find the objects. Needs a search by name function.

### 3/5 — A good app

*2020-02-22*

This a good looking app and lists everything you need to know, but this could be a great app if it showed what targets were visible at the time of day you are looking.
I’m not talking about adding a sky map, but it could highlight the targets that are above the horizon and visible,  so I have given it a 3 star rating, but if they could add this feature it would be a definite 10 star app.

### 5/5 — Similar to the 32 bit version that Apple killed

*2019-01-26*

Useful little app, especially if you want to keep track of the Messier objects you’ve seen.

### 5/5 — Messier Marathon

*2018-07-23*

Great app for logging and working on the Messier Marathon list which occurs - once a year in April - when it’s possible to see all the objects in one night.

### 5/5 — Easy and exactly what I was looking for

*2018-07-09*

I just wanted a simple listing of the Messier objects that I could check off once I had found them...along with easy access to see a listing of the objects accompanied by a visual. Perfect!

### 5/5 — Great resource

*2017-02-18*

A great little app for referencing the Charles Messier list. Nice to check off the objects you have seen and the link to Wikipedia is easy to access.
