Observer Pro 4+

Outstanding app I love how I can trace my
Tree lines. I use this a lot to plan observing. But I'd love to see frame size (field of view) to see which scope would be best for a selected target. My 80mm apo or My 8" RC. One has focal length of 480 the other around 1500. I wish I could see the target size in my preset views. I also wish the photos were in color. Though that may make the app huge. Still would be worth it to me as I'd delete a lot of other apps for this one if expanded. I also wish there was a faster way to page down through hundreds of dso's in some of the larger catalogs. Flicking a finger up is tiring and slow. Still works so well at helping me see (what's in view) I have to give 5 star rating. I've bought over a thousand apps. Rarely use any one of them. This is the one worth buying an apple device for. I would also like to see the moon in SkyView. I see the curve and the sky is not as dark, but would like to see moon coming and going... is it behind my tree line? This is also where it would be great to zoom in on the circle in the path of sky view and see. Photo of target with scope focal length size?

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.

I've used Observer Pro for several years, and was delighted to find the updated new V 1.2. Now I've been able to upgrade my iPad IOS without losing Observer Pro functionality.

This is the simplest, yet most comprehensive astro planning tool I've found, for anywhere in the world. I use it at home in New Hampshire and on imaging trips in Chile.

It provides basic data including size and current transit time; a photo; visibility charts by hour on any given day, month or year taking moon-phase into account; months of optimal visibility; and sky location for every object in the NGC, IC, Messier and Herschel catalogs.

There's a somewhat hidden object search function at the top of the Catalogs menu.

I particularly like the new Featured option in the catalogs, which selects all visible objects for a given date and location.

The define-your-own-horizon feature is also very handy.
