I was introduced to sky portal when I got a celestron go to telescope a short time ago and it’s become my primary astronomy app since it easy to use, contains a through library of visible objects in the night sky of the northern hemisphere and with the compass mode gives you a rough view of the sky you are looking at in real time, my only recommendations for anyone using this app would be to use it on a iPad or tablet over a smartphone as the arrow keys used to slew a telescope and the crosshairs used to target an object can be tricky to use on the smaller screen. It would be nice if there were more satellites and objects listed maybe that’s what Sky Safari Pro is for and I may upgrade one day but at the moment Sky Portal meets the means for my backyard astronomical observations. App is 4 stars

Great App

I use this app with my Celestron 11” Edge HD and the CGX mount. I also utilize the Star Sense camera with it for alignment and it works beautifully. The only issues I have are the Celestron focus control is very sensitive and very confusing and almost impossible to use and updates to the app to include data for new comets are very slow to occur for example the latest new comet Neowise has been visible for a while now and it is not listed in SKy Portal but has been in the Sky Safari app for quite some time now.

Great app for learning and controlling telescope. One improvement.

I love this app however I have one suggestion for improvement: When using the audio guides in the Info section, let the audio playback continue to work when the screen locks or auto locks. Many people have their phones set to auto lock after as little as 30 seconds and when this happens any audio playback currently in progress instantly shuts off when the phone locks. Only unlocking the phone will instantly resume playback. Seems like that improvement should be possible based on many other apps out there being able to play audio while the phone is locked. Thank you!

Works, but not as I want it to

I finally got my first celestron 6se telescope that is one of the Best purchases I’ve bought. With that, I also bought the WiFi module that connects to SkyPortal. For about five months I was trying to align the app to my telescope. The app estimates where your telescope is pointing for extra accuracy, but for an odd reason, my pointer on the app is nowhere close to where the telescope is actually pointing. Though this is a minor problem one may say, but because the pointer on the app is so inaccurate, whenever I try aligning, the second star always says that there was an error. The error was that the app says that the alignment for, say Jupiter, is impossible in that location. If anyone can help, it would be greatly appreciated.

Junk

This is a terrible downsized version of a great app (sky safari). It will not consistently go-to, it won't keep the settings that you've put in the hand controller (max elevation,cordwrap!etc.) the cordwrap setting doesn’t work—if you try to use this with your scope remote it will wrap itself to a grinding standstill. The only reason I have this is that it is the only thing offered with Celestron's Wi-fi module. I'm junking both the module and the program and going back to the Orion setup that allows use of SkySafari Newest view—-IF you have sky safari already you can use the Celstron wi-fi module by bypassing this junk and selecting “Celestron Wi-Fi “in the telescope drop down in the Telescope settings in SkySafari .It ties you in and works!! (Even though your scope is NOT a Wi-Fi scope)

Has a major issue!

Discovered that the app has a bug where it does not show any Deep Sky Objects (nebulae, galaxies) on the sky chart. I tried every single option in settings to make them visible but nothing works. You can search for them and then it will center them BUT no luck in getting DSOs to show up in charts. I found a review from 2 years ago complaining about the same thing so not a recent issue so guessing Celestron is not planning on fixing it. I bought the wifi adapter for my 6SE to use this app to find and slew my scope to objects in the sky but without seeing DSOs on sky chart that severely limits it. Too bad. Will be returning the wifi adapter.

Issues on new update

Hi, new update for iOS14 has a problem! the app doesn’t run! (My device is iphone SE 2016)

4 years ago, Z-Leroy

Why all the poor reviews?

This is a very nice app. Especially considering that it is free, has no annoying advertising, and has many features that are similar to starwalk2. It searches, uses current location, shows planets, stars, constellations, and much more. If one clicks on an object, it offers an audio description of the item. Give it a try, you will not be disappointed.

Needs red mode

I’m surprised that a telescope control app does not include a mode to change its color scheme to shades of red. This app has either full color or grayscale. The “Star Chart” app has a red mode to help preserve your night vision while showing a chart of the night sky wherever you point it, but isn’t designed to communicate with and control a telescope like SkyPortal. Please add red mode to let us control our telescopes without destroying our night vision. That will raise this review to five stars.

Great App, but focus motor control has issues

I have a NexStar 8SE with a focus motor as well as the SkyPortal wifi module. Connecting to the module was very easy and its fun using my phone to navigate around. My main issue however is with the Focuser controls. Any movement in the positive direction using the fine focus buttons works fine, but any movement in the negative direction causes several focuser rotations one way, then back to the position I decreased it too. Seems like it should only increment a little bit, but it doesn’t.

This app is underrated

This app is amazing the people that develop this did an amazing job like jaw-dropping. It’s incredible to locate every star ,every planet ,every dwarf ,planet every ,galaxy every constellation, every moon. It even gives you facts about all of those it. It’s astonishing it’s hard to explain how much I love this app I really really recommend you downloading this!!

Not very usable with iPhone XR

Downloaded this app too check it out. Sounded great on the Celestron web site. I installed it and just tried compass mode. When the phone is held still, the images bounce around like the phone is vibrating. It's unusable in compass mode without some kind of dampening. I liked star maps and features but because of the jumpy screen issue I'm deleting the app. Maybe I'll try it again in six months of they address the issues I mentioned.

A software failure due to limited scope. Has drop out connection to my Celestron 1100 CPC.

I ordered the module and assumed it was a problem with it. Sent it back for repair. In the meantime I purchased the Sky Safari module package and also the Sky Safari Pro app from apple App Store. Man did it ever work great!! Just received the repaired Sky Portal module. Still did not work. After reading other similar problems with the Sky Portal app., I must conclude that the app is overpriced at ‘free’. It appears that Celestron’s Sky Portal app is lacking the required software to fit the job required. Do not waste your valuable time on this app folks!!!

Doesn’t Connect

I used to us this with my Celestron scope but when I got it out for the recent lunar eclipse it wouldn’t connect. Tried with my iPad and my iPhone and neither would work. A day or so later decided to buy SkySafari and try it and it connected and worked. I feel that they need to do a update, maybe not compatible with the latest IOS.

Excellent search options, best items for viewing in your area, and a great map. Would love it if there was a check box to check if you found the item so you could log when, where, and what you saw.

Very easy to use and great features

I use the app with an AVX mount and various refractors. Setup, alignment and calibration are very easy. Acquisition and tracking work very well at all magnifications. I use the scopes for visual astronomy, and it is the best I have had it in 30 years of observing. Thanks so much!

It’s ok but even though it has access to my location it still doesn’t always provide accurate results. It’s like it still doesn’t know where it’s at.

Wow, this is bad!

Something seems terribly wrong with this app. No deep space objects visible at all, despite the menu setting saying otherwise. The deep space objects are there, but you have to enter their names individually in the search menu. Seems to be missing half of the basic features in the free version of Sky Safari. I got this hoping to use it to control by CGX mount. But it’s unlikely this app will be any use for that.

Adequate but limited

I have used this app with a NexStar 5SE and the Celestron WiFi adapter. I had no problems controlling the scope. The object display left a bit to be desired. Messier objects are not displayed until chosen and then only individually, disappearing when the next object is chosen. Star density is not easily set, if at all. Custom lists do not exist. Get SkySafari 5, it’s free and has more bells and whistles.

3.3.4 update is crap

This app used to work fine until my iPad updated to 3.3.4. Now it won't open. I can't even use my Celestron telescope to view the fall skies with the features and convenience that Celestron designed. What a waste of some terrific fall evening weather. I really hope someone is reading these reviews and will fix this soon.

Doesn’t play well with Starsense.

Initially seems to work well, but when my Celestron 9.5 Edge is repositioned e.g. for a new viewing session, the app remembers the old alignment and will not perform a new align. No way to reset the alignment parameters as far as I can tell.

Used to be a good app.

I don’t know what they did to it with the last update but now in compass mode the horizon curls up as I point my phone to Zenith and for some unknown reason it’s showing a comet images where there are no known comets. Bad job guys, you ruined a good app!

Most recent release introduced a new feature, infinite CTD’s.

I have been using this app with my iPad Pro 12.9,” and I cannot say enough how wonderful this app is. It felt so refreshing to be using an app that wasn’t developed specifically to nickel & dime the user every second. Plus, the fact that this app is able to scale to the 12.9” Pro’s screen size correctly makes it even more enjoyable. I love the overall UI design as it is very intuitive for the most part. Yes there are plenty of both single payment and micro transaction based apps that may offer a bit more. Though when you consider that at least for now, this app is completely free, the app itself becomes quite a compelling offer. That being said, only time will tell if this remains the case in future versions of the app. Unfortunately, two things are impacting my current rating. First is the red night vision option for the UI of the app. While I do not find this UI setting bad, I would prefer if it also had a custom color option as well. If I am using the app for a long period of time at night, the red causes my eyes to feel strained. Also, the red in fact can also make it harder to see the overall UI. Perhaps a night vision like setting using a single or custom color option that allowed you to see the app information would be better than just a simple all red overlay. Second is a more pressing issue that I already see other reviews bringing up, the new unending startup crashes. Since the last update, I cannot use the app at all. I’m running iOS 11 currently, and all I see is about 10-15 seconds of launch screen before immediate crash to home screen. This needs to be fixed in the next update as the app is currently useless right now.
